Can you format one 1.44MB down to 720K? Early Laptops had 720 K diskettes.
Should be a format switch like / 720 or s:720

Subject: Honeywell Bull:Laptop
Hey,
Anybody familiar with the Zenith Data Systems line of Honeywell Bull
laptop computers? I just recently got one from a friend, complete with an
inkjet printer. I have pretty much all the specs/manuals that originally
came with it. No software. I booted it up for the first time and got into
the BIOS and fiddled with it enough for it to boot. It had DOS installed on
it. Does anyone know if that is the original OS, if not what was it? Now
here's the problem, when it boots now I can't get into BIOS or even into the
system monitor program. I have tried boot disks, nothing. I can't get it to
read the disk. hard disk or floppy. The boot disks I have tried have all
been 1.44 mb, do you think that maybe a low density disk would make a
difference, and if so does anyone know where I can get my hands on one?
Anyone have any ideas? Sure could use some advice!
Thanks,
Mark Belles

My concern is that something heavy may have been left on this thing for
multiple months/years and bent the plastic over time. I don't know this
for certain, but when I got home, the cover was broken (crack in the
clear acrylic panel at a corner, small bits broken off the opaque cover
adjacent). I'll disengage the heavy spring from the front ratchet and see
how freely this platten turns. For my tests last night, I was turning the
platten manually with a light grip on the feed knob and, depending on the
angular position of the platten, sometimes the platten would turn, other
times, my hand would slip on the knob. With the plattens exchanged, the
better unit turns easily and freely about the whole revolution and didn't
miss a single line feed in several feet of tests.

It is not stickiness on the ratchet teeth. I remove the platten and cleaned
each tooth with a cloth and blunt stick. It could be uneven wear.

I saw that the linkage could be disassembled, but at least this way, I didn't
have to readjust the tolerances. Fortunately, I think this is a one-time job.

An important tip. Many thanks.

I don't know of any simulators for the Univac 36 bit series. It would
be an interesting project, though. I wonder how much documentationf or
the original ERA machine still exists.
Exec 8 or it's descendents may be tough to find, though.
This is sort of off-the-wall, but does anyone know if there are any
emulators extant for my other favorite 36-bit machines - the
Univac 1100 series? Yet another one I might try to work on an emulator
for, assuming I ever retrieve my docs from my mother's house ... Of
course, I don't have a copy of OS1100, so I don't know what I could do
with such a thing....
(And, you can still buy a lot of this documentation, too - it's still
listed as available, and purchasable on-line, on Unisys's web site...).
--Pat.
OK... I found and fixed the lack of paper feed problem. It was
caused by there being a variable amount of force needed to turn
the platten depending on where it was in the rotation. In other
words, there is a flat spot or the platten itself is bent (I only
suggest this because one of the units may have had something
resting on top due to a bad garage packing job done by my former
roommates when I was out of the U.S. for a time). When I swapped
plattens between my two TTYs, the recipent unit turned over like
a breeze.
I did discover that you need to remove the print mechanism
>from the base to get access to a spring that's critical in
the line feed linkage. Fortunately, I found out the easy
way and not by busting something.
Now all that remains is the type cylinder/print hammer
retraction problem. I can type zeros all day and it
behaves nicely. Most keys, however, do not yield
satisfactory results. I currently suspect that the bar
that rides up and down on the 2cm-tall pegs (topped with
circlips) on either side of the type cylinder is gummed
up in some fashion. It moves up and down freely by hand,
but there is a bit of stickiness that I don't think
should be there. If I could figure out how to remove the
entire assembly, I'd swap it with the other unit.
At this point, I can manage exchanging entire assemblies
much more than individual parts. I did locate my wiring
diagrams (B-sized, blue covers, about a dozen pages) but
but not the grey maintenance manuals. :-(
Thanks for all the helpful suggestions so far. I've been
wiping and oiling (carefully) as I go along. I did get
those replacement print hammers from Western Numeric Control.
They are $2.50 each and just slip around the groove on the
bar face. I didn't know there was a groove there because
my old pad was clogging it. I wasn't experiencing any
problems with the sticky foot, but I do like to use the
proper parts when available.
Speaking of proper parts, I got some of the gear grease
on me from the helical-cut gears by the motor. I take
it that these gears take a graphite-bearing grease or
something similar. It certainly isn't axle or lithium
grease. Any ideas?
TIA,

