Landscape RPN calculator with alphanumeric display

[walter b]

You made me looking into my old files again. Let's see, for example:

1. This was presented on the forum in 2008 (including a LCD available at that time).
2. This in 2008 as well, showing what a better display could do.
3. This was shown in 2009, just redefining a 15C.
   

Then the WP 34S took over. Please note all my above designs are just mockups - what we call vapourware here traditionally for reasons found in the depths of the old forum (search for OpenRPN). There were layouts of portrait shaped calculators, too. And of course also other forum members designed their dreams (I remember Jeff O. and apologize for the others I forgot).

At the bottom line, layouting keyboards is fun (and graphic output makes your readers / viewers sharing it) though the real fun and satisfaction comes with a real platform IMHO. AFAICS, such a platform is missing for a landscape RPN calculator with alphanumeric display.
