I still use my Casio FX-501P programmable calculator in the 'day job'. It's been fantastic! I bought it in October 1980 during my first term at university, £54.95 from WH Smiths, Cornmarket St, Oxford. I use the programmable facility maybe 10 times a year still. And although I'm a fan of Excel spreadsheets, when creating a new one I check the results of the spreadsheet manually, with the calculator, as a sanity check.
I did take the calculator apart once, for a good clean and regrease with contact-treatment, when it was getting 'iffy. That was 19 years ago. It has never missed a beat since.
I do have the FA-1 adaptor to store programs and data, and to play tunes - but this hasn't even used for I guess 25 years.
My only regret is that I didn't buy the FX-502P (with double the program storage). But Smiths didn't stock it, and I didn't know of its existence at the time!