They aren't bad machines (other than being prone to overheating). We just

Most of the stuff is new. I had *no* idea what was there. I thought maybe 20
racks...I made the deal on the phone without ever seeing the stuff. Even the
DEC guy had no idea what was there. I had the help of three others and we
all got beaten. I was told I could pick and chose but gave up and decided to
take everything - and that was much appreciated. I quickly went out and
rented more large 1-way trucks and we loaded them all -didn't even make a
dent in the place. I got back to TO with no idea where to put it. I know the
owners of a large apartment building here and rented the largest apartment
they had and rented it. My Dad donated the bottom floor of his home and I
filled storage units. I am trying to arrange for a large warehouse now.
>All of this sounds like more than one person's worth of work to me...

It is... My dad is 60 and almost had a heart attack. I had the flu going
down there. The DEC guy (who has a lot of experience with DEC stuff from
'68-90) was completely exhausted. He laughed at me when he heard I wanted
the TU56 drives.. he called them pure junk and really dislikes them. I don't
know what to expect next there.. visibility is only about 3 feet and I have
a long way to go... somehow I think there is a lot more than 14,000 pounds
of DEC stuff left there....
I am feeling a bit better today and hope to fire up one of those 11/20s.

Greetingz classiccmpistas.. I am in the market for a floppy drive
for the MicroVax II... the machine I wish to add to has a TK50 and
an RD54 (I think) and a Cipher 880 looking like a TS11.
Even if there are aftermarket units existing, I would still like to
get a DEC unit. I saw one on a nice uVax at one of the recent TRW
swaps here in SoCal, but its custodian wanted $300 for the chassis
and was rather offended when I suggested that he had got the decimal
point shifted one decade to the right.. ;o
Is anything other than the physical drive needed? Cards? Cables?
Drivers? VouDou/Santeria rites?.. (and if so, a good source for live
chickens in the LA area...?)
AND>>>> The last, very last TRW Swap Meet of the 1900's will be
held on Saturday, the 25th December, 1999, from 7:30am -> 11:00am PST.
PLEASE NOTE: that the venue has shifted slightly, and not just
due to PacRim plate tectonics. The previous lot has been sold, and
the New Venue instructions follow....
From the 405 (San Diego) freeway, take the Rosecrans exit west.
Travel west on Rosecrans approximately one mile to Aviation. Turn
left (south) on Aviation [under the curved Metrolink train bridge]
and proceed south on Aviation. Continue south another mile until you
pass the intersection of Marine Avenue. Continue south past Marine,
and the Swap Meet will be on your left.
It is now in the SouthEast quadrant of the intersection of
Aviation and Marine. PREVIOUSLY it was in the NorthWest quadrant. I
have spaces G22 and G24. If you are in the nieghborhood, drop by
and check it out. This coming Saturday most likely will not be the
most populous, but then again... the hardcore swappers will be
there, and Bah: Humbug!! to those with 'other' priorities.
Cheers and Best of the Season
HoHOhO
Here's something I'm willing to ship.
I've turned up three HP1000 pocket guides. These are small blue plastic
binders that seem to have quite a wealth of info on the HP1000's inside
(they're about 1.5 inches thick).
$5.00 each + $3.20 priority mail = $8.20 each. If you're local, you can
come and pick one up for $5 even.
Thanks much.

No. Wrong number of pins. This device has 40.

All PETs have a user port on the back that's an card edge. Original, static
RAM models have a card edge connector for memory expansion. Later models had
a pair of 40-pin pin connectors.
Given the apparent 0.1" spacing on this device and the number of pins, I'd
suspect that it's a TRS-80 device. I don't think it attaches to a Commodore
of any vintage.

