FIELD GUIDE TO Q-BUS AND UNIBUS MODULES

30 OCT. 1999

Introduction

This list is an attempt to coalesce all net knowledge on PDP-11 UNIBUS and Q-bus modules. It is designed to supersede all the various homespun lists floating around -- giving one solid source of information. An expansion is in progress: the Field Guide will now cover *any* Q-bus (or Q-22 bus) and UNIBUS modules, be they VAX, uVAX or PDP.

This list may always be found at ftp://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/hardware/field-guide.txt

This list may also be found on the following sites:

  1. ftp://ftp.village.org/pub/pdp-11/field-guide.txt -- Dworkin keeps a compressed version here, too.
  2. ftp://ftp.update.uu.se/pub/pdp11/doc/pdp11-field-guide.txt -- Johnny's site has quite a plethora of PDP-11 stuff, along with files/software pertaining to Pros and DECmates.

I will post this list as updates dictate to the PDP-11 newsgroup (vmsnet.pdp-11). At any rate, it will probably be posted in a terrifyingly irregular manner. It will be cross-posted to alt.sys.pdp11 and comp.sys.dec

To insure the growth and survival of this list, please do any of the following that you find appropriate:

  1. Send me your Q-bus or UNIBUS module list.
  2. Make corrections to this list and send them to me.

Just make sure you send anything you have to me. If you have relevant hard copy and you don't feel like typing it in, get in contact with me and we'll work something out.

We owe a great amount of thanks to Tim Shoppa, Johnny Billquist, Dworkin Muller and all others who maintain PDP-11 ftp sites. Also, a great deal of respect is to be accorded to *anyone* attempting to hook a PDP-11 to the net, or running one currently connected, for that matter. The same for anyone, anywhere who *doesn't* put a PDP-11 into the dumpster. Or the smelter. Etc. If you don't know what to do with it, call/email me -- I'll take it, or find a good home for it.
