Arnd Menge wrote that code, but as I recall, it has to get a byte on or off the disk in less than 32 cpu cycles (possibly ~64 in 2MHz mode), so I believe it was tuned how it needed to be to replace the parallel cable. I doubt it could be slowed down... -Pete Rittwage Message was sent through the cbm-hackers mailing listReceived on 2014-04-26 03:00:46
