Modifications

There were three computer modifications: with a domestic display module based on the IZhG93-640x200 LCD matrix manufactured by the Saratov Electronic Plant "Reflector", as well as with compatible display modules from Toshiba and Citizen. Each of these modifications had two versions: with a display without backlighting (green screen - black characters) and with backlighting (blue screen - white characters), both with adjustable contrast. Externally, the backlit version was distinguished by a thicker cover and a smaller screen diagonal.
