KeyRus was a DOS-based TSR device driver for keyboard and display, written by the Donetsk student and hacker Dmitry Gurtyak [uk] in 1989. It was widely distributed in the USSR and outside of the country free of charge. The last version of KeyRus was released in 1994. Gurtyak died in 1998 of a soft tissue sarcoma at 27 years of age.

KeyRus was distributed primarily via electronic bulletin boards and Nikolai Bezroukov's Softpanorama electronic magazine. It loaded fonts into the EGA/VGA and supported changes to be keyboard layout. Initially, it could change only between the Russian and Latin keyboard layouts, but later became more configurable.[citation needed] Its distribution included layout and font editors.[1]

Later versions of KeyRus utilized an original font compression technique - the bitmaps were stored in memory being packed and unpacked just before loading into the graphics adapter. This allowed KeyRus to occupy a minimum of the limited DOS memory space.
