Projects
This page is where I post some of the machines I have worked on, along with what it took to get them running again. This is not a list of every single machine I have repaired, but does capture most of the bigger projects, along with some that I have found the most fun. If you are working on a machine with a similar problem to one described here, feel free to reach out and ask me questions. If you would like to see me write about more of my projects, also feel free to let me know that!
Apple III - March 1, 2026
This Apple III was recieved by me as a trade for my labor on a customer's Apple Lisa 2/10. This particular unit is far from perfect (with quite a bit of corrosion from a previous battery leak), but it is complete, and even has a Disk III external disk drive! When I got it, I started by tearing it apart and doing a full inspection/cleaning, and I was not surprised to find that someone had previously enjoyed a smoke show and blew up the safety capacitors in the power supply. I removed and replaced the two safety capacitors, as well as cleaned up some of the corrosion on the bottom pans, cleaned the disk drive heads, and attempted to power the machine up. To my surprise, the system turned right on, passed its memory diagnostic, and attempted to boot the operating system from the bad diskette I had inserted. I was quite impressed, as I have only heard terrible things about the Apple III's reliability, and this one was running with a very corroded section of the logic board and a previously untested power supply. Now that it is turning on and attempting to work, I need to do some future proofing to make sure the corrosion doesn't get worse, and the system will be reliable for years to come. I also need to write some new operating system diskettes so I can properly boot the system. I did replace the belt in the Disk III with one from a spare Disk II because the Disk III's belt was broken. I also have what seems to be a hard drive interface card, so I will be testing that out and will see if I can source a compatible hard drive so the machine can have mass storage. I will be keeping this updated as I go! Updated 03/04/2026
Apple Lisa 2/10 - February 15, 2026
The Apple Lisa was the machine before the Macintosh, and was overall seen more as a failure in Apple's history, but it did play an important role in getting the average person to use a computer with a graphical user interface. That is why, when I was contacted by someone on Facebook asking if I would be willing to repair his Apple Lisa, I said yes. I do not normally take in machines for repair, but I made an exception for this one, because of the historical importance and the chance to use one (let alone fix one!) doesn't come along very often. This system came to me because it was seemingly completely dead- it would not turn on. It did try to start though, and the +5V standby power was getting to the logic for power control (the Lisa has "soft power"), but it would only make a little sound when the button was pressed and the power supply wouldn't start. After bringing the PSU to the bench, I quickly found that there was a shorted Motorola MR854 rectifier diode. I took a quick trip to Ax Man in St. Paul, and by some miracle, they had exact replacements in stock. Within 36 hours of having the machine here, it was turning on, passing its diagnostics, and it even booted the operating system from the original Apple Widget hard drive! I also went ahead and replaced the capacitors on the video board, and also replaced a voltage regulator as I have had bad experience with them failing short in the past. Another tech had replaced the capacitors in the PSU four years ago, so that was thankfully not a concern. The keyboard didn't work at first, but it is a foam and foil keyboard, so it is typical for the foam to deteriorate and for none of it to work as a result. After waiting about a week for parts, I rebuilt the keyboard and the whole system was finally fully functional. It has since returned to its owner, and he traded me an Apple III, which will be the next Apple failed product project! Updated 03/04/2026
Apple Macintosh Portable M5126 (Backlit) - January 17, 2026
The Macintosh Portable was Apple's first attempt at a laptop, and it sure shows. I would say it was a solid attempt at it though- it featured a full 3.5" hard drive, a massive lead acid battery pack, a backlit display, 2Mb (yikes!) of RAM, an Alps mechanical keyboard, modular trackball/keyboard placement, a 3.5" floppy drive, and others. It is quite a chonky beast, but being from the late '80s, I think they did quite well, especially after looking at the competition. This system did not work when I bought it. The logic board capacitors were all leaking, a few traces were broken, and the main battery (necessary for powering up the laptop) was dead. I replaced all of the leaking electrolytic capacitors on the logic board with tantalum equivalents, replaced the capacitors in the power supply, purchased a new battery, installed a hard drive emulator (to conserve power and make it quieter), installed a mute switch inline with the speaker so I could disable sound, and did as any college student would do in 2026 with a laptop from 1989- brought it to class! I took notes on it in one of my computer architecture lectures, and it held up great. It ran off the battery pack for the whole 2 hours, the keyboard was great to type on, and the system remarkably didn't crash. I may bring it to class some more, but for now it waits around here for additional use, and gets brought out to write floppies for other systems on a fairly regular basis. It is also fun to use it to telnet to my servers, as the hard drive emulator (BlueSCSI) also provides SCSI to ethernet emulation with WiFi support. It is a great machine, and I'm happy to finally own one. Updated 03/04/2026
