Exactly how difficult would it be to write a kernel say for a TI-83+ that would be useable in Windows in C++? Also, would there be a better language to write it in? Thanks ::tim

"that would be useable in Windows" If you write a kernel for the TI-83+ (which won't work unless you have some way of overriting everything on the 83+ and I don't just mean the programs on there) it will not work on Windows. A kernel is the heart of an operating system which controls all of the hardware in your system. Also, the 83+ only has an assembler for it, therefore C++ or even C will not work.

1. I believe he means shell. 2. The TI-83 uses a Z80 processor; it would not be possible to make it compatable with Windows (which *typically* uses an x86 processor, completely different interrupts, and different core functions). 3. I do happen to remember a group of people writing a C compiler for the Z80 calculators that runs on Windows...I used it once, it was a POS (at least, it didn't work for my TI-85). 4. If you don't already know how to write a shell (nevertheless what language to use...), then it's WAY beyond your scope. AKhalifman@hotmail.com
