A vintage DIY 6802 microcomputer system built by the 'hp Micro Computer Club' in the 1980-ies.
This was a gift from a friend. I got i running long time ago and until now it was collecting dust in the attic...
Maybe at some time i will get to revive it and get it running again. As a first step i looked what is there and took some photos.
Next step will be dedusting and cleaning it up ;-)
