@keyboards On the "what the 1982 market demanded, only in 1984" note, Amstrad was a consumer electronics firm and Alan Sugar was not a computer guy—he hired the design talent in and bought the components obsolescent hence cheap (eg. his giant bulk buy of Sony's also-ran 3" floppy disks and drives—he bought their entire manufacturing run when it failed to out-compete the rival 3.5" standard). I think he lacked a feel for the pace of change in computing, which was much faster than in TV/audio.