IMSAI 8080 - January 17, 2026
This is one of the most well known home computers of the '70s. This IMSAI 8080 system came with dual 8" Pertec floppy drives (in an ICOM disk unit), tons of spare S-100 boards, a Video Terminal Interface (keyboard and television with a corresponding S-100 board), and many 8" floppy disks to archive. Among the floppy disks was a diskette for an operating system that few versions still survive of, ICOM FDOS. This particular diskette is more complete than most already archived and was configured specifically for these drives and video terminal, so it was important to make copies of it before booting the system. Thankfully making additional copies wasn't very difficult with the other 8" diskette hardware here, and I was able to repair the IMSAI and get it to boot FDOS within a couple weeks of acquiring the machine. The system is overall in amazing condition, and was well maintained by its original owner, whom I purchased the machine from. Next for this system is making an easy way to archive the remaining 50+ diskettes, and experiment with running other operating systems (such as CP/M), as many people would have done on S-100 era hardware. Updated 03/04/2026
DEC VT320 Terminal - October 26, 2025
This is a terminal, built by Digital Equipment Corporation in the late '80s through the early '90s. This particular unit was made on December 22, 1990. It has a green phosphor CRT, other variants were made with white or amber phosphor CRTs. I purchased this locally, and bought a keyboard on Ebay to complete it (the keyboard is DEC proprietary). I also had to install a DE-9 cable for serial, as I do not own any of the proprietary DEC cables to connect to it (pinout in the photos below!). It is a reversible modification, but necessary for me to use it. I have connected a few of my machines to it so far, such as my Slicer single board computer, SGI O2, and Space Byte 8085 computer. It is quite nice to have a real terminal finally, especially one that natively uses the same terminal interface we so commonly emulate on modern computers (VT100!). At this point it works quite well, so I don't think I will do anything to it yet, but it would be a good idea to change the capacitors in the near future as preventative maintenance.

IBM PS/2 Model 95 - October 9, 2025
I purchased this tower from Free Geek Twin Cities in "we gave up!" condition. It didn't output any video, and by the time I got it home, it wouldn't even come up over the serial port. I went through the whole system, removing and reseating everything, while cleaning contacts with Deoxit. To my surprise, the system fired right up with video output and all! The floppy disk drive, while technically working, is plagued by leaky capacitors so it will need to be stripped of those, cleaned, and repaired. For now, the system borrows a 2.88Mb drive from one of my Model 57 units, and I installed IBM OS/2 Blue Spine (for Windows compatibility) on the machine. It now makes for a great Tetris rig, with a BlueSCSI running as the SCSI hard drive for reliability. Updated 11/06/2025
Linolex 3032 - September 28, 2025
This is a system that there does not seem to be much information on the internet for. It is a general purpose computer from the mid '70s, built by Linolex, which was later acquired by 3M. I am missing the CRT/Keyboard unit that would have connected to the main machine. If you have any further information about this machine, or know of any surviving software or documentation, please let me know! We currently do not have any software or documentation archived for it, so it will be a big reverse engineering project. It has two Shugart 900 8" floppy disk drives, which are a proprietary interface. We plan to start making schematics of the logic boards in the near future. Updated 11/06/2025
Slicer Single Board Computer - September 27, 2025
I purchased these from a guy on Facebook, as is the way I get many of my machines. I didn't even know I was getting the first one until I took apart what just appeared to be a homemade 8" floppy drive enclosure to find a single board computer bolted to the top of one of the drives! It turns out that was a complete standalone computer system, so I intend to restore it to be that way. I took a vacuum to it when I first got it because it had been used as a mouse house, with turds and corrosion as well as a nest built inside on top of the power supply. After cleaning it all up, I tested the PSU, which turned out to miraculously be working. I reassembled the odd machine and tested the computer and drives, to find that both drives show signs of life (although not working properly). The computer itself works perfectly over serial. This is again another oddball machine that doesn't have any software with it, but I did find the original manual for it. I later returned to the same place and purchased a second unit we had found, so I now have two of these kit single board computers to work with. I will need to write my own software or port CP/M over to it, which will be an upcoming project. Updated 11/06/2025
