Hallo, I know there has been some discussion about how you can tell a 8250 to go into the 8050 mode. But what I don't know (missed, forgot) is how a 8250 recognizes if it is dealing with an 8050 or an 8250 formatted disk. AFAIK that it simply expects to read a 8250-disk and if it isn't, returns a read-error. The reason while I'm asking this is the fact that I'm devolloping the part of a program which enables you to creat disk-images. I noticed that byte 3 of T/S 18/0 was $80 for a 1571-disk indicating a double sided disk (0 for a 1541). Then I noticed that there was no difference in the directory headers of a 8050 or 8250-disk. So how is a disk recognized? IMHO there is a neat way to find out if a 8250 is dealing with a 8050-disk or not by reading the first two bytes of second BAM-block. $27/$01 means an 8050-disk, $26/$06 means an 8250-disk. The question is does the 8250 use this as well? Groetjes, Ruud - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail email@example.com.
