QBUS peripherals

QBUS peripherals were used in both PDP-11 and VAX systems; the QBUS was the primary bus in many of the former (and the MicroVAX I of the latter), and the I/O bus in most of the low-end models of the latter.

Many were available from DEC, and as was canonical for DEC machines, from other organizations.
