Was looking for this one, was sold in large numbers in Germany, what the Final Cartridge and Power cartridge was in Holland, was the Nordic Power over there. Was a quick buy for 30 euro’s from Peter. He sold his Commodore collection a few years back, and came across both cartridges, still in storage. Will probably sell the Expert Cartridge again on Marktplaats and create some new disks for it, based on the available D64 images.
Funny thing was that after I asked what figure he was thinking of, he told met that the cartridge back then costed 150 guilders….I told him that the Commodore back then was 800….and you can get one for 30 euro’s nowadays 🙂
