The real project:  I always liked UCSD Pascal.  I have the original 
Niklaus Wirth P4 Compiler project including the interpreter.  Now, in 
the UCSD system everything except instruction interpretation was done 
in Pascal.  The interpreter was a couple of k of 8080 assembly 
language, maybe more with the floating point stuff.  I don't intend to 
be quite so pedantic.

I was going to write the file system and loader in C and I thought the 
editor could as well be in the flash.  The command interpreter would 
only have a few commands: Edit, Compile, Execute.  Everything would 
run out of RAM.

I don't want Linux or any variants; I have that on gumstix (XScale) 
and a couple of PCs.  I want to recreate the simple environment of the 
UCSD system without the licensing issues.

The goal is to recreate the environment so I can use it to teach my 
grandson how to write programs in Pascal.  He can learn Linux & C 
later.

I had thought that the Olimex LPC2294 development board with 256k 
internal flash, 16k internal RAM, 1MB external RAM and 4 MB external 
flash would be more than adequate.  The original system ran in 64k 
bytes.

I would certainly consider the ARM9 if I could find inexpensive 
development boards but only if it is supported by the Eclipse->GNUArm 
tool chain.  There is no budget for development tools.
