Tech Tangents S02 E77 Casio CQ-1 Diagnosis and Repair

I decided it was time to solve the problem with the Casio CQ-1 I was sent in. I didn't have a lot of hope, but it went better than I expected! I'm really happy to have got this working! It's such a cool calculator and I felt bad letting it sit for so long. Well it's finally up and running again.
