8-bit acorn hardware • Re: Thoughts on a suitable EPROM Eraser

Huh, not sure it's even worth erasing them; 4k and 8k... No 27128 chips?
They could be used for Tricky's Test ROM, the 2732 is a 24 pin IC so it's useless in the Beeb without a carrier to convert the signals to 28 pin layout.

I've got a cheap eraser from China, "Leap" branded (perhaps what happens when you touch the case Image may be NSFW.
Clik here to view.

) I bought it in Shenzhen years ago, there's very little to it, an inverter, a micro switch and a mercury lamp in a quartz tube. Bear in mind that the tube needs a few minutes to reach full UV power as its spectral output starts off mainly in the visible and then the UV ratio increases with the temperature of the mercury arc.
