So I got a second HP15c calculator. Where can a bloke get some help with addictions, asking for a friend.

Karsten Konrad 📯 For me, the HP Prime is the only one I need.

xialulee It's a very powerful machine! I have one too, but I also have a soft spot for the minimalist perfection that is shown by the HP15C and DM42 - as soon as a calculator goes symbolic, there is a lot more mental load to deal with. Still, love that Prime as well.

Karsten Konrad 📯 I've never used an HP15C. Based on your description, it must be a great calculator.

Karsten Konrad 📯 Yeah, 1982—three years older than me.

xialulee Then this is your birthday calculator: en.wikipedia.org/wiki/HP-34C
