From my notes: "EXTSYSMM.IMD is a bootable diskette, single-sided, 9X1024 with Mark Zeiger's personal files removed and MCLBIOS.ASM and MCLBIOS.BIN added to User 1. MCLBIOS.ASM is the CBIOS source for console on the DJ 2D/B serial port." Let me know how it works for you. Mike Loewen Old Technology http://q7.neurotica.com/Oldtech/
