  I forgot to mention that AFAICT, DEC uses custom microcode with these,
because when I tried to use the version "I" microcode off Adaptec's
site, even OpenVMS 7.2 wouldn't install anymore. My experience with
Digital Unix and OpenVMS 7.2 on an Aspen Alpine and a 164LX tend to
support that idea. What I'd really like to find is Compaq's archive
stash. If any of that still exists.

  I didn't want it when I got it. It was part of a package deal, and I
already have more Apple stuff than I ever intended to have. I find
MacOS not only extremely irritating, but strangely unavoidable.