IBM RS/6000 44P Model 170 - September 15, 2025
This machine was brought to me by Eric (creator of BlueSCSI) from VCF Midwest. It is a server/workstation that would run AIX, IBM's version of UNIX (the same operating system the server that is serving you this page is running!). The system is working well, but didn't have a hard drive and the CD drive is not working. I installed a SCSI hard drive, and installed AIX with a BlueSCSI emulating a CD-ROM. It works great, running AIX 5. I am planning on possibly making it a file server, or it may become the workstation that sits next to me at my desk. Updated 11/06/2025
Space Byte 8085 S100 Bus Computer - September 5, 2025
This is a system I purchased on Craigslist, from the original owner. He doesn't remember much of what he used it for, but he did have the original manual, which has now been archived! He kept the system in wonderful condition. The first thing I did when I got it home was bring it up on a Variac (variable AC transformer) slowly to make sure the power supply capacitors had a chance to reform. The system came right up perfectly, with the PSU voltages being extremely stable. The processor and 4/5 of the RAM boards seem to be working great, but we do not have any software at this point for it, so anything I do will have to be written or ported myself. The goal is to eventually get it running CP/M, so it has an OS to run software from, and I plan to pair it with one or two 8" floppy disk drives. This one is a developing project! Updated 11/06/2025
Sun Ultra 60 - August 31, 2025
This machine came in the same lot as the afforementioned SGI O2, and this machine was a much easier system to get up and running. It came with a couple of hard drives in their proper sleds, but had a dead clock chip battery. I performed Dremel surgery to modify the chip for use with an external CR2032 cell, and then reprogrammed the MAC address. With these things taken care of, the machine was ready for its fresh install of Solaris 8, and is working great. It has been up longer than the O2, and has also proven itself to be a reliable workhorse, and a good space heater. Updated 11/06/2025
Silicon Graphics (SGI) O2 - August 31, 2025
I acquired this machine in a small lot of UNIX systems, in "project" conditon. It did not start up, and would just flash a red light on the front when plugged in. This ended up being a simple problem caused by dirty connections. I went in and reseated all of the RAM and the boards into the backplane, and it started right up! That was the least of the struggles though. It did not have a good hard drive, so I had to replace the hard drive, and then learn how to install IRIX. Anyone who has installed IRIX before knows how much of a pain it is, and it is made even worse when the optical drive doesn't work at all, so I was stuck learning how to do a network install. Thankfully, there is a handy tool out there, called "LOVE" (yes, we love that tool). I installed it on my Ubuntu laptop, connected the Ubuntu laptop directly to the O2 with an ethernet cable, configured IP addresses, and ran the program- the O2 liked it and did a net install (with a ton of commands entered on my part). Once completed, IRIX itself is actually incredibly intuitive, so it has been fun to mess with. It has had a cumulative 40+ days of uptime running here, and seems to be running great! It has been fun playing with the video recording tools, and I intend to either install or create an application that allows streaming over the network- more on that in the near future. Updated 11/06/2025
Power Macintosh 9500/150 - August 8, 2025
This Mac was purchased from Garrett over at BitHistory.org. It is a bit of an odd one, considering that it was downgraded to a 100MHz 601 PowerPC processor at some point in its lifetime. After reseating the processor card, the machine sprung to life and booted an install of MacOS 8 from its IBM 2Gb SCSI hard disk. It appeared to have been used in a realtor's office, with photos of houses, Photoshop and other editing software, and all software was licensed to "Iowa Realty". The disk has since been wiped and moved to my Macintosh Classic II. The PM9500 will receive a BlueSCSI with a fresh install of MacOS 8.5, and will run as a file server for my various vintage Macintosh systems. I plan to recap the logic board and PSU in the near future. Updated 8/14/2025
Macintosh 512k Hyperdrive - August 6, 2025
This Macintosh was purchased from Free Geek Twin Cities as being mostly functional. The computer does boot off of the hyperdrive, but the install is corrupted, and the display wobbles. It will be fully recapped eventually, but for now it waits its turn in the line of repairs. Updated 8/14/2025
