Music produced on two Swedish computers from 1967.

Saab was the main computer company in Sweden from the 1950s up until the 1980s and around 1967 Göran Sundqvist produced some music on two computers made by Saab called D21 and D22. You can listen to the mp3s of this fantastical music here: http://www.datasaab.se/D21_D22_musik/musik.htm
