I worked for a now long defunct company with half a dozen of each, no idea which revision. My job was to crack and re-enable copy protection to create master tapes for bulk duplication.

I was told (as a teenager) that we had agreements with the copyright holders, but I never saw them. We also had an Orange..an Apple ][ clone, a Sinclair QL and a few Commodore and MSX machines.

My own computer was a VIC-20.