Original Apple II - July 28, 2025
This is the oldest Apple machine in my collection. It is an original Apple II, serial number 22218. It is a relatively early example of an Apple II, and it came from the University of Minnesota Twin Cities. It currently does not work, but it is on the list for repairs. I recently acquired an EPROM reader, so I can archive and compare the ROMs to verify they are ok. This machine does have one odd ROM in it, labeled ABW. I am not 100% on the origin or use for this ROM, and also haven't gotten great reads of it either on my EPROM reader, so we may never know unfortunately. The keyboard in this machine also has about a 50/50 ratio of working keyswitches to non working switches, so I will likely need to go the modern replacement route to get it working again. This one is an ongoing project. Updated 11/06/2025
Macintosh Color Classic - July 25, 2025
This machine was in rough shape. The logic board was covered in grass, dust, capacitor goop, and the battery had started to leak. Thankfully the battery leakage was contained to just the battery holder, and the capacitor corrosion cleaned up nicely. The logic and analog boards are completely recapped, and the machine is back in service. The RAM will be upgraded at some point and the display could use some geometry adjustments, but for now I am just happy it is running and booting off its original IBM hard drive. Latest Update: The floppy drive has now been cleaned and lubricated, and the hard drive swapped for a BlueSCSI to give the machine network capabilities and a solid state hard drive option. Updated 8/24/2025
Macintosh 512k Take 1 - July 15, 2025
I picked this Mac up locally on Facebook marketplace. It has an internal SCSI upgrade, but aside from that, is a standard Mac 512k in fairly good condition. The keyboard has a broken jack, but that will be replaced in the near future. It even included the original carry case, which is probably the main reason I bought this one, but of course the SCSI upgrade is nice to have too. It is in line for a full restoration/recapping. Updated 11/06/2025
Macintosh SE/30 - June 22, 2025
When I acquired this machine, I started by removing all capacitors from the logic board and cleaning up the corrosion. Thankfully the battery had not yet leaked in this unit. After that, I installed new capacitors and the machine runs and boots, but had video issues. After purchasing new ICs for the video circuit and replacing UE8, the system would start up with proper video. I did notice the sound was unreliable though, and that ended up being because the molex power connector had the -12V line corroded through on the logic board! After replacing that connector (with one from an ATX style scrap PC board), audio was significantly better. Now that this machine is fully serviced and running, I will be installing A/UX on the internal BlueSCSI hard drive emulator, to experience Apple's odd version of UNIX from the 90s. Updated 11/06/2025
Silicon Graphics (SGI) Indy - June 13, 2025
To say the SGI Indy has been a terrible experience for me so far is an understatement... I got my first one for free (thankfully!) to save it from being thrown out, and it has got one of the notoriously bad Nidec power supplies. In the meantime, I have purchased two more Indys (why do I buy more of these??) with the intent of fixing all three, and selling the extras. Between the three, I still don't have a working system. I've got two bad power supplies, at least one dead system board, and possibly other issues I haven't figured out yet. The one machine with a good PSU starts up and pretends it wants to work, until you try to install IRIX and the system locks up (exactly what you want). The Indys are an ongoing project, but a fairly high priority one as I would like to decrease the number of duplicate machines around here. I will update this post as progress is made, for now, they can rest in pieces in my closet. Updated 11/06/2025
IBM Portable Personal Computer 5155 - June 8, 2025
The term "portable" is definitely relative here, this thing is a beast of a hacked together machine, but it is incredibly well built. IBM essentially took a 5160 motherboard, CRT, two half height floppy drives, Model F keyboard, and a modified PSU and crammed them in a giant metal frame, covered by the same quality plastic found on other IBM machines of the era. This particular unit needed the typical tantalum capacitor replacements, but it works great after that work was done and the floppy drives were cleaned. I installed a XTIDE/CF hard drive emulation ISA card, as well as a serial card so I have flash storage and serial connectivity on the machine. It is a fun dinosaur, and definitely an important part of the portable PC's history. This one will definitely be in the collection for the long run. Updated 11/06/2025
IBM RS/6000 43P Model 140 - May 22, 2025
