Changes
/* Vortex's implementation of CP/M on Floppy */
Vortex implemented 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 CP/M 2.2, which came with the CPC664 , so it 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:
* a CPC464
* VDOS 1.0 on ROM and a Vortex disc interface.
* a Vortex 512KB RAM Expansion.
== 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.
