Thanks... I'm sure it will...

The backplane does appear to be the correct one...

It is... when I was in college (the first time around), I used to
write programs for it under RT-11... I wrote a program for an ME
grad student which displayed a four-bar linkage problem, allowing
the student to examine the results of various lengths of the legs
by actually moving them in real-time with the light pen...
Another program I did graphed trajectories of objects given initial
angle and velocity... it properly did clipping at the top of the
screen if the graph went that far, and did automatic scaling...
Finally, I developed a program which allowed design of logic
circuits using the light pen to first drag parts from a library
along the edge of the screen out to the breadboard field, then
wired them, then could supply a clock and test what the circuit
did...

It looks like it has the right cables, but I'll have to check when I
get home... Thanks for the info...

Turns out I have one in the box of parts... (see my list at the bottom
of this post).

Found it too in the same box...

I did find some familiar connectors for such things... I'll have to
check them out when I get home and see if they are what I need...

Not for someone who has seen the stuff before... I'm not a guru with
it, but I recognize what you're talking about...

I still have a box of printsets to go through as well... it may just
have that in there... we may both luck out...

More to checkout when I get home...

Haven't found the RL11 controller yet... I do have the bus grant
jumpers, and a terminator in the main backplane. The VT11
backplane wasn't even connected... but then again, it doesn't
have a power harness...

I don't think I saw the over-the-top connector in the machine, but I
think I saw one in the random parts box...

Yep, it has that strip...