This was an Ebay purchase, as I had been looking for this model of RS/6000 for quite some time. It arrived to me in pretty good shape, but had quite a bit of rust along the top edge of the case and frame that needed to be dealt with. The whole machine was dismantled and cleaned while the frame and inside of the case was sandblasted and painted with a conductive compound. It is fully operational, and has been upgraded to have two 9Gb 68 Pin SCSI drives, 768Mb of RAM (Max supported), a 100Mb ethernet card, and was given an install of AIX 4.3.3. It now serves this site, running 24/7. Updated 8/15/2025
IBM PS/2 Model 57SX and 57SLC - May 16, 2025
I acquired 9 non-working PS/2 Systems as a set, all of which had dead power supplies. I tested all 9 system boards with a good PSU to confirm all of the rest of each system still worked, but the power supplies were definitely bad. After much troubleshooting, I found the diode packages on the output side of each power supply are prone to failing short, and sometimes that will blow up the transistors as well (I even had one fail this way on the bench while it was running!). I have drawn up the board layouts for all of the components on the 3 PCBs in this model of power supply. I have since sold off 7 of the machines (keeping one of each for my collection), but am working through PSU repairs on all of them. I have repaired two so far, by replacing all electrolytic capacitors (some were leaking), the two transistors, two resistors, and the commonly failed diode packages. Units that have been repaired have been working reliably since! Feel free to reach out if you are also working on such a power supply- I have spent way too many hours with these and may be able to help. Updated 8/15/2025
HP 9000 K220 - May 16, 2025
This server is an absolute beast. When it was new, the cost in its current configuration (four processors, 2Gb of RAM) would have likely been over $100,000. This machine was acquired from Garrett over at BitHistory.org. It has been cleaned inside and out, has had its four hard drives wiped, and HP-UX 11.00 was installed. It now has an IBM 5150 that sits on top of it as the terminal. The machine pulls upwards of 400 Watts while running, making it the most power hungry machine in the collection (and is definitely the loudest!). Updated 8/15/2025
IBM AS/400 Model 170 - April 27, 2025
This machine begins my experience with the odd systems that are IBM Midrange. This is a system that once would have been running financial programs, but is now oddly in my living room. It runs IBM OS/400, now referred to as IBM i. My particular machine runs V4R4. It unfortunately did not have a license key on the clean install, so I am stuck reinstalling the OS every 70 days (thanks a lot, IBM). The system was in operational condition when I purchased it- it came with the base unit, some documentation, cables, a Twinax terminal, and its corresponding battleship IBM Model M keyboard. The keyboard will need to be bolt modded at some point, but it is awesome to type on. There is a small but great hobbyist AS/400 crowd, and they are the ones who helped me through installing OS/400 on this system. I hope to make it do more at this point, but for now it is waiting on its next OS install. Updated 11/06/2025
IBM Personal Computer 5150 - April 5, 2025
I purchased this machine as a set from the original owner. It was sold to me in non working condition, but the issue ended up being a shorted tantalum capacitor on the logic board that was preventing the machine from starting up. After replacing that capacitor, the machine came to life and worked perfectly. I went in and replaced the rest of the original tantalum capacitors as preventative maintenance (they tend to explode when they fail, so best to replace the 40 year old parts). The machine now has an XTIDE bios card that also has hard drive emulation on a CF card, so the system can remain looking original from the front, but have fast and reliable flash storage hidden in the back. I also installed a serial card, so the system can run as a serial terminal for my HP 9000 series server. It is quite a fun machine with the color monitor! Updated 11/06/2025
IBM RS/6000 Model 7011 and Xstation 130 - March 23, 2025
I got these machines as a set- two Model 7011 RS/6000 servers and one Xstation 130. One of the RS/6000 machines is a parts machine, missing the front plastics, floppy drive, hard drive, RAM, and other parts. The other is a complete machine with a frame buffer card, and is operational (although it very much needs a PSU recapping). The Xstation was difficult to find a monitor for, but once I found a monitor for it, I found that the PSU had failed, so I recapped that. The Xstation 130 now works very reliably, and is set to boot from my RS/6000 43P. Updated 8/15/2025
Macintosh 128k Take 2 - February 28, 2025
