That's very interesting. So this was a modern SFD1001 without the ieee interface? Did anyone know more about the floppy controller chip MOS 8723? > Only I've never > seen a 6508 in any CBM drives - usually 2x6502, 6504 and other > 650x'es etc... The 2040/3040/4040 use the pair 6502/6504. The later version 8050/8250/1001 use two 6502. No other CPUs are used. But why don't use a 6508 with some ram and io? So the disk controller system (one cpu) from the cbm floppy drives can be implementated. That's very interesting... > I'll put up some photos some day - I just need to get a little further > in the process. That would by great. What's the history from this C900? Is it a workstation or server model? Greetings Martin Message was sent through the cbm-hackers mailing listReceived on 2011-10-29 00:00:08
