16 bit is fine, the MSP430 is a very nice processor to program in 
assembler. I was just thinking out loud, it might not hurt to have some 
extra words that are Forth generic.

The PDP11 is very nice for it's day but compared to modern CPUs it is 
register starved, I'm mostly interested in Forth CPUs and there are a 
few available, some are very simple such as the J1 CPU but with minor 
changes it can be improved but then I would need software that works 
with it hence the reason why this software is needed.

I'll send you an email tomorrow or a modification to the assembler and 
get feedback on it.

Big thunderstorm rolling through so I will need to turn the PC of for a 
while.
