Oslo Børs is a stock trading game for the Commodore 64 that was widely distributed around the country hand-to-hand on copied cassettes during the 80’s. It turns out, most Commodore 64 users here in Norway seems to have found memories about playing this game, including myself. I’ve manage to track down the original author of the game after all these years and get some background story.

The game was initially written in BASIC by Thor Vollset on his ZX Spectrum back in 1982 as a hobby project when he was a student at NTNU (Norwegian University of Science and Technology) in the city of Trondheim in Norway. He remember using a lot of time for fine tuning. Then he got in contact with a local computer shop named “Folkedata” (people computers) and an employee there (Tor E. Johansen) programmed the Commodore 64 version of the game. The game got a printed cover and was put it in the shelves around 1983. Thor Vollset told me a bit later he first thought I was kidding when I told him the game was popular back then, before he was contacted by others that wanted to interview him about the game. He was never into Commodore 64 himself and moved on doing other things.

I’ve adapted the game for the PET/CBM computers and translated it into English language. The game will display correctly on both 40 and 80 column machines.

Bernt Ø. Thorvaldsen has made an improved version for the Commodore 64. You can now play against computer opponents and its possible to complete the game. Link to his homepage where this version can be downloaded:
