Was or is Dungeons and Dragons popular in Finland?
It is pretty popular here still, and similar roleplaying games. There are a lot of nerds :) Some of my friends have been playing since the 80s.
The 64 was the first "computer" I ever used, but it was on friend's machines, not my own - but I do know the sound you are talking about! My first was a second-hand Amiga 500 in the early 90s.
