== Amstrad's implementation of CP/M+ ==* Amstrad CP/M+ uses Amstrad's "System" format. This is 40 tracks, 1 side, 9 sectors per track numbered &41-&49. There are two reserved tracks, then the directory which has 64 entries, and then the data area.
Amstrad distributed CP/M+ on the side 4 of the system discs that came with the CPC6128.
On side 1 was CP/M 2.2.
* Amstrad CP/M+ uses Amstrad's "System" format. This is 40 tracks, 1 side, 9 sectors per track numbered &41-&49. There are two reserved tracks, then the directory which has 64 entries, and then the data area.
* CP/M is booted using an RSX command "|CPM" which is implemented in the Amstrad disc rom (AMSDOS).
* |CPM loads track 0, side 0, sector &41 into RAM at &100-&2ff. This is the boot sector and contains the boot program.
