hmm.. 
well, if nothing else, i am coming into posession of a mostly working
11/750 sometime in the near future, and i could put it on _that_ and
build microVAX support. whenever i someday do get this done, i will
make a microvax-bootable tape and submit it to the PUPS archive.. 
dont hold your breath though!! 

thanks for all the info so far to everyone! 

happy hacking
