Nice 8) . If you want the contents of the EPROM chip with the uncovered window not to decay, it's best to cover the window with either a paper label or black insulation tape.

Yeah I noticed that. I'm guessing that whatever is/was on it wasn't that important to the previous owner

I had to Google to realise there is an actual difference. You learn something new every day!

A very nice boxed issue 4 beeb with all the leaflets and original guarantee (and an Acorn cassette player)! Not fully tested yet but boots up fine and all keys work.

I now have a boxed beeb for each of my kids once they are old enough. They *will* get into retro computers!

Glad it arrived intact.

I'll take this opportunity to raise a potential problem for AP5 kit units:

The 2 x 20 way connectors, for the User Ports, are new - old stock. I've noticed, when I've been building them, that the pins have become 'aged'. So I've been pre fluxing them and activating with my heat gun, before soldering. So I'm recommending something similar for kit builders. e.g. Check they're soldered correctly!

Thanks - Dave H :D

Actually, wouldn't an EPROM be OK in practice if it was inside a Beeb that was kept closed? I doubt much light would get in there!

Yes, if no, or very little light can get in, it does not matter. But it does depend on which case he has (different cases have different sized slots at the rear). And where it is kept. And this assumes the lid is fitted most of the time.
