- Ok yeah, I think this would be good, I have been trying to borrow a 48
- for a while now but strangely enough the people who own them keep
- using them. It was suggested that constants/formulas could be stored
- in a user editable 123 worksheet. I think that these should be
- editable from within the calc. application itself. However I suppose
- that it might be desirable to edit a master list for labs/courses on a
- desktop and distribute that to the individual HPs.

- True, but it looks very easy to allow at least stack dumps/receives
- over the IR port. And hey, someone might need it. It's definately
- something for final gloss though, I won't worry about it for a while.

- That's true, and one thing I have noticed is that I never reach for
- Mathmatica, Maple Theorist or MathCAD unless I need to do something
- *very* complex. I doubt I could even approach Derive's power, but I
- hope to fill in a few gaps.

- Ok this stuff is all certainly possible. I'm not sure what you mean by standard
- operations. Is this part of the RPL programmability?
-
- One interface note. I think a large part of HP's built in calculator's
- problems lie in its interface. The menuing system is a real pain and
- slows down the user's ability to operate the calculator severely. I
- was thinking that mapping the most common functions to keys would be a
- fairly efficient interface that would prevent the proliferation of 5
- item menus which seem to have no bearing on each other. Menu input
- would still be possible, to avoid confusion but (assuming this ends up
- as shareware rather than freeware) registered users would get a ...
- Key Overlay! HP listed their recommended source for HP95 overlays
- which shouldn't be too expensive. Also a postscript version would be
- bundled with the thing for folks of the roll your own mentality.
-
- Too impractical? Actually I think it might do wonders for
- registrations although I'm not looking to make money off this by any
- means.
