Mr. Stanislaw Gardynik, who was the architect of CA80 and owner of MIK company, managed to design and develop CA80 and full documentation by his own. He was employee of Polish Academy of Science (PAN - Polska Akademia Nauk) with very good background in electronics and computer science.
The adverts of CA80 kit were available in electronic and computer magazines. I still have a catalogue/leaflet that briefly describes the whole idea of Mr. Stanislaw:
"The educational controller CA80 and literature from MIK series are mainly targeting the people who "don't know the Ohm's law". Each year arrive around 500k of new potential users of CA80 - that's the number of young people ending primary school.
Documentation of CA80 assumes, that user can read and think logically - no basic knowledge of electronic or microelectronics is required. CA80 is the DIY microcomputer, therefore it's documentation starts from terms like Voltage, Current, Ohm's law and ends ... with interrupt system, emulator. Basic documentation it's a essence of knowledge about electronics and microelectronics. Understanding of MIK1 to MIK04 guarantees the passage of certain knowledge level, above which contact with microprocessor tech became joy and enables further effective self-education.
Each newbie programmer (I went through this by myself as well - says author) generates big number of "simple" errors. Only after years, he will reach a few errors per each 2kB of machine code and became professional programmer.
Due to above the most important, for newbie programmer, are best tools to run programs on full speed in target environment.
This type of tools are delivered by CA80!!!"
I've bought my first set of MIK documentation (MIK01 and MIK02) in early 90's, when I was 16 year old. Together with MIK03 and MIK04 those were forming the ABC and basic courses of electronics, microelectronics and digital gates. The logic state probe and simple breadboard with books and supplementary catalogues are presented on photos bellow.
