I got the source for CP/M 3.0, any idea what we can do with it?

There's Z80, 8080, x86, and 68k, too. The link is the full source for 80 I think. Linux rejects "make", because it has no 'cc' command.  :-\

It's source for a really primitive OS. I was thinking of an z80-8x-family port.

Could be cool. I'd like to see what people manage to do with this.

Indeed. However, someone on Cemetech has had a similar idea, and, as Ben Ryves has pointed out, there are issues (see http://cemetech.net/forum/viewtopic.php?t=6323) However, with some adjustments, and breaking compatibility for all existing programs, this could work quite well. :) (no sarcasm intended)

I was thinking of completely redoing a lot of it.

Hmm... Looks interesting. I wonder what screen resolutions are supported for the Z80 version, and how much space it would take up. I'm also curious as to what if any programs are included in the os (word processor, basic calculator etc.)?

For resolution, it expects and 80-char wide terminal. Someone would have to hook scrolling the screen into it somehow.
I'm not sure anything is included besides the terminal.

We could also use the small GraphScreen font.

Bummer. :/
Small font would help some, but that would still only be 24 characters. :/

You'll have to recode almost everything involving the screen, as it has a very low resolution, is only black and white (or you'll have to let it manege gray scale by flickering the pixels) and it has a very slow driver.

further, you'll have to code stuff to use the link port, so you can still download programs for it.

I think this OS would also be incompatible with all programs and applications for the z80 calcs.

seana seemed to show great interest in porting CP/M to TI calculators: http://www.cemetech.net/forum/viewtopic.php?t=6323&postdays=0&postorder=asc&start=0

I don't think it's a practical project, the whole OS would have to be mangled for it to really work correctly (and efficiently!) on a TI calculator.  Plus, it would get rid of all compatibility with normal games/utilities/programs.
