So if you wish go this route, why not get rid of the second CPU altogether and make something like the CBM-II low cost drives which were driven by the computer's CPU?

My theory was that by bypassing that 'serialization', the very same set of commands sent to the drive could be used. > > Regards, > Michau. > > >Received on 2022-03-30 14:00:42
