Introduction

This list is an attempt to coalesce all net knowledge on PDP-11 UNIBUS and Qbus modules.
It is designed to supercede all the various homespun lists floating around -- giving one solid source of information.

An expansion is in progress. In addition to PDP-11 UNIBUS and Qbus, the list will now cover other forms of the PDP-11 such as the Professional Series (CTI-Bus). Further, it will cover not only PDP-11s, but VAXen and MIPS systems as well (VAXen being available in both UNIBUS and Qbus forms, and MIPS machines in Qbus). The list will also begin to include chassis, mounting boxes, power supplies and backplanes.

For some non-Digital (third-party) disk and tape controllers, a list of reputedly compatible drives may be shown. This list is not exhaustive, and other similar disk and tape interfaces may also work.

This list may be found on the following sites:

1)   http://world.std.com/~mbg/pdp11-field-guide.txt
As of 02-Feb-2000, when I accepted the offer from the former maintainer to take over the file, this copy has become the official, most up-to-date copy. One thing people may note is that I have renamed it. This is because there is a similar file in the works elsewhere to cover pdp8 modules and options.
Comments and suggestions about the format and content of the file will be welcome at all times.
Please note that it may take some time for the *new* official file to make it to the mirrors mentioned below.
2)   On metalab.unc.edu, in the following location:
/pub/academic/computer-science/history/pdp-11/hardware/field-guide.txt
Tim maintains quite a large archive of other information, it is most definitely worth checking out -- Thanks, Tim!
3)   On ftp.village.org, in /pub/pdp-11/field-guide.txt
Dworkin keeps a compressed version here, too.
4)   On ftp.update.uu.se in /pub/pdp11/doc/field-guide.txt
Johnny's site has quite a plethora of PDP-11 stuff, along with files/software pertaining to Pros and DECmates.

This file will be posted on an irregular basis to the PDP-11 related newsgroups (vmsnet.pdp-11, alt.sys.pdp11). In order to ensure that this file is as comprehensive and accurate as possible, please don't hesitate to:

  1. Send any additions or corrections you may have to the file maintainer (currently mbg@world.std.com).
  2. Feel free to edit a private copy of the file to include your additions or corrections and send it (or a differences file) to the file maintainer.
Please be prepared to cite the source of any such information. This is to ensure that the file contains only validated information.
Just make sure you send anything you have to me. If you have relevant hardcopy 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, please contact me via email and we'll get the information out to people who would be interested in saving it.

We owe final credit and gratitude to Ronald Copley, who developed and maintained this list for numerous years. Thanks *alot*!
