Memotech were one of many companies who sold third party ram-packs, ‘real’ keyboards and other accessories for the Sinclair ZX81. As their design for ram packs eliminated the wobble that Sinclair’s official packs suffered from and came in a range of sizes up to a then whopping 64k, Memotech’s peripherals proved popular, especially at the more serious end of the market.

After seeing the Spectrum, Memotech felt the time was right to launch a well-specified computer for home and small business to take advantage of the respect that the company had built up during the ram pack years. Various models of the MTX were released, including the 128k RS128, but software support was largely limited to the in-house Continental Software and smaller third party companies, which meant that the Memotech never gained wide acceptance.

The Games

Various games were produced in house by Continental Software, including PotHole Pete. Megastar Games also released about 15 titles for the MTX.

Trivia

An MTX512 and FDX can be seen in the film Weird Science as the computer boys use to generate a virtual Kelly LeBrock.

Many video walls seen in shopping centres throughout the late eighties were driven by adapted Memotech RS128s.
