The monitor hooks up to the cpu with an odd "dual
din cable". Two din
connectors on each end, one has about 9 pins the other has about 5 pins. The
monitor obviously gets both power and data on this dual cable.
Yeah, I'd forgotten about that. And in a system that gets moved or whatever
where those get plugged/unplugged a lot that's a source of trouble,
particularly when one of the connections in the power plug gets a little
The CPU appears to be something called a "Wang
Professional Computer" from
what I can glean from the docs. The model tag on the back is extremely
faded black print on silver so it's just a shadow.
Sounds like old thermal printing to me.
It seems to say the model is something vaguely like
PM-XC1. There is an IBM
mono "module" which has a part number something like PM101
The original machines were not hardware compatible with the "IBM PC" so they
added that board to give that compatibility, I forget exactly what it does,
but it's some sort of remapping of hardware.
and a "winchester controller module" which
has a part number like PM029.
The host adapter for the HD.
From just a 30 second skim of some of the manuals it
appears to be running
a very customized version of DOS. The proprietary changes to the OS appear
to be more than just cosmetic.
Two things come to mind offhand: One is that the "switch character" is going
to be "-" instead of "/", and the other is that there's going to
provision in at least some stuff for that odd keyboard that Wang used --
which had a return key and a separate "execute" key, now that I'm thinking
about it. I'd forgotten about that...
The price was reasonable so I picked it up. The seller
said it came from a
WANG dealer - since there's a lot of what appear to be diagnostics & test
diskettes, I would imagine that's the case. I will play with it for a bit,
but may well be interested in trading it off. I did note that the seller
had more of the proprietary CRT's and dual din cables if those are of
That system being newer than the stuff I worked with, there may be someone
who's interested. When I had that last "Wang PC" around I couldn't even
it away, even to the one person I knew of that still had one (they had it in
a closet, they told me).
