Nice deal.

That's fairly normal.  Be careful about adding 2 hot drives to a SS20,
ventilation in the chassis is not great.  Also, you should have a small
fan mounted in between the hard drive bays and the CDROM/floppy bays, if
you don't then you can get one from Sun for free.  Call 1-800-USA-4SUN and
ask about the SparcStation 20 FCO.

You've got an SM71 CPU module in there.  Some SM71's have CPU's with -85
markings.

Use any straight through male/male mini-DIN 8 cable for the keyboard
cable.  Some shops sell these as serial switchbox cables.  Mice are
available used or new, you can get brand new optomechanical mice for $35
from Sun so don't go over this on used hardware unless you really love
optical mice.
