Yeah, the good old Lawtronics eraser, there was one at work, a huge thing that could erase an entire board of EPROMs in one go, the photo reminded me of the colour. It had been modified with a pre-start so the lamps got to their peak UV before the board was placed inside, then it was around 10mins per board, the lamps didn't turn off between switch overs (another mod)Couldn't resist this. I've always wanted a Lawtronics eraser. Had a 'good' one in the '80s/'90s but don't know what happened to it when I left in '94.
Package was delivered fast! On testing the lamps worked but the timer didn't. Had some fun doing the fix which was just a 'sticky' synchronous motor. A good soak in WD40 and it works a treat. The lamps are driven from a standard Fluorescent circuit. I'm going to replace the starters with the solid-state ones to minimise the damaging effect of the 'standard' starters.
So, that leaves me with one of the cheap Chinese ones. I've not had any problems with this other than capacity. Free with P&P for anyone who would like it - You'll need a mains plug![:wink:]( "Wink")

I think it got recycled, I didn't want it, only now do I think I have enough EPROMs to fill it - and then it would be all of them, all at once
