I've updated my Wang 2200 emulator to version 1.1. It has been about
six months since the last update.
This release adds two signficant features:
1) disk support. You can now plug in disk controllers, each of
which can control two drives. Drives can be any legal size, and the
timing can model that of 5.25" or 8" floppies, or hard disks (even the
interleave factor is modelled). You can optionally turn of the emulated
timing and make it run as fast as possible.
2) when an error message is displayed on the screen (which are just
two digit codes), double click on that line and a detailed explanation
will pop up. the explanations come directly from the Wang BASIC manual.
Adding the first feature was a lot of work. I started with the
microcode dump from the disk controller and a document describing the
microarchitecture (believe it or not, the 2200 has a 4b ALU and the disk
controller has an 8B ALU). From there, I wrote a disassembler and
studied the listing until I thought I understood the protocol. I
implemented it and ironed the wrinkles out of my assumptions.
Please have a look if you are interested.

*sigh* I wish there were more collectors out in Western Canada
(I'm in Calgary at this moment...occasionally in Vancouver & Saskatoon)
Whenever I search for old stuff (even just to look at and admire
such as in a museum it's always in Ontario (or further east) which
ends up being a two-day drive for me.
There's been lots of PDP-11 stuff recently on ebay.ca, but it too
is all in Ontario
I'd LOVE to to see those Kenbak-1s...but they'r too far away.
Oh well...
Dear Bob;
I am puting together a history of low power systems and came
across the RCA 1802 as maybe the earliest single chip CMOS
processor (along with Intersil 6100). I am trying to figure out when
the RCA ICAN-7029 appnote was written and wonder if it is in
your Microsystems Manual or if you have other databooks.Thank
you.
Best Regards,
Brian
Fred, Thanks for the heads-up. I do in fact still have a couple of *brand
new* CFX-40s left for sale at $500 each. They are absolutely brand new,
unused, never worn, in the original box, with manual and hang-tag. I also
have *one* used CFX-40 in very good condition (it has a crack in the side
of the case which has been repaired with cyanoacrylate glue), which is
fully functional (everything works properly, including the light), has the
original band, and which also includes the original box, manual and
hang-tag for $300. For either new or used, add $10 S&H (incl. insurance).
Email me directly if interested, I can send pictures and references if
necessary, Scott.
The HP 5423A is a vintage piece of test equipment with an embedded HP-MX
processor. If you happen to have a master or copy of the "control" tape
(system tape) for the critter, I'd really appreciate borrowing one so I can
make a copy.
Thanks,

I came across a decent stash of 9 track reel tapes during my clean out.
(4 cases, so maybe 50 or so of them)
A while ago, I sold or gave away (don't remember) a whole bunch of the
write protect rings for them. So I'm wondering, do those rings stop you
>from writing, or enable you to write when installed? I want to try
selling the 9 track tapes on ebay, but I want to make sure I specify the
correct status of the rings (that don't exist).
Also, are these safe to bulk erase with an electromagnet? So far none of
them have any data on them that I am worried about erasing, so I'm not
planning to bother... but I want to know if it is safe or not in case I
find one I need to.
And finally, are all 9 track tapes the same? These were used on our
General Automation Zebra machine. So will they work on any machine that
needs 9 track, or only on other Zebras?

Stan,
I've done some calling around and emailing. Casio has four distributors
that they send replacement parts to. None of them have the case in stock.
The last time a case was sold from Casio was on April 30, 1996. It was to
an individual, not a distributor.
The CFX-400 case with key pad has two part numbers. The first is 73081910.
It was later changed to 73081928, but it is the same part and description.
There are two parts still in production and available from Casio that you
may want to consider buying. They are the rubber backing seal and the LCD
(not the module, just the screen).
Good Luck.
I finally started refurb on a drive rack, a nice low-boy HP 29425 with wood
top. It's my first HP drive project that uses the 13037 subsystem, with a
7906 drive. This is so I can finally start going through all the 7905/7906
drives I have and figure out what works and what doesn't.
After going over the drive very carefully with a fine tooth comb, checking
all the power supply voltages, test point voltages, etc... the moment of
truth - hit the load switch, then turned it off just before the heads
loaded. Did this a few times to make sure the blowers sucked any stray
particles up and to the filter before letting the heads load. Finally I let
them load and got a nice clean (fortunately quiet) "drive ready". Which
leads me to my question...
In testing unknown drives and cartridges... one never knows if the heads
will come out the first time and shred against the platter. I've never been
standing around when a head crashes, but I envision horrible grinding noise
as metal shards shoot everywhere inside the drive. Is there anything I can
do other than visual inspection, before spinning up an unknown drive and
letting the heads load, to help alleviate the bad possibility of a crash on
a drive that probably hasn't been used in 25+ years?

