I see. I was thinking fundamentally the hp 35s and the simulator have a "rom.bin" inside, kinda like all the emulators we've used over the years, including yours.
But instead, if I'm correct, HP has several well preserved .c or .asm files, with a bunch of routines that haven't been looked at in a while, that were a long time ago written and compiled for the hp 41 Math Pac, then compiled for the hp 32s/ii, then the hp 33, and now finally the hp 35s, and the simulator.
I don't know enough about what's going on under the hood. I am just trying to figure out how easy/difficult it is to fix current calculator bugs, regardless of economic decisions. In essence, could/does a bug free version of the hp 35s exist, even if HP is not interested in updating manufactured units, and would work in the simulator? Or is fixing the legacy code itself too monumental a task?
