Ok. So the things that I notice from those pics are that there seems to be some
sort of board mounted on the back, which I've never seen on another
mathine. The
tube is mounted in a horizontal fashion instead of vertically, the
programmer's console
is a different style than any of the ones Bob or I have in that it has a
selector knob.
The photo here

also seems to have that knob. The next time that you get the chance, could
you take
a couple of closeup pics of the console for me. I would like to see what
all is on it that
ours do not have. Lastly, it looks like there is a wire wrap board in the
long vector
section of the machine (300-304).
The board in the center row, right-hand side is
the TTY interface board.
The long vector hardware is most probably that odd board added in the
core memory section, top right in the picture.
I'll try to get more and better pictures (Tom requested them too) so we
can get a better look. Trouble is the machines are tucked away in a tight
area. It'll be a few days before I can get out to the warehouse and pull
them out.
In the meantime, here's a link to pictures I took when I first brought
home my PDS-1D:

The idea is to get them working at some point. I'm
hoping Greg Thomson
(Maze author referenced previously) will take an interest in helping me
out. It'd be really cool to have a real game of Maze in my garage with
the original author ;)
Indeed!