After several hours with the 11/84 last night, it appears that I'm in
the same boat as Gunther with respect to the Unibus terminator.
First off, in *any* configuration with an M9302 Terminator in A-B of
the last slot, the CPU hangs at boot at LED 77. I have plenty of G7273
NPG-grant continuity cards, as well as non-NPG knuckle-busters. Which
they are.
I'm pretty sure my configuration of the card cage isn't right.
Here's the original layout (forgive any misalignment in the drawing -
Mozilla apparently translates tabs to whitespace, and not correctly):
A B C D E F
|| M7677 - 11/84 Monitor ||
|| M8190-AE - CPU ||
|| M8637-BC - 1MB ||
|| M8637-DF - 1MB ||
|| M8191 - Unibus PMI ||
|| G7273 - NBPG ||
|| M7860 General Dev Interface? ||
|| M7860 General Dev Int. ||
|| M7819 - 8-Line Async ||
|| M7819 - 8-Line Async ||
|| TCU-150 - Custom serial splitter, NPG unkn. ||
|| M8526 - RX211 ||
|| UniB OUT || M7258 - LP11 Printer Int. ||
The TCU-150 is entirely undocumented except for a couple of invoices
for etching and assembly. It's supposed to be part of a system of
splitting an available serial line into multiple comm channels, but
that's all I know. For whatever it's worth, the original configuration
map on the lid of the system unit is accurate, and appears not to have
been altered, so I'd guess that the backplane is in its original state, too.
What I want is some variation of this:
A B C D E F
|| M7677 - 11/84 Monitor ||
|| M8190-AE - CPU ||
|| M8637-BC - 1MB ||
|| M8637-DF - 1MB ||
|| M8191 - Unibus PMI ||
|| M7486 - UDA50-A ||
|| M7485 - UDA52 ||
|| M7521 - DELUA ethernet ||
|| M8526 - RX211 ||
...although the DELUA isn't strictly needed. Even without the DELUA,
with the last 5 C slots populated with non-NPG grants or with G7273 NPG
grants, I don't get a reasonable response from the RX02. And as I said,
with the terminator installed, the box just hangs at powerup.
Can anybody tell me what I'm doing wrong?
Doc
Hallo Peter,
Yes, I have the wanted service manual of the Persci 299 drive somewhere in
a carton box.
Let me know if you still needed!
I used to repair these drives, and have some spareparts left like heads,
bulbs for the sector indicator (plastic black box) and some very hard to
find driverchips for the voice-coil wich I found in Bangkok.

If you should ask me to send a copy of Quick Basic, please be sure you can
receive it. I once sent it to a fellow behind a firewall and the firewall
bounced it. The set contains executable files and they could be
dangerous (Indeed, you have to trust ME not to insert a virus, but then
again, I don't know how! Don't even want to know how.)
Bob
When I wanted a copy of QuickBasic, not yesterday, but not so long ago, I
was able to download it from the Internet. As far as I know Microsoft has
released it for all to use. It is, however, not supported in any way.
You can find the interpreted version on some versions of MSDOS; I believe
DOS 5 contains it. What I got from the Internet was QB4.5 and a
professional version 7.X.
If it has ceased to be available I can send a copy if it has really been
opened to public distribution. I must just find a set of diskettes. I
know I have 4.5 but I am not so sure I can locate QB 7. If I get too many
requests, I will ask those getting it from me to fulfill the condition of
passing it on to others asking!!! Shareware=share the responsibility!
Bob
PS Warning; stay away from those versions of Visual Basic offered as free
on CDs. I loaded one of these, it gave me NO WARNING as it told me I
needed some components it would have to download from the Internet and then
it dumped a bunch of junk on my hard disk, including substituting a new and
unwanted "Desktop" and changed my Internet browser to something else, even
less wanted than the new Desktop. Windows was never normal after that.
Eric,
You hit the head right on the nail ;-) All kidding aside, that is exactly it!
thanks to all for your input.

