In 1985 CoCom, organization controlling export of military tech and assessing possibility of using specific civilian technologies for military purposes, relaxed rules allowing 8-bit computers to go thru.

Still all computers with a power exceeding 8 bits, software for computer-aided design and manufacturing (CAD/CAM), software related to sound and image processing and artificial intelligence, as well as software used for testing computer technology were still strictly prohibited.
There were personal computers in Poland before 1985, all smuggled and illegal. Just like owning Dollars, Deutsche Marks and Pounds was illegal yet there was whole chain of official Pewex shops accepting exclusively those currencies. Poland was weird like that.
Klaudiusz Dybowski was chief of Commodore corner in Bajtek. Interview:

50:40 timestamp is where he talks how he got his own Commodore 64 into Poland in late 1984 https://www.youtube.com/watch?v=7IC7zYjrSxo&t=3043
>"natomiast Musiałem zostawić sprzęt w urzedzie celnym, bo zglosilem ze przywiozlem komputer, "musi pan to zostawic, teraz musi pan napisac podanie o zezwolenie na posiadanie komputera i wwiezienie go do Polski", i mam to podanie, napisalem je, mam do tego [....] od Zarządu Ruchu Lotniczego i Lotnisk Komunikacyjnych dostalem takie poparcie "bardzo prosimy zeby mozna to bylo wwiesc, komputer bedzie sluzyl do obliczen prodedur itd" i to zanioslem, poczekalem 2 tygodnie i komputer odebralem
>"However, I had to leave the equipment at the customs office, because I reported entering with a computer, "you must leave it with us, now you have to write an application for license to import and own a computer", and I still have this application, I wrote it .... from Zarząd Ruchu Lotniczego i Lotnisk Komunikacyjnych (name of company managing Polish airports at the time, his employer) I received such support "requesting to grant permission, computer will be used for the calculations of airport procedures etc." and I took it, I waited 2 weeks and I received the computer
So as you see even Bajtek chief had to have a license to own mere C64.
