It's much worse for the KD32 (MicroVAX-I). Their memory is actually
on the Qbus, so not only do 32-bit transfers require two data cycles,

I love the KD32 anyway though. :) It was my first VAX, when I had
worshipped VAXen from afar for many years. And you know what? It
worked great. It was nowhere near as fast as my PDP-11/73, but the
additional functionality of VMS and a 32-bit CPU, and the GUI made life
so much nicer that I really didn't mind the performance hit. I still
have a MicroVAX-I...I should really get a working system disk for it and
get it running.

I also have a MicroVAX I (Currently housing a KA650, but I still have the
original boardset). It would be fun to get it running VMS -- the MicroVAX
I tops out at VMS 5.1, though. Where can one find media (and licenses) for
older versions of VMS?
