Next big step is to get the rack into the basement, not an easy feat.

I have uploaded more photos of my TU10M (it's a master with the TM
backplane installed). I also updated the design of the file listing pages
on my site to make it easier for people to find things. One of the images
shows it has the RSX-11M tape loaded.
I have been cleaning the cables, having fun

Well, there was also that large intermediate generation which still had their

We've repaired them with cut outs from latex gloves. The problem is the

I am going to see if I can find the card inventory and installtion guide
info for the TM11 so that I can confirm whether I indeed have one
installed in the TU10'S cabinet. So far I have found little.

Thanks. There are 2 backplanes at 90 degrees of each other installed in the
cabinet. 2 separate power supplies.I still need to inventory the cards
and look up what they are configured to do. I have cables. Just getting
started.

I am just getting started. Here are a few pictures

My immediate goal is to clean, disassemble and then get it into the
basement before the stink bug season starts.

Quick documentation check ... I think I made a mistake :-(
TM11 and TMB11 are very different!
I am no longer sure that you can connect a TU10 to a TMB11.
Should probably indeed be a TM11.
I should check docs first, next time ...
Apologies,

Ok. I checked my tu10, it has the backplane, it is a master. I see where
it connects using the backplane cable to the pdp11. I never worked with a
TU10 before
That is one of a handful of DEC items I'm still looking for, so if anyone
has an extra or running out of room, please contact me off list.
I would plan on the capstan being shot also. Anyone have any extras?
