Right, I wasn't suggesting you do such a port, just that it's something
to know about if you have an ongoing in Forth for the MSP430.

I also notice that amForth now runs on the 430:

  http://amforth.sourceforge.net/

This is a very well documented system that runs on the Arduino and
claims "AmForth implements an almost compatible Forth 2012 indirect
threading 16bit Forth."  But, I've never used it and the 430 port is
newer and (for now) possibly less developed.

I just meant wires connecting the cpus together through gpio and bit
banging, since there's just one hardware uart per chip.  

Actually a REALLY crazy idea might be an all-to-all spread spectrum
broadcast network.  You'd connect an analog pin from each chip through a
resistor to a giant backplane (aluminum foil sheet maybe).  Then you'd
pulse messages to the backplane according to a spreading sequence
generated from the target address.  The target would listen to the
backplane with a software autocorrelator.  The bit rate would have to be
pretty low.

Nice, somehow I thought those boxes were smaller, but I haven't looked
at one lately.

The GA1K scheme sounds potentially workable.

You'd need 10 bits to address 1024 nodes individually, but the idea
wasn't to send a separate address with each bit.  It's just to send the
1024 bits as 128 8-bit bytes with a normal uart, rather than a special
software uart that collects all the bits synchronously.  That lets you
use the hardware uart on the chips.  Also in the case of normal graphics
where most of the leds are on or off, RLE (run-length encoding) can
compress the 1024 bits by quite a lot.

> if I calculated correctly 10 frames per second - moving graphics

If you want to display video then the transmission speed matters, 30 fps
x 1000 bits = 30k bits/sec, or with 3-bit greyscale (PWM dimming) 90k,
and maybe the uart can run at 115k, so there's a chance.

For the Pong game I was imagining something more like a cellular
simulation.  The 4(?) nodes displaying the "ball" would move the ball by
informing their neighbor in the appropriate direction that the ball was
moving to them.  Eventually the ball would hit a node with a paddle and
bounce.  The paddle nodes would also move up and down by local
communication.  This is more in the G1K spirit, I think.  You wouldn't
have to send anything to all 1024 nodes simultaneously, though there
would have to be some kind of "reset" message that you'd send to
initialize the board at the start of the game.  It's ok if that
propagates through the network at fairly low speed, like 100's of msec
to reach all the nodes, before the game starts.
