PSIONs: MC600 and Org2
======================

The MC 600 is a nice laptop with a passive LCD and a great keyboard. IT
also runs  the MS DOS 3.3.  It means that  it can run PSION's  ORG2 IDE
(that is, the  integrated development environment for  the Organiser II
with a debugger and the emulator).

I have  been using it  in this role  (albeit infrequently) and  I wrote
about it before some time.

But I always needed to transfer the files to a desktop machine and then
transfer them to the Organiser II. This is of course stupid because the
communication software  is of course  DOS-based. Thus it should  run on
the MC600, too.

Recently  I have  tried  to use  it. The  CL.EXE  works without  issues
but  the  problem is  the  cable.  The MC600's  serial  port  is a  bit
non-standard: it is a round one  but not the famous Macintosh-like one.
The Series 3a cable  can be used (it consists of two  parts and if they
are separated then MC-compatible connector  emerges). But I cannot find
a correct adapter for connection of  25-pin Organiser II cable to 9-pin
end of that MC's cable.

But recently I have found at eBay an "MC serial printer cable" with the
25-pin end. It  ideally connects to the Organiser II  cable. But that's
all.  That setup  does  not work  -  the Organiser  II  cannot see  the
"desktop" machine on  the other end of the cable...  As the cable seems
to be intact the problem is probably in the pinout. So I have to search
for another adapter...


P.S. The  parallel cable for  the Atari Portfolio work  without issues.
But the MC's parallel port is the standard one.
