First of all, I wish to humbly thank you for the private messages you sent to me through eBay and for posting here. I think it’s an amazing testament to the wonderful person you are for having chimed in after all these years. And yes, your card did last quite a long time.

I use my calculators at the office and I’m at home for the weekend now, but on Monday I will use my heat gun to re-flow the solder, as that would be a more accurate way of doing it than touching each pin with an iron, which possibly could cause accidental bridging. I will then report back if that helps.

If it doesn’t help, that means one of the chips must’ve died for some reason.
