UK "Home micros" with a Z80 (ZX Spectrum, Amstrad CPCs, ...) where not shipped with CP/M, although you could probably run it. Did this (in an emulator) with the CPC . > 6502s were for hobbyists writing in basic and assembler. The UK market (and that's what we're talking here about) saw more Z80 based ZX (Spectrum, 81/80) machines that Commodore 64s. But the UK saw also a big number of Acorn computers, which ran a 6502. Those, like Apple 2s, were rather expensive that they were mainly used in the education sector. If you check some links of it can be noticed that most of the used a Z80. > As for 6809s - great chip. No one really used it. The TRS color computer and "clone" Dragon 32/64 did. Latter also sold in numbers.

Wasn't Apple II a 6502 as well? Yes, but at least in Europe to expensive for the common user. Outside the UK most got a C64, while in the UK Spectrums ruled the market.
