The MUPID (short for "Mehrzweck Universell Programmierbarer Intelligenter Decoder" in German) or MUPID A320 was an early home computer like system introduced in 1981, designed and invented by Hermann Maurer at TU Graz, Austria[1] to be used as a Bildschirmtext terminal, but it was also capable of being used as a stand-alone computer.[2]

SuccessorMUPID II

It had a Zilog Z80 microprocessor and came with BASIC as operating system, 128 KB of RAM, a V.24 1200/75 baud modem, audio input/output for tape recorder, a parallel printer interface and an optional external floppy drive unit. At the time it excelled in having advanced color graphic capabilities.[3]

There were several model variations: the MUPID C2D (square case with separate keyboard) and MUPID C2D2 were available in Germany, the MUPID C2A2 or "Komfort MUPID" (later models) were available in Austria.[3]

The Mupid was also sold under other brands, as the Grundig PTC 100 (C2D2 variation in a different color) and the Siemens T3110 (C2D variation).[3]

A card for older IBM PC compatibles with an ISA slot was developed that gave a PC the same graphics capabilities as a MUPID.[4]

The original Mupid A320 was followed in 1983 by the MUPID II.[1] This version supported the CEPT Prestel standard, had a better keyboard, a 320 × 240 graphics mode, four voice sound, two DIN6 joystick connectors, a DIN8 tape interface, a DB25 modem, a DE9 serial connector and a DIN8 external disk drive connector.[5]
