yeah, it came a bit late for me as i had already got my hands on what was the best ca 1983, the mighty c64. Probably would have gotten the amstrad if it had come out earlier. Very very popular machine, it became.

I have two of these; one has been converted to a 6128 with a chip swap and memory pack. The membrane keyboards were immensely troublesome - I got fed up of dismantling and cleaning them.
Box-loads of games and apps. Have an original copy of the complete op code.
Also have a refurbished 464 and a modulator.
The graphics gives one a pounding headache! Would like to upgrade. Amstrad was destroyed by the Yanks, WD & co., who were extremely worried about cheap Asian imports under-cutting their home market - now look where we are!!

This was the first ‘serious’ computer I owned – serious because it could run CP/M and therefore I could write useful software in Turbo Pascal and dBase II, and It also ran Wordstar. I don’t think it fair to call the monitor ‘mediocre’ – remember everyone else, with Spectrums, C64’s and so on, plugged their machine into the TV, and the Amstrad monitor was certainly better than that. I had the 12” green screen which was perfectly good enough for working at. I was also rather glad I bought it before it was replaced with the 6128, which had a pretty horrid keyboard - the 664 had a really nice keyboard!
One problem though was that because the screen was bitmapped it ate 16K out of the 64K memory, leaving an unusually small TPA for CP/M, of around 45K (I can’t remember exactly, but the 42K cited on the 6128 page doesn’t sound right – but perhaps my memory is faulty). Most CP/M machines had character mapped displays which only used about 2K. Eventually I bought a 64 Ram expansion and got a copy of CP/M3 (aka CP/M +) (as used on the 6128). This expanded the TPA to 61K – and I added an external 5.25” drive which held something around 880K – a vast amount I never thought I’d fill…
