Lately I’ve been revisiting some work I did using Set Theory 10 years ago.

Having not come back to Programmable Calculators until 2016, a long gap from programming the HP-97 back in 1981.

I haven’t got the length and breadth of experience that you guys/gals have with Programmable Calculators - some of it amazing and highly technical.

My best working calculators I have are the HP-41CX and HP-15C plus a DM41 and DM16.

I like that you’ve been very supportive of some probably simple questions to you but not to this 70 year old semi-retired Mathemation!

Back to Set Theory - I’ve done a fair bit of looking for anything Set Theory related on The Museum USB Stick and online.

Can anyone point me towards any articles or software that I could use on both my vintage HP Calculators and/or my later models, namely HP Prime (1st edition) or my HP-50G that relates to Set Theory please?

Finally do nearly all HP-42S programs run on the HP-41CX?

Thanks

Dennis
