Here's what SG #65 had to say about the MPI VHS tapes for the '91 Series and a few other things:
Note the boo-boo at the start of what SG says about the first release from MPI - MPI actually released the first
2 hours in October of 1992, not the first 4.

I bought all the '91 Series MPI tapes at Suncoast and I have a copy of their DS mini-catalogue, but I don't believe there's really anything in it regarding the '91 Series. Though I will check once I can track it down...
