Realize that the program paid $0 for the satellite, since it was already
taken out of service from its original use.

I did manage to pickup an empty Microvax chassis. Its 9-slot, and I'm not
sure exactly what it is. VS31V-A2 is the model number on the back of the
case, but that sounds like a system model number. Anyway, the 128KW of
memory I have is plenty for what I need. Do I have to use the M8189 with
this chassis or can I use my M8186?
Thanks again,
