Thanks for that, I've saved the info and will have
a play when I get time.
I will see if I can find the Sharp CE158 user manual (RS232/Centronics box
for the PC1500). If I can, I'll provide more details.
When that'll be I don't know, I've just
received some old FigForth listings*
to scan in or, probably, re-type. (PDP11 and Z80 if anyone wants to know)
Somewhere I have a printed version of the Z80 Fig lisitng -- it's clearly
a hack from the 8080 version. A friend of mine once ported it to the
Tatung Einstein -- I should still have that somewhere too...
Hunting around on this machine I've found what seems to be the Macro-11
source for PDP11 Fig-forth (RT11/RSX-11/standalone) and the 143K file of
blocks contianing things like the Forth assembler, etc. I believe them to
be public-domain and if anyone wants them (and can make them available
for download, etc) they're welcome to them.
* Courtesy of the FigUK library who have a lot of old stuff.
You would get the 2 versions that I already have :-). I'd like to see the
6809 fig forth (I assume it existed, and used the 2 hardware stack
pointers, etc).
