ZX Spectrum
Spectrum
<computer> {Sinclair}'s first personal computer with a colour
display. The Spectrum used the {Zilog Z80} processor like its
predecessors the {ZX-80} and {ZX-81}. It was originally
available in 16k and 48k versions using cassette tape and
later grew to 128k and sprouted {floppy disks}. It had a
wider and more solid case and a marginally better "dead flesh"
keyboard. Unlike the earlier models, it didn't require the
presence of a cold carton of milk to prevent it overheating.
It was possibly the most popular home computer in the UK for
many years.
The {TK-90X} was a clone.
