OpenRPN - A Dissenting View Message #1 Posted by Steve S on 15 Apr 2004, 7:50 p.m.
...Since I've written in the Forum recently about new calculator design activities, I won't bore any of you by rehashing old material. But I would like to articulate a couple of thoughts, just for the record. In terms of presentation, a tip of the hat to Nelson for suggesting a clever writing approach!

1. Reading the existing discussions, it still seems to me that most people here are simply looking to resurrect a slightly improved version of an existing HP design, like an HP-41++ or an HP-16++. I think it would be a terrible waste of time and talent to settle for such a thing! It's the 21st Century! Can't we collectively think of something a bit more clever than how rounded keys should be or building it out of aluminum?
2. Rhetorical Questions: If HP thought this way, would they have ever leapt from HP9800 to HP-35? Or produced the HP-75 / 71? Or even the HP-48? Didn't all of us look to HP to make quantum leaps in product design and capability over the years? Why should we settle for less?

3. I like crisp, double-shot keys as much as the next guy.
4. Keyboard label clutter beyond a certain point is undesirable.
5. More display area is ALWAYS, ALWAYS better.
5a. Color displays are better than monochrome.
6. A folding design (a la LX100) is an acceptable form factor for a dedicated calculator.
7. Well-implemented soft keys are a good way to preserve access to functions while avoiding clutter.
8. An original calculator design is more appropriate as a project than a warmed-over redesign of an "old classic."

...In my mind, it's long past time to think beyond calculators as we know them today. My ideal design would be a slate, 8.5 x 11 or somewhat smaller, that you would WRITE numbers, calculations and equations on. Hand writing recognition would convert these to characters and solve the problems. Graphs would be interactive and would pan and zoom just as CAD systems do (and as easily!). As each "page" filled up, a new one would scroll up, and all previous pages would be saved, JUST AS YOU DO WITH PAPER.
Well, OK, that's crazy talk.
How about this: An LX-100-sized case with a large color LCD screen, flanked by two or four (2 left and 2 right) columns of soft keys. The other half of the case would have a conventional arrangement of one-per-function keys with, say, one or at most two shift keys. And YES, put the damn ENTER key right where it belongs!
Calculations acummulate and scroll on the screen, saving to one of those nifty small disc drives. As various functions and modes are invoked, labels along BOTH right and left edges of the screen change to "label" the adjacent soft keys and maintain the one-per-function approach. USB connectivity assumed, and windows-like file manipulation to load and swap libraries of functions and data.
Now, THAT would be a calculator worthy of our combined talents..!

...Hey, wait a minute! This damn key is stuck down!
Oh, no.....
