Introduction

This list is an attempt to coalesce all net knowledge on PDP-11 UNIBUS
and Q-bus modules. It is designed to supercede 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 on metalab.unc.edu, in the following
location:

/pub/academic/computer-science/history/pdp-11/hardware/field-guide.txt

This list may also be found on the following sites:

1) ftp.village.org in /pub/pdp-11/field-guide.txt
   Dworkin keeps a compressed version here, too.
 
2) 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.

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
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, call/email me -- I'll take it, or find a good home for it.
