[Coco] Question re: NitrOS9

[Dave Philipsen]

I am currently working on an FPGA project running a synthesized 6809 at 
25MHz with a VGA display and PS/2 keyboard.  It is loosely based on 
Grant Searle's Multicomp implementation but I've got a MMU that emulates 
the CoCo 3 with 512kB of memory and a hardware timer that will provide 
interrupts at a range of different frequencies including 10 Hz, 100 Hz, 
30 Hz, etc.  It also has a Dallas Semi real-time-clock, a couple of 
serial ports, and I'm working on an SD card interface.

What I'd like to know are the minimum requirements to run NitrOS9 as my 
next step will be to start porting it over.  This could be a handy 
little system for anyone who wants to run NitrOS9 on a small computer 
the size of a deck of playing cards or smaller.  Initially, it will just 
have a text-based display with an IBM CGA character set and the 
display/keyboard will just run as if it were a serial terminal like a 
VT-100.
