Any idea what the version overlap (if any) is between RT and RS/6000? In other words, are there any versions that would boot on either machine? This is just curiosity for now.

Many thanks for the helpful comments from Pete, Tony and Adrian.
Lucky for me I discovered that the terminal pins unscrew.
ALL of the keyswitch terminal pins have be cleaned with a
mild abrasive (Brasso) and then washed in IPA. I had to
remove all of the switches to clean the rust from the
frame, but what the hell, they're back to original condition.
BTW I don't have any WD40 and would never ever use it on any
electrical or mechanical parts - never ever !
Also, as the leaf springs in the key switches are gold plated
I've left them 'as is' and not used any propriety "switch cleaners".
They should work for another 15 years :-)
Also, fixed the intermittent dry joint in the PSU and added the
composite video colour mod. Found the last one on the
Acorn FTP site http://acorn.riscos.com/documents/appnotes/
This was one of my better buys from Ebay. My only complaint
is the tatty case - I will have to think about "re-boxing" it.
Perhaps in a 1U 19in case, it will make the connectors a little
more accessible and support the weight of the Cumana dual
disk drives !
Thanks for the help

Joe,
After reading your three messages, it seems you also
see the disparity.
There is one point that the author of that page about
sniping did not seem to consider. If auctions did automatically
extend, but in each extension period, the minimum increment
doubled, it could autoextend, yet still come to an end fairly
quickly.
Because of the sniping issue, I feel that eBay can't really
be held as a true measure of the value of things. Only in auctions
that had a chance to "settle" at the highest price someone was
willing to pay for something, would it be valid measurement tool,
of that aspect only of an overall market system, also keeping in
mind the terms, i.e. untested, "as-is", tested, guaranteed, etc.
The on-line auctions run by the GSA use a proxy bidding
system, and also have an autoextend feature. Bear in mind
that their prices are not a true measure of actual value
either, because some of what they sell is broken damaged stuff,
and you don't know what is what until you've bought it. They
also don't entertain complaints.

Meanwhile, back at the ranch....
The IBM RT I was given last weekend turned out to be configured with:
Enhanced Advanced 032 processor, which is hardwired with 16MB of
RAM. No Advanced Floating-Point Accelerator, drat it all.
Extended Monochrome Display adapter (1024x768) w/6155 mono display
Ungerman-Bass Baseband [ethernet] adapter
Streaming Tape Drive Adapter - RT interface for 6157 1/4 tape drive
No tape drive or cable
1 5.25" DSHD floppy drive
3 E70 70MB ESDI hard disks - 2 dead as dirt.
1 SIIG 8-bit Serial/Parallel adapter, c.1998, which prevents booting
Keyboard
I was able to find archived images of AIX v2.2.1 (which, interestingly
enough, I may be able to use *legally*. IBM permits their AIX
instructors to run AIX on personal machines for private/non-commercial
machines. I'm NOT gonna call Mr. Wolden and ask....) The archive
includes VRM, BOS and Extended Utilities, all IBM's updates & patches,
the NFS add-ons, man pages (IBM *still* provides the man pages as a
separate product!), TCP/IP, and some GNU stuff. And the all-important
Diags disk set.
NOTE: If you ever have to work on an IBM workstation, as soon as
you get the case open, get a paper clip, solder pick, fountain pen, or
other not-very-sharp object, and gouge a couple of knuckles with it.
Bleeding directly onto the machine is not necessary, but every IBM I've
ever worked on required the ritual blood sacrifice before booting.
The machine booted to the Diags just fine, after I pulled the serial
adapter. There I discovered that the keyboard has several dead keys
(well, two, but the Escape key counts triple), that the RT wants
<Ctrl>+<Alt>+<Pause> to reboot, and that the display must be powered up
before the computer. Everything but the 2 dead E70 drives and the
keyboard checked out.
There are numerous refernces to the use of IDE drives in the RT
newsgroup. Although AIX actually will install in 70MB, it leaves little
room to play in. Plus, that one E70 alone was warming my house and
whining loudly enough to make my cats cry.
Final verdict: they're right, but I saw some glitches I haven't seen
documented.
You need a "dumb" ISA IDE/floppy controller. It must be set to
secondary IDE and primary floppy. Any serial/parallel/game ports will
probably have to be disabled. The RT will boot from a secondary IDE
controller, if you satisfy the drive specs. On mine, even aftetr
removing the ESDI controller, setting the IDE card to primary causes the
machine to freeze on boot.
Drive specs: A Seagate Medalist IDE drive. Period. Some posts suggest
that small Quantum or Conner drives will work, but not boot. The WD,
Quantum, and Maxtor drives I tried weren't detected at all. The Conner
340MB was detected and passed, but I haven't tried booting it. The
Seagate ST3250A Medalist is booting quite nicely as hd(1,0). I did try
an ST32122A 2G, and it installed OK and booted fine once. After that,
it drops into maintenance mode on boot, with unrecoverable errors.
Mount claims that the filesystem devices don't exist. I'm not convinced
that wasn't due to operator error during install.
Still to do:
Find vi. I haven't installed the Extended set yet. Please Gods don't
make me use ed.
Set up TCP/IP networking. Just got the TCP/IP set installed last
night, and configuration is waiting on vi. I hope.
I've been offered a copy of 4.4BSD/Romp for it, which I may try out.
I'd like to try AOS, but I can't find the full distribution, just the
tools, updates, and diagnostic utilities.
Find a mouse.
Suck it up, gird my loins, and try repairing the keyboard. I may try
using stty to remap the dead keys till I have a backup kbd.
Yee-Haw. I now have AIX v2.2.1, toys, tools & updates, on 5.25
floppy!

