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 He doesn't remember much of what he used it for, but he did have the original manual, which has now been archived!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