What's the problem with you guys??? The Unibus is really simple to get
right. :-)
One thing you should know about the 11/84 is that you don't use wire wraps
on the backplane for the NPG slots in the CPU box.
The M7677 (MDM) have NPG switches for all card slots instead. Go to that
card and check it out...
Second. The 11/84 must have a minimum load on both the PMI and Unibus. The
minimum load module (MLM) is M7556. Since you have two memory cards, that
MLM is not in. But depending on the configuration of the Unibus, you might
want to have the MLM in there. However, I don't think you have a problem
here, since I suspect that if the machine powers up, that aspect is ok.
It would be nice to hear how Gunther is doing. I'm very sporadic on
classiccmp though. If you need help on pdp-11 stuff, I'd recommend you
post to info-pdp11, or alt.sys.pdp-11 (or whatever it's called).

---------------------------------
I am having a similar problem, but my system does not have an M7677.
Mine is an 11/84E. The CPU is in slot 1, memory cards in slots 2 and
3, and the Unibus adaptor in slot 4. 5 and 6 are empty, 7 and 8 have
the UDA50, and 9 has a printer card of some sort. For mine the NPG
grant jumpers are actually on the bottom of the backplane. I have set
them for where the boards are not.
I had believed this system to be configured as working, but it is not.
It has a second backplane but had no M9202. If I put the terminator
in slot 9 of the primary backplane it hangs. I know the UDA50 needs
the NPG out. I will have to examine to see if the printer card needs
it or not. I would guess the Unibus adaptor would not?

Hi,
I spotted three old HP disk (and disk/tape) drives
indoors at a salvage yard (Heillman Salvage) in Atascadero,
California(about 170 miles south of the SF Bay Area):
HP 7914
HP 7908
HP 7911
They didn't look like they're in immediate danger of
destruction (they're currently working on breaking up a Cray 2 ...
no, they didn't have the entire machine ... apparently,
the Computer History Museum got the CPU, and Heillman got most of
the rest).
The HP drives were a bit dirty, and I have no idea
of the price. The phone number is 1-805-466-4893.
Also spotted (outside): carcass of a Lisa (3.5" drive, no faceplate),
a badly burned HP 9845, a probably stripped CE control panel for
some 12 bit computer (no brand name visible, had a rotary dial with
a semi-transparent plastic disk in lower-left corner of
panel ... couldn't get close enough to read anything).

Anyone know if anyone still makes DC-100 tape cartridges any more? I'll
be getting an HP-85 soon & I want to find a source for blank DC-100 tape
cartridges.
My searching so far has turned up nil, but maybe I'm just looking in the
wrong places.
Any help is more than welcome.