My UMatic experience is really limited to just Panasonic and Sony units
(dating from mid-late 70's thru my newest Sony is maybe 10 years old now).
But interestingly... I was wrong... I HAVE seen the "UHF" connector for
composite. I had completely forgotten about the old closed circuit video
system I pulled out when I started working at my current job.
They had 3 black and white security cameras that used that connector. I
know they were composite video, because I remember using an RCA adaptor,
and connecting one to a VCR's video line in shortly after pulling them
out of service.
So yeah... I have actually seen that setup, I had just forgotten about
it, as it might have been the only place I have seen that (but also, 90%
of my AV experience is from mid 80's to mid-late 90's, so most of what I
was exposed to is the "current standards" connectors). That's why I
disclaimed that I wasn't saying it didn't exist... just that I hadn't
seen it (I have also learned in A/V, if there is a connector out there,
odds are, someone, at sometime, used it in their setup)

Monitors and terminals are a necessity. Printers aren't. That doesn't mean that I won't have printers, but they need to be more impressive. I have a Genicom, for instance, which I've kept due to its unique ability to survive the direct impact of a locomotive.

thought it was a Multibus card but a closer look reveals that it's (1) too
tall, (2) too narrow, (3) The large connector at the bottom has 100
contacts instead of 86, (4) the narrow connector has 40 pins instead of 60
and it sticks down too far.
Any ideas?

The rectangular boxes are relays, look like mercury wetted contact relays.
The Bus is some sort of lab instrumentation and control. I am not sure what
it is called. It is familiar with me too. I have seen quite a few similar

When I was key swapping to get a complete Master keyboard using a scrap
machine I noticed the keyswitches were glued together and not clipped. I
wanted to just swap over the plungers but had to swap over the whole switch
instead.

Owen,
still interested in getting your PDP-11/34 to work? - I am just about to
reassemble mine after relocation.
RUN light off and display 000002 means the processor halted at memory
location 2, so it has probably executed a HALT instruction (opcode
000000) from location 0.
Try this: while holding the CNTRL button, press BOOT. This should launch
the program from your ROM. Depending on which type you have (look for
modules labeled M9301 or M9312 in slot 3 or 4, whatever is next to the
processor), your milage may vary here.
The console terminal should print four numbers in octal, followed by an
"@" or a "$" as a prompt in a new line ("Dave, my mind is going...").
Depending on the ROM, you may need to enter either 773000G (standard
start address and GO command, pressing the return key is _not_ required
here) or a two-letter device code to boot. The bootstrap module may also
be wired to boot from a predetermined device without asking.
BTW: The DL11-W has 20mA drivers as well as RS-232. (Note the "1488" and
"1489" chips being present as well as a number of transistors and other
discrete components.) Which set is used depends on the cable: the plug
will have some wire connections to code it for either 20mA current loop
or RS-232 / V.24. If you have the original cable with the usual DB-25
connector, it should be OK: current loop used a completely different
6-pin "Mate-n-Lock" connector.
For the settings at the terminal, I don't know your particular type, but
with most DEC lines you should be best prepared if you use XON/XOFF
handshake (for "Main Rcv Hndsk" / "Main Xmt Hdsk"). Since at PDP-11
times, the 8th bit was commonly used as a parity bit, set your terminal
to ignore this. Otherwise, you may get garbage characters instead of
about every second readable character. We may get this straight later,
when we know what operating system you have.
A RS-232 break signal can sometimes cause a PDP-11 to HALT (depending on
settings on the DL11-W board), so you may want to avoid this... (perhaps
by choosing an appropriate setting for the "Disconnect" option for now?)
So much from memory. If you need more details, let me know, and I'll dig
into the docs.
Good luck,
Andreas

