I know its offtopic and we all love to hate apple, but I read some interesting information in a hardware reference book. There's a GCR nybble exactly every 32 cycles. There's no byte ready line or other hint that a nybble was read. Just read, and -exactly- 32 cycles later, read again or miss a nybble. :) The 1541 uses a variable bit clock, so it can vary, but the smallest sector count matches the evil system at 16/track, so it's probably not far off. ;-) -jbevren On Fri, 11 Nov 2005 firstname.lastname@example.org wrote: > > On 2005-11-08, at 10:33, MagerValp wrote: > > > > > No, there aren't enough cycles to decode to nybbles in realtime, > > Could you remind me how many of them are there in the worst case? > > -- > Apple products look like they come from designers that Ikea wish they > could afford. - Ian Brogan > > > Message was sent through the cbm-hackers mailing list > Message was sent through the cbm-hackers mailing list
