There were also some pretty high-spec British microcomputers, but they
tended to flop owing to the price. Things like the HH Tiger (did it
ever go into production? Prototypes certainly exist).

My experience at the time was that CP/M was not a 'big thing' in
Britain. And S100 was even less. Yes there were S100 computers here
(there were some British-produced ones like the CASU Super C which
used bought-in CPU and RAM cards and CASU I/O cards) but I don't
really remember them at the time.

Although it is worth remembering that before the BBC micro, schools
sometimes had Research Machines computers (there were some at the
school I went to). The RML380Z did use CP/M. But I suspect that the
BBC micro ended up in many more schools that the RMLs did.

Which were those? I thought all the Amstrad disk-based CPCs and PCWs
could run CP/M
