CPM 3.0 (also known as CPM+) was available on the 2nd [[System_DiskSystem Disk]] Disc for CPC6128 but there were other implementations available.
== Dobbertin's implementation of CP/M+ ==
ESC A - cursor up
ESC B - cursor down
ESC C - cursor leftright ESC D - cursor rightleft
ESC E - clear screen and move cursor to home
ESC H - move cursor to home
=== Extra memory ===
CPM+ on the CPC uses 128KB of memory. Therefore selections C4,C5,C6,C7 must be avoided if you have additional memory. Due to the design of DkTronic's compatible RAM expansions all memory accesses to additional RAM must occur from bank 0 (i.e. 'C0C1') and be transferred to the TPA in bank 1 (i.e. 'C2').
Therefore access to the additional RAM follows a pattern such as this:
