I have a fine old Stag PPZ modular EPROM programmer:
http://www.gifford.co.uk/~coredump/inst.htm#PPZ
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!)

Probably a stretch but wondering if anyone has any info (manual, pinouts,
service documentation) for a GNT model 3601 8-bit (1") paper tape punch.
It was probably better known in the CNC / automated machining world than
in computing but my hope is to resurrect it as a backup punch for copying
tapes I use with my ASR-33 and thereby save wear on the -33's punch.
The unit has serial and parallel interfaces on DB25 connectors but I do
not have any pinout information for those. The serial one I can probably
figure out.
Unfortunately, the unit is a little more sick than "works OK" seemed
to imply from the eBay seller. It has what I believe to be a power
supply problem because as soon as you try to punch all eight holes with
the front panel test button, the power LED dims and the punch jams,
apparently from lack of umph to complete the mission. It could also be
jamming to start with and that causes the power drop I suppose.
In any case, looking for any docs before I open it up and start digging
around. I have written to GNT without a reply so far.

I have an Apple Lisa 1 for sale. Yes, it has the Twiggy drives. It
includes the Twiggy systems OS disks (2), original Lisa 1 manual,
keyboard, original Lisa (rectangular button) mouse.
It works.
Excellent condition.
Normally I would not so brazenly hawk something but I need to raise funds
for an imminent move of the VCF archives.
I'm entertaining any and all offers. At a minimum, there should be three
zeroes before the decimal point.
Please contact me directly if you're interested. Photos and more detail
will be forwarded upon request.
Will ship galaxy-wide.
Thanks!

I think the machine you are thinking of might be the N* Dimension. The Advantage
still uses 10-sector floppies.
I've never seen the Dimension but vintagemicros on Ebay was selling one a while
back and had a picture of it. Apparently it was MS-DOS compatible.
Hey all --
Picked up an HP Integral PC. Probably paid too much for it but
something about a luggable HP machine with a plasma display running
HP-UX from ROM seemed irresistible. But I digress.
Has anyone archived the manuals for this thing? I've been unable to
find anything in my searches on the internet. Found some software
archives (and after lubricating the floppy mechanism I've been able to
make use of it...) but not much documentation. Docs for the HP BASIC
for this machine would be nice, too.
I've only played with it for a little while, but it seems like a really
neat machine. (Though it seems like this thing is just begging for some
sort of mass-storage other than the internal floppy and RAM. Anyone
have an HPIB hard disk for sale? :)
Thanks,
Josh

Looks like the message was eaten.
The pdf is on bitsavers for you to take a look at.
CHM hasn't issued a press release about it since we're still doing things
like trying to convert the interleaf formatted manuals to pdfs and are organizing
what we have.
What HP actually donated was materal from about the last 10 years of the product's
life (RTE-A, mostly). The earlier code is coming from other holdings.
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
about licenses.
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.
MS
many types of course. Generally speaking do the materials used in pc's from
the 80s fall into a single category? Everything is injected into a mold for
sure, from largish cases to tiny keytops. Would all this qualify as
polystyrene? Whatever the case, what's a good solvent (not necessarily glue)
that's useful for repairing big cracks or splits, to tiny hairline cracks. I
say solvent, and some glues can fall into this category, because it makes
more sense to reinforce the materials from behind to effect a strong bond,
and for cosmetic sake meld the item from the front, to obscure the defect
itself.
Many surfaces are anything but smooth. Has anyone tried, given they were
successful in melding the surface, in reproducing the look of the surface
surrounding it? Smooth surfaces can be melded then touched up lightly
w/ultra fine emery cloth and some sort of lubricant I would guess. But the
rough textures are a different story.
Hey all --
Got myself an HP 7980S 9-track drive (always wanted a 9-track drive...)
and accidentally mangled my one and only 9-track tape just after the BOT
marker (not sure what caused it, maybe the drive needs a bit of
adjustment...). So I have two questions: Where can I find a reasonable
replacement for the marker, and where does it go? I see the sense foil
on the part of the tape that got mangled, but I don't know what side of
the tape it was originally on...
Thanks!
Josh
P.S. The magical tape autoloading thing this drive does is the coolest
thing I've seen in a long time :).
