Tofu - the HP calculator "simulator" for PalmOS

For a while i've been thinking of writing an HP 48 emulator for PalmOS. The lack of CPU power doesn't put me off, i want it for the maths, not the games. What did worry me is the screen layout. So i wrote an application to test it. It has all 49 buttons, 6 annunciators and the 131x64 pixel screen. They layout is a little cramped, but it works. To really get a feel for it, i wrote an integer RPN calculator to go with it and emulated the four menu buttons (but not the softkeys, apart from the "About" button in the VAR menu). There's also the display test available from the PalmOS menu.

The Tofu48 application is available as a PRC file. It requires at least PalmOS 3.0 and has limited support for the 240x320 mode of the Handera 330. (It runs in high-res mode, but the graphics are still at 160x160 res, just centred. I did this as it looked really horrible when scaled.) It is and also as a ZIP file containing KML scripts and bitmaps for emulating the HP 38 and 48 in Emu48. The HP 38 simulation only exists for Emu48, i have yet to write Tofu38 for PalmOS.
