For those with the finest tastes in old computers!

This is a web page devoted to PERQ graphics workstations, the first
definitive commercial graphics workstations. This web page, and
associated file archive, were created for my fellow PERQ Fanatics and
PERQ hackers, and others, who are mad enough to still share a common
interest in these fine machines.
Latest PERQ News:
This page was resurrected from its original home at Bob Davis's web
site after his sudden death, and in his honor. Bob and I did a lot of research on the Perqs, but he was far more persistent and dedicated than I. Without his efforts, much of the information on this site would have been lost or, at best, would be hopelessly distributed across the net. - Bill von Hagen
FAQs pertaining to PERQs
There are several PERQ FAQs which have been created, each
addressing different PERQ related issues, which can be found here.
These include: my original PERQ general FAQ in ASCII format, the HTML
version of the General FAQ, the excellently hackish PERQ hardware FAQ
by Dr. Tony Duell, and the very informative PERQ Programming FAQ by
Iain A. F. Flemming:
- The original PERQ General FAQ---ASCII text version.
- Hypertext version of
the PERQ General FAQ; thanks to Bill von Hagen for his work on HTMLing my
General FAQ! Remember, check back here for the most recent version of
the FAQ, which will remain in ASCII text format for now. :-)
PERQ Hardware FAQ by Dr. Tony Duell
PERQ Programming FAQ by Iain A. F. Fleming. A must read for PERQ
PERQ mini FAQ from Dr. Tony Duell
Other PERQish Documents
Read my PERQ
Historical and Technical Reference Guide, which is over
two-hundred pages long and still incomplete. It was written over a
decade ago and updated a little bit recently.
Read the PERQ CPU Technical
Reference Manual by Dr. Tony Duell---a PERQ hacker extraordinare,
a true genius, which is an excellent resource for understanding the
details of how the PERQ CPU works. An updated version from Tony is
More PERQish text file documents...
You may enyoy reading some interesting, useful and PERQ-related
Documentation that I wrote for the 3Prose document processing
software... it's most likely very incomplete; it's just what I wrote
while attempting to figure out how to use 3Prose so as to have
something to use with the PERQs for document processing---before I
found a copy of IDOCS Mint to use for typesetting documents. Does
anyone know where the original 3Prose documentation can be found?
Dr. Tony Duell's instructions for replacing PERQ 8" floppy drive with a 5.25"

- Xmas-lights-on-a-PERQ: How to use microcode to control blinking lights attached to the PERQlink port (From Dr. Tony Duell)
- centronics-interface.text: Plans for a PERQ GPIB to Centronics interface (again, more excellent hacking from Tony!)
Introduction to PERQ Microcoding (1 of 3 - yet again, more great PERQ
hacking info. from Tony who also wrote parts 2 and 3 below)
- intro-to-PERQ-microcode-2: Introduction to PERQ Microcoding (2 of 3)

- joke-played-on-perq-haters: A joke that was played on PERQ haters
- keyboard-codes.text: PERQ keyboard codes (I think you can guess who the
PERQ hacker was who wrote this (Tony)).
- obtaining-obsolete-amd-chips: An (obsolete?) article about where to get them
A song written by Tony explaining how a PERQ PERQs.
Before powering up a PERQ 2, for the first time, or if it's been
moved, or has not been used in quite some time, please read this
valuable info. from Dr. Tony Duell; it might very well save your PERQ
from a traumatic disaster!

PERQ Sound Files
A very few speak
(.spk) files for the PERQ: daisy1, phon1, sing1. Although the
creators of the PERQs were innovators in comptuter-related audio, the
PERQ workstations didn't benefit much from that and the audio quality
of the PERQs, as far as I can tell, is quite disappointing. The PERQs
also lack the necessary hardware for recording audio, and I understand
that external hardware must to be hacked onto the PERQs in order to
record audio on the PERQs.
PERQ Graphics Files
Some PERQ graphics files are archived here, such as:
PERQ TCP/IP Networking
Some TCP/IP software existed, but I've never found any complete working
TCP/IP software for the PERQs. However, I did find some non-functional
TCP/IP software for PERQs running the Accent OS on an old tape, which I hacked
on a bit in some spare time. Although I didn't get it to to much, it may
still be useful to someone.
for the PERQs. I forget what this is... unzip it, untar it, tranfer
the files to your PERQ, try it and find out; you may like it!
PERQdisk RT-11 Interchange Software
V1.0 and V2.0,
written by Dr. Tony Duell. This software allows one to read and write
PERQ "interchange" formate (RT-11) floppies on a PC.
Centronics and I2C drivers for the PERQ
Yet more useful software for the PERQs from Dr. Tony Duell! :-) Note: this
software is for the POS operating system.
Create POS G.6 Boot and Run Floppies
The following scripts are something I wrote for creating POS boot and run
floppies for the PERQs:
The Alt.sys.perq Archive
of the Alt.sys.perq newsgroup from the very beginning. Note that this
archive is not 100-percent complete. For about a few weeks, UUNET had
stopped carrying the a.s.p newsgroup, but I was able to save some of
the messages from another system (they're in the file named asp.digex,
or something like that). Also, there had been another UUCP
interruption and not all of the messages appeared to be arriving at
mystica, but I did attempt archiving them on another system; those are
in files named something like asp.umbc. So, aside from a very few
messages, almost everything from the early days of Alt.sys.perq should
be archived (hopefully!).
Most of the a.s.p articles are in groups of 100 messages; they
really should be sorted through, so as to note what the dates of the
first and last messages in them are.
A few PERQ games (for POS, IIRC):
Kermit for the PERQs
PERQ kermit sources. I don't recall which of the following is
what; they may or may not be quite similar: perqkermits.tar.gz
Assorted PERQ Utilities
- POS utilities that I wrote for chopping up and printing UNIX news
and mailbox files on a PERQ: the ChopPrint Utils V1.0: choppr10.tar.Z
- POS sed utility by Malcolm Shute: sed.shar.Z
- POS sort utility by Malcolm Shute: sort.pas.Z
Other PERQish Web Sites
There are also some other PERQ-related web pages on the 'net that
you'll most likely wish to visit:
Maydell's PERQ web page which contains some very useful
information, such as how to park the heads on a PERQ-1's 14" Shugart
- PERQ related software, firmware and
PDF's from Al
Kossow's excellent Bitsavers computer preservation archive.
- More to hopefully be added soon.