I am in need of the RX01(753A9) and RK05(756A9) roms for the M9312
boot/term board. Can trade any of my "extra" roms, RL:(751A9),
RX02(811A9), DP:/DB:(755A9), or MM:(757A9).
I can probably also be talked into attaching one of my spare M9312's to
any of said roms to make this trade. Thanks.

Here's a brief list of stuff that needs to go, free to anyone willing to
haul it away:
(2) Sun 386i - case only, includes power supply. These look similar to a
mid-size tower PC case.
(2) ADDS terminals. These things are huge, but I believe they work.
MAG PC monitor, 14 or 15". No high voltage.
Assorted WYSE terminals for parts.
If nobody wants this stuff it will probably end up in the garbage very
soon (except for the ADDS terminals, which will go to Goodwill if they
will accept them). I live in Aloha Oregon, which is a suburb of Portland.

Fellow CLASSICCMP'ers,
I need help cleaning out, and I DON'T want to ship anything this time, so
this will be LOCAL PICKUP ONLY from Kent, WA (southeast of Seattle).
I'm not going to set fixed prices on anything because I would far rather
see it get put to use than sit on it until someone offers me something.
What I will say is that if you find something you like, and you feel like
making some sort of contribution, that's fine. If not, that's still OK.
Translation: Freebies with a donation can set up nearby. ;-)
With that in mind, here's a (mostly complete) list of what I want to get
rid of.
FAIR WARNING: If this stuff fails to move within the next month or so, I'm
going to drop it at whatever local metal recycler will take it, and/or rent
a dumpster from the local landfill.
I hate to do that, but I'm out of room, dang it! I need to MOVE this stuff!
THE LIST
Three DSD-880's with multiple manuals and diagnostic disks. Also included
is a DEC-produced VHS training video on how to service the beasties, and at
least one each of UniBus and Q-bus controllers for them (I say at least
because I'm not sure how many of each I have). I will also include rack
slides for the lot.
A Fujitsu 'Super Eagle' SMD hard drive. Big rackmount beastie, spins up,
comes ready, runs wonderfully quiet for its size. I've not tested it
in-depth, but I see no reason why it should be anything but functional.
Includes rack slides (nice aluminum-alloy ball-bearing ones, no less).
Two Cipher 880 series front-load 9-track drives. One is a straight Cipher
drive, the other is an OEM unit they did for DEC (a TSV05 if I'm not
mistaken). I can also throw in at least one Qbus controller card, and at
least one set of rack slides.
A mid-size box full of 8" floppies with various software, including old
versions of RT11. There's also a bunch of misc. DEC manuals. The only rule
I'll make on this pile is that if you want any of it, you have to take it all!
Two MicroVAX 2000's. One has been set up by me to be a handy formatter for
those RD52's and RD54's that you Just Can't Find the Service Diagnostics
tape for. I did this by making a special ribbon cable for it that's about
twice as long as the original.
This next item should be of interest to those who want to do graphics on
the MicroVAX II and III: I have at least a pair of complete VCB02 graphics
subsystems. This means two each of the controller boards, four each of the
4-plane color boards, two BIG 19" RGB monitors, cabling, keyboards, and
'hockey-puck' style electronic rodents.
While not exactly computer-related, there might be some of you who have
wanted to install an old 1A2 key telephone system in your place. Well,
here's your chance! I have a Western Electric 551 series "shoebox" key
service unit and some line cards to go along with it. You can route up to
four lines through this beastie: All you need are some 25-pair cables and
some keysets to go with it.
I'll also be getting rid of a pair of rackmount SCSI drive enclosures.
These are nice ones made by Control Data. The drives mount in special trays
which then slide in the front (they hold two drives each) of the
enclosures, and there are thumbwheel switches on the backside to select
SCSI ID for each position.
There may be some other bits and pieces that I'll find in the process of
cleaning out, but that's the bulk of it. If you're interested in anything,
please drop me an E-mail note and we'll set up a meeting.
Thanks in advance.

