There was a “Pop!” and a bad smell. Looks like one of the chips failed. It’s all surface mount so there’s no chance to fix it, especially as the chip that failed is a large QFP with about a hundred legs.
Sorry Greg! I only got to use it once or twice.
Bugger. I’ll dig a few more out of the shed on the weekend for you – I definitely have a few spare. Joys of antique electronics!
