The UT-88 () is a DIY educational computer designed in Soviet Union. Its description was published in YT dlya umelykh ruk (Young technical designer for skilled hands, ) — a supplement to Yunij Technik (Young technical designer, ) 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, 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 power supply, CPU, 1 KiB of ROM and 1 KiB of RAM, 6 seven-segment displays, 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 and a full keyboard, and a 64 KiB dynamic RAM module.