Y'all,
I am sure you will all be happy to know the following...
Dell fields Super Bowl deal
Dell Computer announced that it has signed on to be the National
Football League's official computer systems provider for the upcoming
Super Bowl XXXVI. Dell also signed a deal to be the NFL's hardware
supplier for the remainder of 2002.
As part of the Super Bowl agreement, the company will provide on-site
service and support for computer systems used in Super Bowl
operations, which will include some 200 Dell desktops imported to New
Orleans from league headquarters. And under the new Dell-NFL hardware
agreement, the league will purchase 120 or more PowerEdge 2500 servers
and a storage area network. Dell says it has had a sales relationship
with the NFL since 1998. --John G. Spooner, ZDNet News

Hello from mild and almost snowless Montreal...
A recent find for $5.
NCD 88k xterm, no keyboard, no ram, no monitor...
Very little help on the web about this.
I wanna try this out, I am not sure why...
Anyways who knows the ram simms specs and where they go in this thing (unit
came with no ram) I managed to get some "normal reaction" by putting a 1M
simm in the inner most simm socket and 2 X 4M simms in the outter most
sockets. I am saying "normal reaction" cause I have still not found a
monitor that will produce stable output on this thing. I do see somekinda
"unsync-ed" POST and looks like text appearing and scrolling on screen every
approx 5 secs, imagine the term is looking to boot from somewhere...
Who can tell me more about the video output specs? Looks like mono and my
pinout seems ok 15,16,17 R,G,B and 26 TTL Vsync and 18 TTL Hsync from
looking at it with a scope...
Any help appreciated...

Pat,
Unless you have a need to control a bunch of 3270-emulating terminals, a
6544 isn't a terrible useful thing to have. It's basically a non-IBM version
of a 3174, etc., which is a unit used to hook up many terminals to your
3270-protocol host computer, be it mainframe or minicomputer. I don't know
what terminals the thing is meant for, since it beats me if AT&T's terminals
support 3270, but they probably do, though I'd imagine it doesn't use coax..
Which, if that is true, might limit you to using AT&T terminals with it,
which is kinda crappy.. Hope that helps some

Hi everyone!
I went to the University of Michigan Property Dispotition warehouse
today, and I've got a couple of questions and other related things
to say.
1. To the couple of people who asked me about the NeXTDimension Cube
that was there last month, my apologies, but someone else got to it
before I could.
2. I saw a DEC pedestal cabinet there that looked exactly like a VAX
4000 series machine, but it was just labeled "R 4000". I'm assuming
this was some sort of VAX, and there seems to have been a thread on
the NetBSD/vax mailing list about it a while back, but since their
mailing list archive server seems to be down at the moment, can anyone
tell me more about this machine? I'm a bit curious as to what it
is.
3. There was an interesting looking Evans & Sutherland computer there
labeled as an ES-3. I popped the front cover off of it and it looked
relatively sophisticated, but I didn't actually pull any boards and
get a good look at them since they don't like people doing that sort
of thing there at the warehouse. I read somewhere that this box runs
UNIX and had some pretty nice graphics capabilities for its time. Does
anyone know much about these (e.g. architechture, history, OS
specifics, etc)? Does anyone know how they stacked up to SGIs of the
era and similar competing machines? The thing's kind of heavy and
transportation to and from the warehouse is pretty evil for me, but
if its a really nifty machine, I'd like to save it (I've certainly
never seen one before). Unfortunately there didn't seem to be any
monitor, keyboard, or mouse included with it. Does anyone know any
specifics about these either?
Hmmm... other oddiments there that were kind of interesting included
a dual 8" Data General floppy disk drive, an old SGI POWER SERIES
Twin Tower machine, and probably some other stuff that I'm forgetting.
Just thought I'd mention them in case someone lived in the area and
was interested in taking a look.
Kind regards,
Sean Caron

IIRC it's a DSSI Disk cabinet (might also have Q-Bus slots for Q-Bus
expansion). Can't really get to mine to verify what the nameplate says
(it's being used as a PDP-8/e stand and is crammed between a wall and and
the Neo Geo cabinet).

