The mainboard contained only CPU, supporting ICs and memory. Everything else was added by expansion modules, with five available slots.[6][7]
Like mentioned above, elementary expansion modules are Basic 6, a BASIC language interpreter and Video 32, a video generator, producing 32 columns and 32 rows of text and semigraphic characters.
Advanced expansion modules include Video 64, allowing 64 x 32 character text display; Grafik, adding true 512 x 256 monochromatic graphics and Basic G, with additional graphical functions to BASIC; Pascal, and editor and compiler of the PASCAL programming language; Assembler, a low level programming language; AD/DA, a ADC / DAC converter interface; MS 151 and MINIGRAPH, a drivers for Czechoslovak plottersXY4130 and Aritma 0507; STAPPER, a driver for a punched tape unit; SESTYK, adding a serial port for networking and DISC 2, acontroller for a 8" floppy drive using on an unlicensed CP/M clone. Due to an EPROM address conflict, DISC 2 couldn't be used with the Basic G or Pascal modules.
It IQ 151 was primarily used in Czech schools, while in Slovakia the PMD 85 series was used instead.[5][8] This computer was produced locally due to a lack of foreign currency with which to buy systems from the West.[citation needed]
This computer had a persistent tendency to overheat under even a light workload and thus the common joke about it was "it's an excellent coffee mug heater." It also had a poor membrane in its keyboard, in comparison with slightly more advanced PMD 85.
After the fall of Communism in 1989, production of the IQ 151 was stopped, since it was not competitive in terms of price, quality or features compared to more modern computers.
