I don't think so. I've built a 4.7 system running in a 11-780 SIMH
emulator :) I doubt 4.7 would run even in my 3300 (my oldest real machine).

  I was still running 4.7 on one machine (11/750) when I installed my
first 3100.   I'm pretty sure I installed 5.0 on the 3100 though.   I was
already running 5.0 on a pair of MicroVAX-3600s, and then 5.1 came out
very shortly thereafter.

BTW, 4.7 boots so fast under SIMH than at first I thought it had somehow
crashed or hung. When I got the "username:" prompt after pressing return
I was amazed :)

  Nice. :-)

  I bet 4.7 would absolutely scream on a 4000-90 if it had CPU support.
The difference between 4.7 and 5.0 on a 2.8VUP MicroVAX-III is like
night and day...I can only imagine it on a 4000-90, more than ten times
faster!
