Or do you want to create a completely new drive, perhaps in the style of C65's internal dumb drive or CBM-II's planned low cost disk drive? It's still a sort of "remix" of existing technologies. Taking internals out of drives and putting them in a modded case with the C64. > > For connecting a 1541, yes you can create a PCB to piggyback on the CIA socket but not all C64's have socketed CIAs. I was wondering if is there anyway to take the serial protocol out of the communication between a C64 and a "not dumb" CBM drive and make both talk about DMA. There is a CBM drive already doing that, isn't it? One for the PLUS4 series, I think... > > Regards, > Michau. >Received on 2022-03-28 17:00:07
