Needed: RM80 (for KS10 restoration project)

I've finally managed to partially satisfy
my nostalgic obsession to resurrect a PDP-10.

I just recently located a KS10, and, after a 480
mile mile trip in the back of my poor little
pickup truck, it is now safely sitting in front
of my garage (still in the truck... It will
be _in_ the garage as soon as I can con a couple
of my friends into giving me a hand. This is not
a light load :-)

The next thing I'm going to need is a Massbus
drive (preferably, an RM80) If anyone has one of
these that they would be willing to part with,
please drop me an email note. I'm located in
Virginia, but I'm willing to drive a reasonable
distance to pick one of these critters up (the
closer the better, of course :-) Shipping would
be impractical.

The other possibility is to build an adapter
that I could stick in a PC which would emulate
a Massbus device, but to do this, I'd need pretty
complete specs on the Massbus (i.e. pinouts,
timing, etc.) Does anyone happen to have this
info? I've done a dejanews search, but nothing
really useful turned up.

If I can locate a partially complete RM80 (i.e.
one with the Massbus to modified-SMD adapter
still present and intact in the drive pedistal,
then I might try to build an adapter to emulate
the modified-SMD interface supported by the
massbus adapter cardset. I suspect this might
be a simpler emulation, but it would still
require info on the modified-SMD interface
supported by the RM80. If anyone has details
on this interface, please let me know!
  
BTW, I'm also on the lookout for TOPS-10 and/or
TOPS-20 load tapes (or images thereof, or bits
and pieces... whatever I can find that will get
me closer to bringing this critter back to life!