Hi,
I received the following two-part email this week...
A free 9835...
...
I moved up to an HP 9835.
[It's in Canada]
...
Now the good news, I still have the 9835 in my basement. I think it's
still close to being
functional, it turns on without clouds of blue smoke but the monitor
appears to have given up so no way of seeing if it is really booting
up. I'm not sure about the tape drive?
If you could locate a monitor, maybe you could get a functioning 9835.
It's free to a good home
And, the project:
I have been looking everywhere for anyone who might have a functioning
9835/45 because I still have about 10 tapes with thousands of pages of
HP BASIC that I would love to off load to some form of modern media in
ASCII and translate into modern BASIC. If you could help me with this
problem I would even pay the shipping of the 9835 to you, if you are
interested?
Anyone interested, reply (offline) to me, and I'll pass the contact info
on to you.
thanks,
Stan
Hi, I'm still wondering if I'm left the only one actively messing
around with a VAX 11/780, because all the help I get comes
>from PDP-11 people ... but that's adequate since I am still
debugging the UNIBUS.
I now made sure the NPG line is interrupted under the M7486 part
of the UDA50 adapter set. Now I no longer get a 3 on the M7485's
LEDs but it properly goes up to the 4/5 blink. Even the port light
on my RA90 lights up so that it feels like it's going to come up
any minute. But it doesn't. The VAX console never shows any
sign of life, the RUN light goes off and the M7485's LEDs show a
constant 5 (no more blinking 4/5). Then the drive's port light
goes off too.
When I interrupt the console and UNJAM it says "HALTED AT 000007B7"
The interesting thing is that I can set the R3 register (that
indicates the device unit on the UDA50) to a different value (my
drive is set as unit 0) and indeed the drive's port light never
lights up, as it should. However, the machine hangs in the exact
same way and when I interrupt it, it comes up at the exact same
address 000007B7. Would that mean that we get stuck even before
the boot sector is loaded from the disk?
I have two straws of hope to hold on. One is that the basic
diagnostics tells me that KA780 module M8230 fails. So I can
replace that once I have a spare. The other hope is that my
UNIBUS isn't properly terminated.
I have what looks like a UNIBUS terminator card but whenever
I plug that in, the UDA50 acts strangely and effectively never
reacts to the host at all, just constant cycling pattern as
if nothing ever happened. Also, my level 2 diagnostics fails
when this terminator card in is. When I remove that terminator
I see at least the UDA50 and host communicating a little as
described above. And without terminator the diagnostics level
2 finishes flawlessly.
How essential is the UNIBUS terminator? Does the missing
terminator explain why the host hangs and silently stops
during boot? I never get a machine check or anything.
Or, am I just impatient??????? I do know from my other VAXen
(6400) that they turn on all fail lights and make the
drive's port LED go off during the first phase of the booting
activity. Could it be that the VAX 11/780 just needs several
minutes for this job? I don't think so...
Who knows what the address 7B7 in
Thanks,
-Gunther

Hi All !!
A good haul at the local University auction has netted me
a coupla Sun Ulta2's, a few vt420 monitors an IBM3151 terminal
and the neatest find in the last few months....
A russian pdp-11.
It appears to be an exact replica of a dec professional 350.
It has the same case as the decmate/ rainbow/professional series.
All the labels, everything, is in cyrillic, but it is an exact replica
of my 350, the only difference is that instead of the funky
dec dual RX50, it has two ordinary looking 51/4 floppies,
and the color is what my friend calls a soyuz silver or moscow gray,
as opposed to the dec beige/sand.
It has what appears to be a RD50/52 but it is all labeled in russian.
It even has the CTI bus cage with the cards for the drives.
On sliding the mainboard out, it is identical to my 350, except
for a few oddities, and all the chips are labeled in cyrillic!.
It dates from 1988 and seems to be in excellent condition, except for
the upper plastic cover is missing the front plate.
I was really tempted to fire it up, as it appears to have, an US style
110 power receptical. But second thoughts, made me cautious as
I'm not sure of its electrical requirements and would hate to toast the power
supply or boards as it is a bit different from the 350 in size and various
connectors.
If anybody has seen one of these or has info, I'd apreciate a little help!!
In the mean time I'll did up my russian-english dictionary and
maybe try to trans-literate the cyrillic characters.
Cheers

bit of cleanup, but it does work just fine. Available for pickup in the S.F.
Bay area. Otherwise you need to pay for the shipping.
First come, first serve. Let me know.
Thanks,
Bill
I've been working on trying to get a pair of TRS-80 systems transferred
>from Southern RI to sunny NorCal but I'm finding that the extent of the
collection makes it prohibitively expensive to pack and ship (5 boxes of
stuff from what I'm told).
Is there anyone in the RI area interested in rescuing a TRS-80 Model III
and a TRS-80 Model 1000SX (Early PC Clone)? There are peripherals (at
least one printer, for instance) and lots of docs and software for
these.
I'm just trying to back gracefully out of the deal without leaving the
donor hanging. I've belatedly realized that I can't justify the expense
of shipping these relatively common systems from coast to coast.
Please contact me if you've got an interest and I'll do what I can to
set you up.

