@tubetime I was having to erase EPROMS with a UV light as late as 2007.

@tubetime Funny timing. I have just gotten back to this and just got a T48. Unfortunate the sun couldn’t erase my HN462532G today (only a single bit flipped). I might have to buy a UV lamp.

@root42 that's from decayed ESD foam. but yeah I think they cheaped out on the plating.

@tubetime IMP-48 and SMP/80 seems interesting 70‘s home computer monitor stuff.

@tubetime you realise the world will end because each and every one of those hasn’t got something covering the windows.
