3 Qbus modules

3.1 Introduction, warnings

As everything on these pages, the listings below are for informational purposes. I don't take responsibility for any problems, deffects, loss or damage caused by information derived from here. I don't quote full module specifications here, as there can be too many versions and revisions of a particular module. Full a larger database of the qbus (and UNIBUS, CTI, etc, too) modules please take a look at the Field Guide of UNIBUS/qbus modules!

3.2 Qbus boards: system components, options

A module can be referred to with the module number (which is in the format of Lxxxx-YY, where L is a letter (A, G or M), xxxx is a three or four digit number, yy is the revision #, for example M8047-YB) or the option name (which is normally in the form AAAxx-YY, where AAA is a three-letter "short name" or acronym, xx is a one or two-digit number (for LSI11 options it's mostly "11", but the same options can be used in a MicroVAx system), and YY is the revision ID (which hasn't got a trivial connection to the module number revision)). Examples: M8186 is KDF11-A and M7270 is KD11-HA. Of course there are exceptions: some modules have full names, without numbers, like the DEQNA (which is an acronym for DEc Qbus Network Adapter). Processors of the MicroVAX-class are labeled differently: KAxxx-Y, where xxx is a two-or three-digit number, and Y is the revision ID. An example is KA650-A or  KA42-B.

The module number is printed on the plastic handle(s) of the module, and is silk-screened on the PCB as well, but sometimes it takes a while to find it, especially when the letters became unreadable

Third-part vendor of course use other notations.
