Would it be the Texas Instruments calculators, Joseph? I've seen your
posts in bit.listserv.calc-ti. Certainly a compiled high-level language,
C or Pascal, say, would be a mighty improvement on TI-Basic for
programming the calcs.

I posted here (c.o.cpm) a while ago (April) asking for
information from the CP/M gurus on this subject.

Anybody else have an opinion?

I've cross-posted back to bit.listserv.calc-ti, as it seems to me that
some cross-fertilisation on these ideas might pay off.

The Nintendo Gameboy also uses a modified (simplified)
Z80.

*nod*

I had begun work on a unix distrobution myself (a port of minix, with
Tanenbaum's blessing), but its quite cumbersome coding it. When I found
uzi, I thought it would be a slight bit easer to port, which is why I am
looking into it now. I have decided I am going to attempt to compile it
with a distrobution of a small c compiler, having edited the c source to
control the bios beforehand. If you have any ideas, email me.

Yeah, but it is far different from the one used in TI's.

I use MSX and MSX-C produces the assembly code when it compiles the source.
Therefore I can make HEX file from the assembler source.
If there are C - library especially for TI-8?, C compiling should be
easier.
Otherwise we change ordinary system calls to special ones for TI-8?.
