48kB RAM (later models with 56kB or 64kB), 4kB ROM (later model with 8kB). Standard QWERTY keyboard, TV OUT 288×256 monochrome graphics, 25 lines, 48 characters. The last model can use 8 colors, the first model only 4: black, white, gray and flashing). Tape deck as storage. 1-bit beeper. Two parallel ports, serial port (8251). It uses a ROM cartridge with BASIC (you can also buy Pascal later).
One Slovak collector has a PMD-85-1 "clone" in his collection and shared the information:
"The initiative at ZVT Banská Bystrica was quite interesting. Maybe up to 40 pieces were produced there as a side project, which they called a "display unit". " or amateurs on universal boards. My opinion is that they covered it up in production so that they could make boards. Anyway, I have two "ZVT" keyboards from PP01 :) . And I know of two other surviving pieces. More modern components were used there, for example, 2764 or even 27128 type."
