UT-88

The UT-88 (ЮТ-88) is a DIY educational computer designed in the Soviet Union. Its description was published in YT dlya umelykh ruk (Young technical designer for skilled hands, ЮТ для умелых рук) — a supplement to Yunij Technik (Young technical designer, Юный техник) magazine in 1989. It was intended for building by school children of extracurricular hobby groups at Pioneers Palaces.

Description
At the time of publication, there were several DIY computers: Micro-80, Radio-86RK, and Specialist. The main feature of UT-88 was the possibility to build a computer in stages while getting a workable construction at each step. This approach made it easier to build by less skilled hobbyists.

The minimal configuration of the computer includes a power supply, CPU, 1 KiB of ROM and 1 KiB of RAM, 6 seven-segment displays, a 17-key keyboard, and a tape interface. This computer can be used as a scientific calculator.

Full configuration adds a display module    with a TV interface, a full keyboard, and a 64 KiB dynamic RAM module.
