Re: A83: C compiler for TI83! (PAT)
The 68k products are written in a combination of C and
assembly language. Most of the math and core utility routines
were done using assembly. There are some areas of the 8x calc's
that are faster than the 68k products, but thats the trade off
for ease of coding and implementation time of developing in C.

Just had to stop you here...would you like to see a Windows 98 written in ASM?
Nah, me neither :)...they're not getting sloppy
by using a HLL. But I admit, the Win95-98 series is slow, but for other
reasons.

Couldn't agree more...look at Ti-BASIC. Urgh.

Pat got any comment on this?...it'd be interesting to know what your input is.
Later,
James.
