I picked up some Qbus cards yesterday. They seem to be board set for 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?
I?ve used the WQESD/04 card on my PDP-11/73, if you don?t have SCSI, and have ESDI drive,
it totally rocks! If you have SMD drives to plug into this, you can probably make one
drive appear as several drives.
I?ve sense upgraded to a SCSI card, and use removable drive trays.
