About: PMI-80

An Entity of Type: information appliance, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The PMI-80 was a single-board microcomputer produced by Tesla Piešťany, Czechoslovakia, since 1982. It was based on the MHB 8080A CPU (a Tesla clone of the Intel 8080), clocked at 1.111 MHz. Instead of a raster graphic display output and classical keyboard, it had a calculator-style nine-digit seven-segment red LED display and a 25-key calculator-type keypad with hexadecimal and function keys (including hardware REset and Interrupt). The PMI-80 had 1 KiB of ROM (expandable to 2 KiB) and fixed 1 KiB of RWM. Eight (expandable to 32) I/O lines were provided for user along with complete system bus. Connected could be e.g., a card with a DAC of 0–12 V range.

dbo:abstract
  • PMI-80 byl jednoduchý jednodeskový mikropočítač vyráběný od roku 1982 firmou Tesla Piešťany v bývalém Československu. Měl jednoduchý LED displej o 9 znacích a 25 kláves. Používal procesor Tesla MHB 8080 (klon Intel 8080) taktovaný na frekvenci 1,11 MHz (10/9) a měl 1 kB paměti RAM i ROM. Byl určen pro výuku programování na středních elektrotechnických školách i polytechnických univerzitách. Používal se také k jednodušším řídícím aplikacím v průmyslu. (cs)