Hi Nico,
Yes, they are 9 track reel to reels.

do you mean Microsoft Basic Professional development system version 7 and 7.1?
there's also Visual basic for dos Version 1.0 which came after QB 4.5
Hi, all:
Does someone on the list have documentation for the Remex "Director" paper
tape readers (model numbers RRS9000 or RRS9006)? I've read manuals for
other Remex models online, but not much of use for this one.
In particular I'm curious about what effect the "spool/loop" switch has
on operation, what kind of checking is done by the power-up self-check,
and if there's some good sensible way to test the stepper motor driving
the tape sprocket.
If I can get some more data, it may save at least _one_ paper tape reader
>from having a long and dusty servitude in a storage room. :)

Hi,
I received the following two-part email this week...
A free 9835...
...
I moved up to an HP 9835.
[It's in Canada]
...
Now the good news, I still have the 9835 in my basement. I think it's
still close to being
functional, it turns on without clouds of blue smoke but the monitor
appears to have given up so no way of seeing if it is really booting
up. I'm not sure about the tape drive?
If you could locate a monitor, maybe you could get a functioning 9835.
It's free to a good home
And, the project:
I have been looking everywhere for anyone who might have a functioning
9835/45 because I still have about 10 tapes with thousands of pages of
HP BASIC that I would love to off load to some form of modern media in
ASCII and translate into modern BASIC. If you could help me with this
problem I would even pay the shipping of the 9835 to you, if you are
interested?
Anyone interested, reply (offline) to me, and I'll pass the contact info
on to you.
thanks,
Stan

I would like to get an old single floppy DOS laptop machine
on my local network. Anyone know how to get DOS to work with
a PCMCIA card (uh too new?)
It would be great to finally have this machine boot up as an
emulated apple or PDP-8 or Atari or something.
One of the floppyies makes it into a disk drive for my TRS-80 model
100 laptop.

Hi Jos,
It was a pleasure to show you the Museum and the Kenbak :) I hope you had a
nice vacation in Nova Scotia.
I will eventually scan all the material and make them available for
everybody interested in the Kenbaks. It will most likely be published on
CD-Rom since it is a lot of material (especially the schematics).
It will take a bit time since I do all this in my spare time.
Greetings
Herbert
Hi all,
I finally have more news from the Kenbak-1 front. Earlier this year I posted
a message on this list that I discovered a Kenbak-1. Well as it turned out
the source I had the machine from had 7 (!) more Kenbak-1s. After long
negotiations we finally agreed on a price for the collection of 6 machines
and incredible paperwork. (The seller wanted to keep one machine) After some
more struggle to get the money together I finally purchased what I consider
the "find of my life". Here is what I could acquire:
- 6 Kenbak-1 computers
- the original schematics (a big folder!)
- original training films from 1974 and the early eighties.
- an original sales flyer from CTI, a company that tried to market the
Kenbak-1.
- programming manuals, flow charts etc.
I drove all from Nova Scotia, Canada to Charleston, South Carolina to pick
the lot up. (3000 miles)
More information about the computers, where they are from and most
importantly photos of the Kenbaks are on my website:
http://www.computermuseum.20m.com/kenbak.htm
I currently try to convert the original training films. I'm also in the
process of taking photos from the insides of all the machines. Those photos
will be online within the next days.
Four of the seven Computers have the original Kenbak-1 logo, the others the
CTI logo.
You will see that al of the computers have six holes drilled on the top
cover. It turned out that the Kenbak-1s had overheating problems and the
hole were the cure for that.
One of the Kenbaks is slightly modified and has toggle switches instead of
the push-button switches. This machine is the only one I have tested so far.
It works perfectly. All I can say is that the Kenbak-1 is fun to work with!
Greetings

Anyone have a manual for a Citizen's GSX-190 printer?
I'm trying to find out how many multi-copy pages it can support. I need a
dot matrix printer that supports AT LEAST five carbonless copies
(counting the original). Mac compatible is prefered, but I can deal with
Parallel.
I have an old Citizen GSX-190, and it supports underside paper feed,
which I have found is usually a good sign for a printer designed to use
multi-part forms... but I want to verify how many pages it is designed
for before I go thru the effort of trying to get it hooked up (only to
find that it looses grip on the pages just like my Imagewriters do, the
Imagewriter is only designed to handle 4 copies max)

What is too far away ?
I was able to seen the Nova Scotia Kenbak on a trip from
Switzerland....
Herbert was even kind enough to open in up for me. Thanks !

( And Nova Scotia was not too bad either !)
