This page describes Vorteximplemented their own version of CP/M for the CPC and also provided patches for Amstrad's CP/M to use their memory expansion. There were also third party implementations which supported the Vortex RAM Expansion such as [[RCPM]]. == Vortex's 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 implementation of CP/M2.2, 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 CCP/PM M you need:1. * a CPC4642. * VDOS 1.0 on ROMand a Vortex disc interface.3. * a 80 track double sided drive A.4. * 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.
