ZX Spectrum
Jump to user comments
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.
