Got an untested Timex Sinclair 1000 for giggles, turns out it only need 30 minutes of work to fix. Now its a tested and working Timex Sinclair 1000. I know.. I know... it's still a piece of junk lol.
I had one of those, it was a good cheap learning tool for BASIC programming. I also had a few games for it, like the official Frogger, which sucked out loud.
