Memotech Limited was a British computer company founded by Geoff Boyd and Robert Branton in Witney in Oxfordshire, England. They started out during the early 1980s producing memory expansion packs ("RAMpacks") and other hardware expansions for the Sinclair ZX81. However, they eventually went on to develop and sell their own MTX family of computers in 1983. The range included the following models: MTX500, MTX512 and RS128. The MTX 512 was based on the Zilog Z80 processor. Although well-regarded, these computers were not commercially successful, and the company went into receivership in 1985.
