Vortex provided a patched version of CP/M 2.2 together with their F1/M1 drives. After a legal dispute with Digital Research, Vortex only provided patches for CP/M 2.2 to enable using their memory expansions and floppy disc drives.
Patch for CP/M 2.2 to enable Vortex RAM Expansion
Vortex provided a disc with a PATCH.COM on it which patched Amstrad's CP/M 2.2, which came with the CPC664, so that CPM could use their RAM expansion to get 63KB TPA.
Vortex's implementation of CP/M on Floppy
To boot CP/M you need:
- a CPC464
- VDOS 1.0 on ROM and a Vortex disc interface.
- a 80 track double sided drive A.
- a Vortex 512KB RAM Expansion.
There are other versions of VDOS and other ways to boot their CPM on CPC6128 etc.
Vortex's implementation of CP/M on Vortex's Winchester WD20 hard disk
Vortex's CP/M for their hard disk is CPM2.2 only.
