Mine is the older 3-1/2” chassis that had actual lights and switches on the front panel, and it was designed to work with the older 6902 CPUTTY card instead. I was thinking about laying out and building my own CPU card for it, and I’d like to include the 6102 MEDIC in that design so that I can have 32k of memory. I have schematics for the 6912 card (they’re in the manual) but no firmware binary or source listing, and that’s why I’m interested.
Bob, we have an Intercept III system at LSSM, does that use the same
CPU board? If so, we should be able to dump those ROMs.