I've recently received a small pile of IBM 3151 terminals. All seem
functional. I also have a pile of IBM keyboards, some of which look
like they may fit the terminals.
The two keyboard types of interest (IE the ones with modular plugs)
are:
A model "1397952" -- this one has an 8-wire modular plug. When plugged
into one of the terminals, it will say something on the order of
"PROBLEM IN KEYBOARD"
A keyboard that's not clearly marked at all, but the longest
identifier-looking number on the tag is 122RK33S(or 5)-30S(or 5)E-J.
This has (I think) a 6-wire modular plug. It has a panel of dip
switches near where the cord connects. When plugged in this one
reports the (more interesting) error of "PROBLEM IN VIDEO ELEMENT OR
KEYBOARD" (My guess it it's in the keyboard...)
Both keyboards have 24 "function" keys, and a panel of odd keys to the
left of the alpha section.
So does anyone know what these particular keyboards actually go with?
Can I maybe change the switch settings in the latter keyboard, and get
it to work with these terminals? Does anyone know what the switches
even do?
Why don't the terminals report odd numeric errors? "PROBLEM IN KEYBOARD"
is almost understandable ;)

Hello. I have one IBM 3101 ascii terminal ready to be used
connected with one serial cable to one Linux system that
I have by the serial port 2. The inittab has uncommented the
line referred to the ttyS1, and appears to be correct because
one "ps -ef" shows the "/sbin/agetty ttyS1" line with the "[login]"
comment.
The problem is that the IBM 3101 don't establish communication
with the Linux system. The 3101 show one "Line Check 2" message
that talk about the comm.line, I suppose. The cable used is one
normal serial cable.
The 3101 has some dip switches in the upper of the keyboard.
If they are taked, the Line Check 2 message dissapears and
the screen is filled with "?" signs continuously. It's clear that
some options can be configured with this method.
Somebody has some more deep info about this terminal ?
Must I use one special serial cable ?
Thanks and Greetings

I know I'm going to open up a can of worms on this post, but my curiosity
is killing me....
Now that I have OpenVMS 6.1 running on my VAX 4000, I'm curious about the
status of the various "FreeVMS" projects that are in progress (or so it
would seem....).
Are any of these projects really in active development? Which projects have
the greatest potential for operation? I checked several sites related to
"FreeVMS", which actually seems to be a common name for several different
projects with different goals.
I'd love to "cut my teeth" with kernel development after working with Linux
for several years. I personally think it would be neat to have an accurate
version of FreeVMS that would work on VAX, AXP, and i386 (gulp!). When I
say accurate, I mean that FreeVMS would respond the same as VMS would for
the various commands and peripherals.
Some of you probably think it would be silly to take an i386 version of
FreeVMS and port it "back" to VAX and AXP, but it would be a neat way to
use FreeVMS, especially if the OpenVMS hobbyist program (or OpenVMS) were
to go away.
Nuts? Probably. Neat? Yes!
Here are links to the various FreeVMS projects I have visited:

Whether you need to unsolder all the keyswitches depends on the keyboard --
there were 4 types, but only one -- fortunately the least common type --
needs much work. The best, and original, was the type using Futaba
keyswitches, which have a white body. These are easy to remove, one at a
time (desolder the connections, then release the clips which hold the
keyswitch in the frame). I've seen a couple of pictures on the web showing
the different types but I can't seem to find one right now :-(
The normal way to fix faulty ones was to replace them. You can still
sometimes find switches available from people who've dismantled machines.
If not, I'd try removing the faulty keyswitches and cleaning them by
swishing them in a small bowl of iso-propyl alcohol, or squirting IPA
followed by switch cleaner through them. Finish with a good-quality
low-residue switch cleaner. These are generally based on IPA with small
amounts of very light oil (not usually silicone, as it creeps too much and
gets into everything). Do not use anything like WD40!

