  Mike Haas has has the setup disk. I gave it to him along with the P-IIIs
that I had. The setup program should also be one several of the machines.
FWIW I once found a third party setup program that worked on them. I don't
remember the name of it but I'm pretty sure that it was put out by a
company in Clearwater Florida that was later bought out by Quarterdeck. I
may still have a copy of it or the Compaq setup program. I'll look and see.
One thing to be aware of is that only the very first few drive table enties
match that used by IBM so be carefull setting the hard drive type.
