Re: Gemini 80-Bus System
The GM813 has 64k Ram on it.
Try replacing the MAP80(ram) and the GM811(cpu) card in the rack system with the GM813 card from the MFB system. This should be able to run RP/M as before with the GM832(SVC) or GM812(IVC) Video card.
Depending on if this works or not will give you some useful information.
You should also be able to try the GM849 from the MFB system as a replacement for the GM829 card in your rack system. This should at least attempt to boot from the floppy disk although you might need a slightly different version of CP/M to work properly. As a personal favour if you get this combo running would you like to run my basic program posted above and post the output so I can complete my MFB system emulation.
Best wishes
John
