That's the one...

All the normal Forth words including C! and C@ etc are there...
It's a fairly full featured Forth, it just runs out of the eprom
which replaces the ZX81 one, rather than a program that loads on top
of the ZX81 system.   Blocks on cassette are a difficult thing to cope
with though!
It would be nice to make a copy eprom though, just in case.  Writing it
out to cassette would be possible, but a bit tedious, an eprom burner is
the answer I think...

At the time it was very impressive to see multiple applications running
simlutaneously in (tiled) windows on a ZX81, come the think of it it's
still quite a feat.

(I have Forth on just about every machine here, from Mac to PDP-11...)
