Geoff,

I've never bothered testing old components. In the waste they go!

Unlike you I don't have a "lab". I used to do any personal stuff at work where I had access to some pretty nice equipment. Not now. I have a old soldering iron, solder sucker, and solder wick. Wires are pretty much it these days Sad

The brain is willing but the body is not.

Some months ago a 13 year old consumer electronics item failed for the 3rd time. I didn't even open it up. Out it went! I'd already purchased a replacement so it was all good. However the manufacturer had changed the product but kept same model number so I had to "tweak" some stuff to get back where I used to be.

So it is not just old calculator stuff that fails.
