To set the record straight, I'm an Electrical Engineer (Computer Systems) which I would hardly describe as non-technical :-) >drives are that way because they use a 500KHz clocking frequency, the >Amiga can only generate a 250Khz bit rate clock. Sorry you lose. Read >up on disk electronics (good references are early issues of BYTE or >Kilobaud Computing which talk about 8" floppies that also use 500khz [stuff deleted] Why can't I use an external buffer/500 kHz bit rate sync circuit? Thats what my 8 bit HD Floppy controller does thats sitting in my PC. Granted, it's more involved than simply plugging in a drive and using it but it's certainly not impossible.
