IPT-002 ("Kompi") microcomputer

• programming simpler calculations
• (for the time) simple games to run

Structure

Central unit

Byte-organized (8 bpB) machine

• control unit:Zilog Z80electronic circuits built around a microprocessor
  • clock speed: 2.5 MHz
• main store:
  • 16 KB DRAM
  • 12 KB EPROM
• calculator: ALU built into microprocessor

Periphery

• backup:
  • (cassette) tape recorder (optional)
  • floppy disk (optional)
• External units:
  • keyboard
  • standard TV set (instead of a monitor)
  • simple sound generator
  • character printer (optional)
  • interface circuits
    • standard V24 serial interface
    • Centronics parallel interface (optional)

The machine also came with a separate power supply

Operation

After turning it on, BASIC started automatically, so you could immediately perform calculations in interpreter mode, or write programs and then run them immediately.

If available, programs could also be saved to tape; stored programs could be loaded and run again using the built-in search program.

There was a (difficult) option (PEEK/POKE instruction pair) for writing machine code functions and incorporating them into BASIC programs.

Screen resolution: text only mode, 32 lines 24 chpl.

Program set

• there was no operating system
• compiler: BASIC

By using the assembler written for the Sinclair Spektrum and rewriting the monitor program written for the HT1080Z, it was possible to run programs written in machine code.

By merging some characters – with some programming – they created a 64*48 pixel “quasi” graphic.

Programs written for the sound generator of the tape recorder interface allowed simple melodies to be "strummed"

50 games, mathematics, statistics, electrical engineering and computer science programs were available for purchase separately on cassette.

Historical curiosities

It is a strange curiosity that the machine came with a significantly oversized power supply, the size of which was almost twice the size of the keyboard containing the central unit.

The Triton cooperative unsuccessfully applied for the IPT-002 computer in the School Computer Program, after which it stopped production and sold the completed copies under the name Kompi at a discount price.

Kompi did not play a significant role in the domestic IT industry – it was included in the Database only as a historical curiosity, to prove that in the early 1980s, the IT developments of domestic SMEs reached European standards. Unfortunately, due to limited parts procurement opportunities due to the industrial and economic embargo, as well as currency restrictions, they gradually fell behind in the intensifying competition and were thus forced out of the markets.
