I remember when a friend got a disk drive, and it was the 1541C. ok, then out of curiosity, if anyone happens to know: why only 1541C seeks to track 1 at reset? > > Are you sure that it wants to read from the disk?

Reading from the disk > should involve seeking to track 18 to read the directory. no it does not seek to track 18, but if I read the error channel after reset, it gives an error 20 (without the error light flashing though),but I didn't record on what track/sector.

I'll check the CLK and DATA inputs on the 6522 and see what it thinks they are at reset. Thanks Frank Message was sent through the cbm-hackers mailing listReceived on 2018-01-14 17:00:03
