The PMD 85 was an 8-bit personal computer produced from 1985 by the companies Tesla Piešťany and Bratislava in the former Czechoslovakia. They were deployed ''en masse'' in schools throughout Slovakia, while the IQ 151 performed a similar role in Czech part of the country. This computer was produced locally due to a lack of foreign currency with which to buy systems from the West. After the Velvet Revolution in 1989, production of the PMD 85 was stopped. PMD 85 was not competitive in quality or features compared to foreign PCs available at that time. ==Specifications== * MHB8080A 2.048MHz CPU * 48 KiB RWM (PMD 85-2A and 3, 64 KiB) * 4 KiB ROM (PMD 85-3, 8 KiB) * System monitor * Tape utilities * TV output (B/W, PMD 85-3 PAL) or RGB component video * 288×256 resolution * 4-level attribute (flickering, grayscale or colours, depending on model), selectable per 6 pixel wide stripes * Tape recorder interface * IRPS interface (passive current loop RS-232 without modem control signals) * Module interface. A ROM module with the BASIC programming language was a standard part of the computer, but there were more ROM modules containing Pascal, Assembler, LOGO etc. Available were also programmer. * IMS-2 interface (non-standard connector and electrically partially non-conforming) based on MHB8255A * Two 8-bit parallel buses supporting handshaking (via second MHB8255A) * Application connector (de facto system I/O bus) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PMD 85」の詳細全文を読む スポンサード リンク