I think it might have had more to do with what kind of single was being
sent. (at least in the video industry)
My old UMatic decks from the 70s have either "UHF" connectors (PL-259),
or F connectors (depending on age) for all the modulated signals
(connects to a TV shows on either channel 3/4 or 6), but all the ones
that have composite signals (non-modulated, needs a "line in") have
either BNC or RCA (depending on quality, doesn't seem to have bearing on
age... higher quality decks have the BNC for video, RCA for audio, and
lower quality have the RCA for video and audio).
I don't think I have ever seen a "UHF" (PL-259) or F connector on a non
modulated composite signal (not saying they don't exist, just I have
never seen them), same with I don't think I have ever seen a BNC or RCA
on a modulated signal.

All of this is off-topic, but I've got three different types of Iomega
ZIP drive "wall warts" here (all voltages unloaded, measured from
my Fluke 8020A):
57DR-5-1500(A) outputs 5.21 volts DC
48DR-5-1000 outputs 5.11 VDC
91-56403 outputs 5.15 VDC
Much closer to spec than most wall warts.

Great, thanks for the advice Pete. Did a quick search with Goolge and found
a few tips on BBC keyboard repair. It seems I have a type I keyboard with
Futaba keyswitches fitted. They come out of the frame one at a time.
After a bit of fiddling I discovered that the keyswitch body is held together
by a small plastic clip and two screws. The terminal pins are the screws
and can be removed by gently rotating with a pair of pliers.
Terminal pins are silver plated and show signs of tarnishing on the faulty
keyswitches. The contact leaf springs appear to be OK. A mild abrasive
and some IPA should do the trick :-)
Just wish I'd kept that Cherry keyboard form years ago with the Hall effect
switches.

Hello, all:
I am finally getting around to building the P112 Z180-based SBC from
Dave Brooks (I got one of his last unpopulated boards). It has two 100-pin
QFP chips (the Z180 and an SMC Super I/O chip), so, I bought the blade-like
SMD soldering iron tip for my iron.
So, here's the stupid question...how do I solder these things? Do I
hold the iron parallel or perpendicular to the package leads? The board is
pre-tinned, but I should I also tin the QFP leads?
Any help appreciated.

They go into pre-drilled cylindrical studs that extend from the back of the
case (the side that doesn't plug into the wall) toward the front. There
were matching
cylindrical recess barrels from the front that extended toward the back and
had holes in their circular bottoms large enough for the screw threads to
pass through. Those barrels were what melted.

Self-stripping :-) which is what I'll therefore replace them with.

I think that's it. Why did I see a small voltage when I tested it *after*
the fuse blew? The - side doesn't connect to *anything* - I'd think it'd
float right up to the voltage of the positive side (charging through my VOM
meter, if no other way). Or is there some effective resistance through the
electrolytic?

Hm. Maybe. I actually have a small fuseholder (one of the few parts I have
in my box). I'll see whether I can make it fit. It would mount in among
caps and diodes with not much room to spare on a small circuit board,
though, so I may be stuck with a pigtail version.

Heh. That was my first guess too -- but I've never seen this particular thing used on a composite video signal before. (Well, maybe the L+sync used on b&w monitors...)
My assumption will be (until I can check it out) that these are simply split off of the original apple RCA plug on the mainboard, and carry the same signal. (I hope this is the case, since it would be a simple matter of fabricating an adaptor (for which I may have the parts...).

Does anybody out there have the docs available for the TSU05 controller
board used in PDP-11s or VAXes with UNIBUS to connect to the DEC variant
of the Cipher F880?
The board is M7455, and I am looking for the meanings of the DIP
switches.
There must be CSR address and interrupt vector, each made up by several
individual switches, but in addition to that, an "extended features"
switch and one for "buffering".
And, no, I am certain that I did not confuse this with the TSV05 (M7196)
for Qbus.
Thanks in advance!

