== Amstrad's implementation of CP/M+ ==
Amstrad distributed CP/M+ on the side 4 of the system discs that came with the CPC6128. It requires a Dk'Tronics compatible ram expansion. It provided 61K TPA. CPM+ doesn't use the firmware. To get 61K TPA, CPM+ uses 'C1' RAM configuration with most of the code in the 2nd bank of 64KB leaving almost all the 1st bank of 64KB useable for programs.
On side 1 of the system discs was CP/M 2.2.