Okay... I am still in extreme pain (a nail went into my head at this site,
not to mention other damage from being squashed by some stuff) but here goes
an attempt to list what's on the first truck (I still have at least 3 more
shipments to do):
Hardware:
PDP-1 software, 40 trays, all the DECUS stuff too, I expect a new or near
completed PDP-1 as we get through the building
Classic-8 rack mounted, looks new. -Already spoken for ... I promised this
to a friend a few years ago.. I will get more of them.. I hope.
PDP-16

TU56 prototype
spare new unibus boards (700+)
spare new CPU boards (a few hundred)
expanders filled with >????? (10+)
new backplanes/font panels for PDP-8Ls,PDP-11s,LSIs, peripherals.. etc..
lp25 band printer (cool!)
various stands and racks used in pictures in DEC photos
PC05s, etc...
TC11
TC01
RK05 track writer and exerciser (cool)
I know there is a lot more but I can't think of it right now....
Manuals (extensive... far beyond what I imagined):
Microfiche for every device, peripheral, board made by digital from 1965 to
1978 (mostly PDP-8,PDP11,LSI but I did find a box full labeled PDP-10)
15 boxes of PDP-8 manuals for everything you could think of including the
338 display
too many boxes to count of PDP11 CPU/Peripheral manuals
Every DEC handbook ever made
Internal DEC manuals "DEC Tips" and training material for the
8/s,8/I,8/e,etc...
DEC module bible -1984 :-))))))) , in print and disk, and tape.. sweet..
every module in order with description and unit installed in...
Software:
234 trays of PDP-11 paper tape software
40 trays of PDP-8 paper tape software
a few hundred mag tapes
96 dectapes (both 8/11)
hundreds of floppy disks
[I have told that I will have every version of every piece of software both
in beta and released in every format PT,dectape,magtape,rx01,rx02.. I still
have a huge room to clean out filled with RSTS,RSX,and RT11, OS/8]
65 RK05 packs, both PDP8,and 11, LSI
Tools:
Extenders
KM11s
dual KM11 extenders
serial handheld tools ??
portable microfiche readers
calipers and gauges
too many things to list....
Upgrade kits and spares
Many TU56 parts (new wheels, etc)
Printer parts from hell.
disk/tape cleaning kits, new heads,filters, etc...
Coolest stuff (stuff I will keep):
TC11
new TU56s
LP25 :-)
microfiche (even PDP-8 schematics, schematics for every module made in order
>from A-series to Z) :-)
Stuff I saw but have to pull out next trip:
300 more boxes of manuals
200+ boxes of software
PDP-11/35s
PDP-11/05s
PDP11/20s
PDP-11/34s (all old style)
PDP-11/03s (all with RX02s)
LA30
Decwriter everything.....
VT100s 20+
and....
there is the "unknown" building where everything PDP-11/20 and before
went... I will try and clean a path to it next.. I looked through a window
[visibility is 3 feet] and saw a bunch of R-series backplanes, 11/20s,
11/15s, and what looks to be more PDP-8Ls. (again.. stacked 10 feet high)
How I got the nail in my head? I spoke to an old DEC at the warehouse.. He
told me they stacked old pre PDP-8 stuff (light) in the rafters... I climbed
up and saw out of the corner of my eye a box labeled "R107"... thinking
about my PDP-8/S I dove for it... only to have a nail take a chunk out of
me... while recovering on very *weak* beams I dropped down a 1100 flip chips
and the PDP-1 software. There is still alot left up there but I was in a lot
of pain and the trucks were full.
19 hours to load (two days), 12 hours to unload... A lot of this stuff will
be for sale/trade. An inventory is almost impossible as I expect a few
thousand UNIBUS boards, a few thousand flip chips, at least 300 core memory
boards, now, at least 75 minis, manuals, paper tape when done. I don't know
what I am going to do yet. [I did not expect this].. Maybe a super
Keyways???. I did rent the largest apartment I could find and filled it. I
also have two storage units filled and my lab. AT&T gave me the bottom floor
of one of their buildings to use but.... [you'll never guess].. it's filled
with MicroVAX's and PDPs from a company they bought out a little while
ago... I get that stuff next month.
Funniest part: I loaded the trucks sooo heavy that every time I turned the
corner the back bottomed out and ground down the tires. The border did not
stop the trucks... let me through without taxes.
I will try and put up picture in the next day or so on my site... I am
really sick right now and am trying to recover for XMAS.
OHH, by the way.. I got a call today and have a warehouse to go to that has
a ton of HP-2 stuff, software, manuals, boards, and wang tube stuff,
also...????
Sad part is I doubt I will be able to find any more *cool* stuff after
march.. Most of this was scheduled to go to the dump in March and most
companies are pitching anything non-Y2K complaint over the next 3 months.

