Yes but can I run it without a monitor? I have no desire to run the p21
stand alone, yet. The forth I wrote/ported for the transputer, hc11 and hc16
all use a server I wrote for the p.c., the protocol lets the micro talk to
the p.c.s vdu,keyboard and disk system. If I get involved with the p21 I
will be porting my forth to it. Any stand alone system I build will probably
use lcds. The question is should I just start from scratch and not bother
with the software that come with the kit at all. The tranputer used link
adaptors and the c11 and c16 both use rs232 at 38.4 and 115 kbd with
hardware handshaking. I was thinking of looking into using a bidirectional
printer port for linking to the mup21. I have the p21 forth port earmarked
as a holiday project, I'm spending 2 weeks on a coral island with no
buildings on it yet alone power. I usually take a notebook p.c. but I
definitely won't be taking a monitor.
