The 8/L, ASR33, DF32 disk emulator project has been sold. Thanks
for all your interest (and offers). Anyone who wants the DF32
emulator schematic and artwork, I can email you a copy. I hope
someone can take my "first draft" and make a useful unit for those
who are interested.
I have a working ADM-3A that I may want to sell also. It has a
homebrewed lower-case 2716 ROM (thanks Steve Loboyko for the font
files). I installed the "optional" parts for current loop on the
main PCB, and used it with the 8/L. The only thing that's missing
is the little aluminum panel covering the dip switches.
Any interest? Same deal as before, please email offers, "sealed
I have a fine old Stag PPZ modular EPROM programmer:
It takes plug-in EPROM (model Zm2000) and PAL (Zm2200) modules, called
Z-modules by Stag. I've recently acquired a new module, Zm3000, which
looks like a more recent EPROM module. The chips in the Zm3000 are
date coded in 1993, whereas the Zm2000 is nearer 1988. The PPZ main
unit contains a 6809 CPU and a small CRT display.
Does anyone know anything about this system? What about other Z-module
types? In particular, should the Zm3000 work with the PPZ, because I
currently get an error message "Incorrect Mainframe"?
Thanks in advance for any clues! (Virtually all I get from Google is a
link back to my own web page!)
Anyone here have the speech module for an IBM PC Convertible
they want to get rid of?
I just got one of these laptops & was hoping to score one.

Back in 1998 (actually more like from summer 1997 until summer 1998,
i.e., the 1997-98 school year), before I started Quasijarus Project,
I was searching the World high and low for a copy of the 4.3BSD tape
set. That was before PUPS got its momentum with getting the $100
"Ancient UNIX" license deal from SCO, and more importantly, getting
people interested in preserving and working with Original UNIX, and
at that time the entire world was basically in a conspiracy of
anathema against original Bell/Berkeley UNIX, everyone just wanted
it to stay buried in its grave and not come up.
Getting a copy of the 4.3BSD tape set seemed next to impossible.
www.berkeley.edu was shockingly silent about the fact that Berkeley
UNIX aka BSD, UC Berkeley's greatest accomplishment in all of its
history, ever existed, much less saying how to order a tape. Finally
I found a phone number and a couple of E-mail addresses for some
office at UCB that was apparently kept for sending out tapes after
CSRG itself was gutted. The office was basically a voice mailbox and
a couple of E-mail addresses, with the two people who were actually
supposed to get those E-mail and voice messages being away somewhere
in San Francisco and taking a few weeks to answer inquiries.
Finally they got back to me and told me to send a check for $2400 for
4.4BSD and $1000 for 4.3BSD. Ouch! And of course some murky business
At that time, however, I attended Case Western Reserve University (CWRU)
and had a semi-staff relationship with their computer science department.
I realised that the university must have had a UNIX source license from
back in The Days, and most probably had the actual 4.3BSD tapes at some
point as well, especially given that the old-timers told me that they
were indeed running 11/780s before. But again the conspiracy of anathema
was working: everyone had completely forgotten about it, and no one on
the entire campus even knew that the university had a UNIX source license
(and old-timers confirmed that indeed there was one).
When spring 1998 came around, PUPS was making its debut with the $100
license deal from SCO. I didn't care so much about license stuff, but
it meant a resurgence of interest in Original UNIX and a community of
people involved with it, something that was completely lacking only a
few months prior. I wanted access to the PUPS archive, and I wanted to
use the university's license rather than fork over $100 for a personal
one. The only issue was *finding* that license. Then I got a bright
idea: since the license agreement was between CWRU and AT&T, there must
have been copies of it on both sides. If CWRU had chosen to forget
about the license they once paid big money for, how about if I dig up a
copy of the license agreement from AT&T side? So I asked SCO's Dion
Johnson about it, and lo and behold, a few days later a copy of CWRU's
original UNIX license agreement shows up in my box in the computer science
department mail room! Warren Toomey got another copy and soon I got an
overseas fax from him with passwords for his PUPS Archive! Whoo-hoo!
But I still needed 4.3BSD. It wasn't in Warren's archive since they
were still PDP-only at that time, and me holding a copy of my school's
AT&T UNIX license agreement didn't help convince anyone I knew who
might have had 4.3BSD tapes to share them with me.
In late 1997 I got myself an office at CWRU, it was the CES department's
computer junkyard room. I was quite happy, a room full of classic
computers was the best office I could get. It was actually two rooms,
411 and 412. Only 411 was accessible from the hallway, the entrance to
412 was inside 411. Both rooms were filled with classic computer gear,
but 411 was a little less full and actually had some room for a desk and
was usable as an office. 412, on the other hand, was *completely* filled
with classic computer gear (mostly Sun 3) and it was difficult for a
person to make it through to the end of the room. At the very end of
room 412 (the end opposite the entrance door from 411) there was
something that looked like a plastic curtain or plastic window blinds.
The architecture of that building was really intriguing, the kind one
finds only on good old university campuses, and I couldn't really tell
if there was supposed to be a window there or not. I just never gave
it much thought, and it was too difficult to climb over all that Sun 3
gear in the way to see exactly what it was.
On a shelf in room 411 there were some magtape reels, and I thought
that if they ever had 4.3BSD tapes, they ought to be there. But I
looked through all the tapes I could see and 4.3BSD wasn't there. Bummer.
Then one day in summer 1998 I came to work in the morning, went up
the stairs to my beloved Computer Engineering and Science department
4th floor, went to the end of the hallway to my office, and got in.
I turned on the lights and per my usual habit, peeked all over the
room to make sure all the fun classic computers were still there.
And lo and behold, at the very end of room 412, where I previously
saw those plastic curtains or window blinds or whatever, I now saw
two racks full of magtapes! It turned out that the plastic "curtains"
were actually vertically sliding doors (kinda like garage doors) of
two huge magtape cabinets! Another staff member must have had a need
to get some old magtape and didn't close the cabinet after he was done.
With trembling hands, I raced there and started looking through all
the tapes. And sure enough, in a few minutes I found all 3 tapes of
the 4.3BSD 1600 BPI distribution.
I spent pretty much the whole year prior to that moment searching the
World high and low for 4.3BSD tapes when they were sitting the whole
time in my own office! Now that's a "Duh!" moment.
Have a working Intel Above Board Plus 8 with 2MB RAM and would like to
populate it to the full 8MB. It will take 120ns or faster 1mbit chips
-- but where can one find that kind of thing nowadays? Are those still
commercially available or am I going to have to scavenge them from
Manual lists acceptable part numbers like:
...etc but google searches haven't been very fruitful (that is, the
pages returned when I search for IC part numbers don't return vendors
with plain pricing/availability info).
I just want a few tubes of these to populate the board, I'm not looking
for a box of 'em :-) Any pointers?