Take the money and run.
GRiD Compass: 1982 (Sometime in the fall)
Sharp PC-5000: 1983 (March)
Gavilan: 1983 (March or April)
TRS-80 m100: 1983

I don't know what Zenith's first clamshell was, but I'm pretty sure it was

The UPS ship rate is higher at the counter than it is for pick-up. It costs $4-5 more
to ship a 50 lb. package cross country from the counter than it does for a pick-up.
That about offsets the pick-up fee. Isn't as favorable for lighter packages, obviously.

well, the lcd screen for the //c only sits on top of the computer and does
not fold down and is not integral with the rest of the computer so it really

Just a little trivia question I thought I'd ask everybody, here it is:
Who (by company, that is) invented the first "clamshell" laptop? I am
tempted to believe it is either GRiD or Zenith Data Systems that introduced
this style, but if I had to, I'd lay my money on GRiD.

Suppose I have this account on an XKL-10. Now suppose I want to transfer
some freeware off of it. How do I preserve the 36-bitness with ftp? Do
I just use binary mode for executables and TENEX mode for text?
I only ever got to dabble with the DEC-20 at OSU before it was gone. I was
never a whiz with it. Perhaps there's a FAQ for TOPS out there?

It depends on what value of "normal" you have :-). Only the very oldest

common in collections of scrounged RQDX3's!

Hmm - I think that instead of attributing that to my profound insight, it

The Item: Two 5 1/4 inch floppy disks with text documents stored by an

You'll have to be more specific about what sort of floppy drive
that you want to hook up. 8 inch? If so, RX01 or RX02? In this
case you'll also need a RXV211 or clone controller in the Q-Bus
backplane. 5.25 inch? If so, RX33 or RX50? In these cases you'll
just attach to the existing RQDX3/breakout box. 3.5 inch? If so,
you'll need a third-party Q-bus controller to run the drive, unless
you get your hands on a prototype RQDX4 :-)

I stand corrected. A slightly more accurate measurement gives pins within a row
at 2.75+/-0.01 mm, between rows 3.00+/-0.10 mm (the latter more likely to be
less than more).
My mistake arose because the row of 13 pins on a DB25 measures almost exactly
1.3 inches, pin centre to pin centre. How could I do such a thing? There
really is no excuse!

They did 40,000 items of one sort or another. LQP02 switchboxes were one.

Your pinout (connections) are munged. I'll bet you used pin1 from the

Unfortunently, I think it's impossible, as Apple disks used a totally
different recording format than PC disks do/did. AFAIK, the only
alternatives are an original Apple box or a Mac decked out with the
Apple 5.25" drive.

This is an all too common question and has been answered before. the only way
to do it is to use one of those apple // emulation cards in a pc, such as a
trackstar card.

Yes. Two ways:
1. Use a specialized "free-format" floppy disk controller in a PC-clone.
Typically requires a non-negligible $ and time investment.
2. Hook an Apple ][ with disk drive to the "output target" system
via a serial cable.
Really, the best way to do this (and I've been doing this for
a few decades now!) is #2 - the best Apple ][ floppy disk controller
for a PC *is* an Apple ][!

Sure, it's largely flat ASCII with some escape codes thrown in (and, IIRC,
it has the high bit set through most of the text, very reminiscent
of Pr1me text files.) Image the floppy, dump the files, no big deal.
