PMD-85-0
Designed by Ing. Roman Kišš.It was manufactured from 1983 to 1984 (prototype 1982, show 1983) by Tesla Piešťany. The computer was inspired by or was successor to HP 85. Hardware is based on MHB8080A @ 2.048 MHz.
It is not a copy of the HP85, only "ideological inspiration pattern". It is therefore not a complete plagiarism, as was otherwise common.
Inherited software:
G-Basic for PMD-85-Microsoft Basic for NASCOM
Roman Kišš's lectures show that the functional prototype of the PMD-85, or at least part of it, including a solution for dynamic RAM and cooperation between CPU and videop, built during Christmas in 1982.
At the exhibition in 1983 in Prague, the PMD-85 was first introduced. This model then appeared at the exhibition in 1984 in Bratislava. According to available information, 220 PMD-85 pieces were produced in 1983, which at that time was considered "the first personal computer in Czechoslovakia produced in larger quantities", as the editor said.
