Vortex CP/M

Vortex provided patches for CP/M 2.2 to enable using their memory expansions and floppy disc drives. Vortex also provided an already patched version of CP/M together with the X-Drives.

Patch for CP/M 2.2 to use 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.
