His lateset version is risc machine, a machine I don't like because
they have too
low a instruction density. Now does it really matter if you use hex or
octal or what
ever? On Mon, 7 Mar 2005, Ron Hudson wrote:
Cool is it 12 bit, best expressed as 3 hex digits?
I am beginning to write a simulator for a
"microcomputer", it will
feature a
curses (terminal) front panel. it will be a 12 bit machine. You
will be able to
issue commands to the simulator without stopping the program (for
mounting
virtual paper tapes, printing to files etc)
Cool! If you haven't, check out Donald Knuth's fictional MIX
computer. It's a mishmash of a bunch of "contemporary" (1970s)
architectures. The cool thing about is there is SOFTWARE written
for it, even though it never physically existed.
There was no physical representation, if you were to make one,
it would add to the coolness of it. Ben alias woodelf
