HP15c CE questions

[Johnh]

I'm enjoying it too. I think with its simple, compact and accessible layout, and very clear though limited display its best role these days is for ad-hoc calcs, backed up with the extras such as Solve, Integrate, Matrices and Complex numbers. I find programming it is best used for a few very familiar routines that help with what I frequently do.

The main remaining limitation for me is the lack of Alphanumerics, to help remember the inputs and outputs of a program. The power of the maths and programming is plenty to set up some quite sophisticated and extensive routines, if you can remember how they work!

Now that Save to PC is available, I'm thinking to make a card to keep behind the calculator, with a summary of input and output order or memory references for my main programs.

The use of an Hp15c is also greatly enhanced by the availability of several very good emulators, to use on a mobile phone.
