ZX 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.
