Even > some original CP/M disks appear to be single sided. The C128 were shipped with a CP/M disk that were usable in a 1541. Back in the days I had a 128 with a 1541 and I remember that I booted CP/M. However it took soooo much time to do anything due to the bad disk performance so I never used it for anything interesting. The fact that no programming tools (afaik) för CP/M were shipped with C128 didn't help either. IIRC the disk that shipped with C128 were a flippy. Thus you should probably have two D64 images from that disk. Remember that when the C128 started to ship there were afaik no new disk drives. It took a while for the 1570 to be in the shops, and the 1571 took even longer. Therefore the disk with C128 CP/M must have been 1541 GCR compatible. Re CP/M disks - it would probably be a good idea to add D64, D71 e.t.c. support to some already existing application that's used to manipulate/read CP/M disk images. IMHO Commodore were bad at providing the kind of required transfer software. Not only did C128 not ship with some transfer program for moving data between CP/M and CBM disks, but on Amiga in Workbench 1.3 (and possibly also 1.2) there were a program included to read/write ms-dos diskettes, but it were hardcoded to use the third drive and afaik also hardcoded to use a 40 track (360k) drive, making the program useless to most users.
