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 on a sunny afternoon.
