Slap me on the back of my head ;-) I meant U2 of course. My small Basic/ML programs "disk2file" and "file2dsk" for the PET and C64 use exactly the same ILLEGAL TRACK OR SECTOR trick to dump/restore any CBM disk image. However, I had to implement a check for track 78 or so because reading an 8050 (single sided) disk on a 8250 (double sided) drive gives a READ ERROR but no ILLEGAL TRACK OR SECTOR. BTW, I uploaded those prgs to funet, where did they end up? Andre -- Email address may be invalid.
