We are trying to read some floppy disk used on a 1981 Italian Z80 machine with CP / M. The problem is that the firmware selects face A of the floppy as DRIVE A and face B of the same floppy as Drive B. We saved an image with IMD and we know that the geometry of face A is IBM 3740 26x128x77 tracks. By inserting this data into the 22DISK definition file we can successfully extract the CP / M files from A side. How should we configure 22disk to be able to do the same thing on the B side of the same floppy disk? Inserting Side 2 in the definition table is not enough .... Thanks Enrico - Pisa- Italy
