The original Vector Graphic CP/M 2.2 distribution disk image is CPM22-56K-DSDD (original).DSK.

The original disk with file transfer utilities (PCGET, PCPUT), disk image transfer (PC2FLOP, FLOP2PC) and a few other programs added is CPM22-56K-DSDD.DSK.

Use PC2FLOP in the disk image transfer directory to create a disk, even on a "cold" machine.
