@slobu Your retro fetish affections are controlled by external appearances?
Any bare board that is left open without shielding is a danger. You could shock yourself or fry the board with static/coffee/dropped screwdriver/pet hamster.
That said, I do care about appearances. I make sure to stuff at least two boing boing balls down my trousers whilst emulating my computer of choice. The neighbors could be watching, you know.
P.S. I've never beaten Barbarian or Blood Money so I don't consider it retro - it's very current for me!
