I picked up some Qbus cards yesterday. They seem to be

a MicroVAX II. However, one of the cards was, to me at least, a bit
unusual. It was made by a company called Webster, and it appears to
be a controller for SMD disks. I was not familiar with SMD disks and
had to look them up. I suspect this might be a little out of the
ordinary, and, possibly, an odd combination for a small Qbus system
to access such a physically large type of disk. Were MicroVAX IIs
used much with such disks? Is this a bit of an unusual find?
Two of my pdp-11s came with large SMD drives, albeit with Emulex
controllers rather than Websters. They're not uncommon. The
controllers typically use large drives to emulate two or more smaller
types - in my case, RM06s.
