Some assorted HP67/97 questions

Fine – thank you very much. There is just only thing that could be improved: after "reading a card" (loading a program) the mode settings do not show up in the emulator, e.g. the display format does not change. This only happens after an operation, i.e. any key press on the emulator. Maybe this can be improved.

So we now can think about the icing on the cake. ;-) I wonder if it may be possible to add some kind of labelling for the A–E keys, similar to a program card that is placed in the respective slot above the keys...

Looking at the list in the PDF I think the mnemonics deserve some streamlining:

• Could the list please be sorted in any way?
• The "/x" for the "mean" command should be replaced by "xbar" or something other more intuitive.
• What does "CL" do? This was a bug in earlier versions (written by Save, but not recognized by Load). I think this this supposed to mean CLREG, isn't it?
• The use of the colon as a division symbol is not very intuitive. If it has to be an ASCII character I would prefer the usual slash "/", both for a simple division and for storage arithmetics.
• Why do DSP (i), GTO (i), GSB (i), DSZ (i) and ISZ (i) require a space wheras STO(i) and RCL(i) don't? I think the spaces should be removed.
• The list also includes a "LBL (i)". What is this supposed to do ?-)
• The spaces in the register arithmetic commands are somewhat ...disturbing. Why does it have to be "STO + 3" instead of "ST0+3"?
• Are F1? and F? 1 equivalent?
  

Both the manual and the emulator itself deserve a better HP67 image. The one I am using looks very nice and the mouse/graphics alignment is close to perfect. But since nobody seems to know the exact original source of the pictures linked by striegel...

Maybe someone can place his HP67 on a scanner and post the result here. If this is a useable base to start with I could do some image editing to get a decent HP67.BMP for the emulator.
