Can someone explain how to use AT 1.2MB floppy drives on an RQDX3.
I have this wilde hair that I want to try to load NetBSD or Ultrix
from floppy as an aside on one of my MVII crates.  IFF the hardware
is compatible, and I think it is, even though the floppy formats
are incompatible with the old RX50 things, all I need to do is mate
up a 34 pin dip header cable off the back of the backplane firewall?

What ID and jumpering is required?

Thanks

Bob