A note to all 2.11bsd users:
Some time ago I looked into running 2.11bsd on systems without
floating point unit. The release notes state that this is untested
and unsupported, and indeed it didn't work.
Robin Birch some time ago fixed part of the issues, see patch 434,
but still the kernel paniced when the very first program was started.
I managed to localize and fix the problem in sys/pdp/mch_fpsim.s.
Steven Schultz right away issued 2.11BSD patch #445. All patches
up to and including 445 are provided by Steven under
A patch level 445 system will now boot on simh for example on a
set cpu 11/70 nofpp 4m
configuration and work just fine, albeit a little slower.
It should thus also work on a real 11/70 without FPP. I heard
of some 11/70 with non-working FPP's, so this maybe good news
for the owners.

As many of you know, the venerable Mike Quinn Electronics in San
Leandro, CA (down by the Oakland Airport) closed last Saturday with
virtually no advance notice. If you're in the San Francisco Bay Area,
you know Mike Quinn is the one of the very last of the nitty gritty
electronics salvage shops left, with an emphasis on gritty.
I stopped by today, and mentioned to Maurice, the owner, that a lot
of people would have liked to have had one last shot at a visit. So,
he has extented an invitation to y'all to visit next week, Tuesday
through Friday February 7-10, 2006, during normal business hours, for
one last shopping spree. He is trying to find a buyer for the stock
in the store. This is almost certainly the last chance to visit. If
you can, it's worth doing whatever you have to do to make the
pilgrimage. Buy some stuff to thank Maurice for keeping it going all
There are zillions of connectors and components, heaps of
transformers and power supplies, scads of cables and keyboards and
monitors and other PC junk, a jet fighter console or two, a couple of
early 80's HP desktop computers (the ones with built-in BASIC, can't
recall the model numbers), lots of relays, and much more, all
arranged in an archaeologically interesting and un-seismically-safe
way. If you need it, they have it, and they might even be able to
