Correct me if I am wrong, but I think the time out error results from the following: The FDC waits for the index hole, then looks for the given sector. If the sector is not found before the index hole comes around again, a time out error occurs. This is my conclusion based on reading the 8272 data sheet, and experiences (at present) trying to get my PC to read old CP/M Microbee disks, which have sector 1 placed so soon after the index hole that PC's have trouble reading it. If you find out a way around the 'time out' problem please tell me! -- Russell Lang Email: rjl@fawlty4.eng.monash.edu.au Phone: (03) 565 3460 Department of Electrical and Computer Systems Engineering Monash University, Australia -- Russell Lang Email: rjl@fawlty4.eng.monash.edu.au Phone: (03) 565 3460 Department of Electrical and Computer Systems Engineering Monash University, Australia
