In the end I gave up trying to use a decimal arithmetic library and GTK2 and eventually opted for the much more ambitions goal of simulating the actual hardware as it was just too hard to get a modern decimal math library to compile on VMS or Tru64 UNIX (a retro project needs to be properly retro so being able to run the simulator on these platforms was one of my goals).

Fortunately there is a LOT more information available now than when I started and thanks to that and some encouragement I've actually done it. There are a couple issues I need to sort but basically it works!

Hopefully I will be able to add the HP34 to my collection as well, however a bit of a major keyboard/button redesign is needed to accommodate all those labels. I might even be able to add one of the Voyagers like the HP10C, if the processor is not too different - more research needed!

Thanks again to everyone that helped me get this far - I'm still pinching myself.

Bravo!

Hope you can get the HP34c working. It was my first HP calculator.

I need to tidy up a few loose ends and may try adding a couple of useful new features (like allowing the size of the window to be changed) first.

The most obvious difficulty with the HP34C is finding enough space for the additional function labels, without changing the existing code too much, so it may take a while sort out but it is on my to do list!
