How "not cheap" are they these days?  They are large enough for VMS
6.0 - I've done it.  OTOH, there wasn't any room left for anything
else, and I did have to trim off a few things to make it all fit, but
it does come up and boot on my rather-stock uVAX-II.

By even semi-modern standards, though, I'd agree with you that 154MB
just isn't that much room for later versions of VMS or Ultrix, but VMS
5.x and on down fit just fine, if that's what you want to run.

Agreed.  I managed to locate a Qbus SCSI controller a while back, but
I've had other DEC machines in the queue head of any MicroVAX work, so
I haven't been able to put a system together yet.
