In Warsaw Pact countries were assigned specialized roles by USSR. Poland was supposed to make tanks, radars, radio, agricultural machines (including planes), etc. And we had pretty good industry in these domains. But in each case - for example tanks - there were always some parts you couldn't make in one country to prevent uprisings. So for example for tanks we took some crucial parts from Czechoslovakia.

USSR was able to do whatever it wanted of course.

So, to this day we make good military RF-related tech (see WB-Electronics and Radwar for example). But when we tried a space program in 60s ( https://en.wikipedia.org/wiki/Meteor_(rocket) ) - USSR made us stop pretty quickly.

Back to the subject - East Germany and USSR was supposed to do integrated circuits, so our industry wasn't very good in that regard. We made some, but nothing modern. Polish-made computers were mostly using foreign ICs with the exception of a Polish-made clone of 8080 used in a series of computers by Elwro.

Nowadays we have one pretty big IC factory in Poland ( https://en.wikipedia.org/wiki/Wilk_Elektronik ), and a few specialized IC factories for military and industrial automation.

On the other hand Poland is pretty big in software, especially gamedev.