This is my second Macintosh 128k, but I purchased this one because it is more original than my first one. This machine has a 400k internal floppy drive (low density, single sided), wheras my other one had an 800k drive (upgraded). The floppy drive had some problems, mainly a failed hall effect sensor located in the most inconvenient part of the drive, right under the motor. I had to purchase the obscure sensors from a random place on Ebay, tear down the drive to the bare minimum, and dismantle part of the motor housing to get to the sensors. I was able to sucessfully desolder the old sensors and replace them with the new ones from Ebay, and after that, the drive works perfectly! It used to only spin sometimes, and when it did spin, it was incredibly unreliable. That is because the sensors are needed to regulate the speed of the motor properly, and with one or more failed, it was no longer able to do that. With the floppy drive working, the next issue is to find why the analog board is not allowing audio to pass through to the speaker properly. This machine is waiting in line to get a full restoration (new capacitors and other maintenance done), but in the meantime, at least it has a working disk drive. Updated 11/06/2025
Apple IIc - February 20, 2025
Not much to say for this machine, as it has worked ever since I got it. I bought it with the power brick, main unit, and a very rough IIc monitor, which I have since sold. It is a cool little system, and has the ALPS keyboard, so it is amazing to type on. I am hoping to get a small LCD monitor set up with it and a USB-C power solution to make it more portable. Updated 11/06/2025
Sun SparcServer 20 - December 6, 2024
This is my second UNIX machine that I have picked up. It came with two processor cards, no frame buffer, and no hard drives, as it was set up to run as a server rather than a workstation. I have since acquired a Sun keyboard, mouse, and frame buffer card, as well as the proper hard drives and display adapter to make it all usable. One of the processors and one of the RAM modules ended up being faulty, so they have since been removed and the machine now works great on one processor. It is currently running Solaris 2.6. Updated 8/15/2025
Apple Network Server 500/132 - October 4, 2024
This was a very special machine for me to acquire. It has been my introduction into the world of UNIX (which I now find very cool, especially AIX!). It is fully operational, running AIX 4.1.5 on a 9Gb hard drive. When I first got it, it was running on its 2Gb IBM hard drive. I have learned a lot from working on it, and will continue to work on it in the future. It is on the list to get a recapping soon so it continues to be reliable, and the hope is to eventually make it available for public login! Updated 8/14/2025
Apple IIe Systems x2 - September 15, 2024
I acquired both of these systems at the same time, and remarkably, both just worked. I replaced the RIFA filter capacitors in both power supplies, and sold one machine to make back some of the cost of the lot, but I still have the second one and it works great. The disk drives have had their heads cleaned and have been tested, all four drives worked. I am very impressed with the build quality of the Apple IIe, no wonder they were sold for so long! Updated 8/14/2025
Macintosh Classic and Classic II - August 6, 2024
These two machines were given to me as a pair, and neither one worked when I acquired them. They have since been both fully recapped, the Classic needed some bodge wires on the logic board and a new optoisolator on the analog board, and the Classic II had its logic board sent out for processor replacement. Both are now fully operational and will stay around as part of my compact Macintosh set. Updated 8/14/2025
Macintosh 128k - April 5, 2024
This is the second vintage Macintosh I have acquired. It is a Macintosh 128k that was upgraded to 512k of RAM on the logic board, had a Dove MacSnap RAM upgrade, and an 800k floppy disk drive. The Mac needed some work, I had to remove the RAM upgrade board because it had a fault and had to change a few capacitors on the logic board. The internal frame has also been sandblasted to remove the corrosion. This is a neat machine, but likely won't be with me long term. The floppy disk drive was the worst I have ever worked on, but it is now fully operational and may actually be one of my most reliable drives. The display is quite nice and bright with minimal burn in. Updated 8/14/2025
Toshiba T3200SX - March 27, 2024
This is my first vintage PC. It is a Toshiba T3200SX with an Intel 386 processor. It came to me without a hard drive, and I had to purchase a replacement ROM to allow it to use another hard drive other than the specified Conner hard disks in the bios. Once it got the new ROM and a CF to IDE replacement hard drive, the machine worked great. The gas plasma display is nice and bright and works well. It is currently running DOS 5.0 with Windows 3.1, and makes an awesome Tetris machine. Updated 8/14/2025
Macintosh SE Superdrive - February 19, 2024
This is my very first vintage computer. I purchased it from the original owner, who said it had worked just a few days before I picked it up. By the time we bought it, the internal Maxell battery had exploded and destroyed much of the logic board, but we were determined to make it run again. I eventually got the machine running on its original logic board, but I decided to replace it anyways for sake of reliability in the future. The machine is now fully recapped and serviced, and gets a good amount of use thanks to the BlueSCSI V2 giving it a new hard drive and networking capabilities. I use it quite a bit to telnet to my server and even view my website. Updated 8/14/2025
