I can try to. 11/750 is a nice machine :-)

I have one that I have used for testing NetBSD for ~8 years. Unfortunately
one of the power supplies are broken right now, but I plan to fix it.

Yes and no. The driver from 4.4BSD is ported to NetBSD, but the licence
issues are not yet solved, so the code cannot be in the tree.

I have vague memory that the TU80 has the same interface as the TS11,
but my memory may be weak. Anyway, if this is the case then it is 
supported by the ts driver.

"man 7 hier" will give you an overview of the tree structure. Or:

http://netbsd.gw.com/cgi-bin/man-cgi?hier+7+NetBSD-current

if you do not have any man-pages available.
