Memotech RS128

The Memotech RS-128 S2 was an upgraded MTX-512 with 128KByte of RAM

The Memotech MTX computer line

The Memotech MTX computers came in an all aluminium case with a full sized keyboard and full-stroke keys. Built in was a BASIC interpereter with rudimentary windowing and LOGO command support. The system had cartridge support and could be expanded by an FDX system, which added 5.25" Floppy disk drives, Winchester hard disks using the CP/M 2.2 OS. The FDX expansion was very expensive.

In 1984 Memotech was working on a project to deliver the MTX-512 combined with the FDX and an I/O control system developed by Norbit Elektronikk Norge, to 64000 schools across the Soviet Union. At the time the Soviet Union was prohibited to buy IBM Personal Computers from the US, but CP/M computers were not part of the embargo.

Memotech made a substantial investment in order to prepare the deal for the Soviets. A special red case was designed and manufactured in The Netherlands, BASIC, character encoding, manuals, and keyboard all had to be adapted to the Russian language and character set. As a result Memotech required the USSR cash payments prior to the delivery of the computers. The Soviets decided against this, and bought MSX computers from Yamaha and Daewoo instead. The deal fell through for Memotech and the company went bankrupt
