Happy Birthday to Me ...

[Bill Duncan]

I still have my original 29C.. While there are certainly more capable systems now and the HP-15C is a great shirt pocket calculator, it holds a lot of nostalgia for me as well. Olivier De Smet also has an HP-29C emulator which is very good btw.. I also have his go41cx and go48gx apps. Excellent.

While I have about 3 battery packs for the HP-29C which aren't working at the moment and need some repair, I have a friend that is going to 3d print me a battery pack.

Keep in mind that you don't want to use the charger directly on the HP-29C without a good battery pack or it'll smoke it! In my youth, I had the foresight to buy an external charging unit for the battery packs..

..and happy Birthday btw!
Cheers.
