I use hp48 app on the iPhone.
Obviously it does not have the tactile feedback of the original. But it’s a far cry from using on a desktop with a mouse.
Using a REPL as a replacement does not mimic the experience, I don’t think. Not for me at least.
Mind, I’m talking a generic REPL. Like a CL REPL or similar, obviously not some custom calculator REPL.
First off, you’re missing the stack, which is significant. CL can almost mimic this with , *, and *. But while it provides a free, handy value store, it’s not the same. You’d end up with contrivances like:
(* * **)
Then there’s the value of the special keys (i.e. SIN et al, gives a new feeling to the term “function key”).So, for me, a calculator and its hand held form factor, especially something like the high end HPs, go hand in hand.
No doubt someone could (and likely has) code up a dedicated calculating experience, but a generic REPL I find to be unsuccessful in that role.
