<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. (1995-11-04)