Owen,
still interested in getting your PDP-11/34 to work? - I am just about to
reassemble mine after relocation.
RUN light off and display 000002 means the processor halted at memory
location 2, so it has probably executed a HALT instruction (opcode
000000) from location 0.
Try this: enter 773000, load this address, and then press START. Since
773000 is the standard start address for a bootstrap ROM, this should
get you a response on the console terminal attached to the DL-11W.
(Don't remember which, but I think it should ask for a two-letter device
code to boot.)
BTW: The DL11-W has a 20mA interface as well as RS-232. (Note the "1488"
and "1489" chips being present as well as a number of transistors and
other discrete components.) Which on is used depends on the cable: the
plug will have some wire connections to code it for either 20mA current
loop or RS-232 / V.24. If you have an original cable with the usual
DB-25 connector, it should be OK: current loop used a completely
different 6-pin connector.
For the settings at the terminal, I don't know this particular type, but
with most DEC lines you should be best prepared if you use XON/XOFF
handshake ("Main Rcv Hndsk" / "Main Xmt Hdsk"). Since at PDP-11 times,
the 8th bit was commonly used as a parity bit, set your terminal to
ignore this. Otherwise, you may get garbage characters instead of about
every second readable character.
A RS-232 break signal (certain voltage level applied for a certain time,
not a sequence of bits!) can sometimes cause a PDP-11 to HALT (depending
on settings on the interface board), so you may want to avoid this...
(perhaps by choosing an appropriate setting for the "Disconnect" option
for now?)
So much from memory. If you need more details, let me know, and I'll dig
into the docs.
Good luck,
Andreas

Am I correct in thinking that all the keys need to unsoldered from the PCB,

Although I have (I believe) all of the manuals for the Zenith Z-100 (not
Z-100 pc), I cannot find any reference to the serial ports on this box.
What are the addresses of the DTE and DCE ports? I'd like to write some
assembly code to access these devices (under CP/M-86) but want to control
them at the hardware level instead of making BDOS calls.
Any help out there?

Demystify? I don't know, I expect my mother is as mystified about her
spiffy new 2001 iMac as she is about her 1988 Mac Plus. She just
expects me to understand, and hopes she can figure it out before
she has to resort to calling me.
On the other hand, it does simplify computers!
2001's iMac came with a sheet of setup instructions. Six numbered
pictures, no words, and step 6 is pressing the power switch. It's
real simple, just connect keyboard to computer, mouse to keyboard,
phone or ethernet to computer, computer to power, and then press the
power switch. No need to fuss with monitor or speakers, they're
built-in.
What was real fun about this upgrade was getting the files from the
Mac Plus to the iMac. The Mac Plus can write 800KB stiffies, SCSI,
and serial; and the iMac can read CD-ROM, USB, Ethernet, modem, and
Firewire. Note what they have in common: nothing.
I did a dry run using an iBook and my old Mac Plus. First I got a
Belkin USB-to-SCSI doohickey and installed that on the iBook. Then I
connected the Mac Plus' hard disk to the SCSI doohickey and booted
MacOS 9.2. It asked me whether I wanted to initialize the
unrecognized volume, and I told it no. So much for that idea, and a
good thing it wasn't listening for spoken commands as I'd probably
have turned its ears blue.
The next try was with Basilisk II running on a Windows Me Harder
notebook, emulating a Quadra 650 and running System 7.5.3. This
worked better: I was able to connect the Plus' hard disk via an
Adaptec SlimSCSI PCMCIA interface and mount it and copy the files
over. Then I was able to use Appletalk to share the volume over the
notebook's Ethernet interface and mount it from the iBook.
So the WinMe notebook went back east with me. There I found that
Mom's Mac Plus' hard disk is a Jasmine, and there's something about it
that doesn't work with Basilisk II running System 7.5.3. If it's on
the SCSI bus, the simulated Mac hangs when it tries to mount the disk.
After three days of fussing with this I punted, used Stuffit on Mom's
Mac Plus to make archives of all her stuff (all 8MB of it!) and Mac
Kermit to transfer the archives over serial cabling to the simulated
Mac. That took a couple of multiple-hour sessions so let's say a day.
Then I unpacked the archives on the simulated Mac and did the
Appletalk share so the iMac could copy the files over.
And y'know what? AppleWorks 6.1.2 knows how to read ClarisWorks 1.0
files. One of my co-workers was the QA lead for ClarisWorks 1.0, and
he is very happy to know not only that a little old lady in Maryland
was using it for most of the last decade, but that her bits are safe.
I'm very happy too.

Hello all,
I had promised to post an update when the fate of the ZS-1 systems had
been decided. Here it is.
After negotiating with my company (Astronautics) for the release of the
four remaining complete systems that sit at our Technology Center in
Madison Wisconsin, we were able to secure one of the machines for the
Rhode Island Computer Museum. The company is not the least bit
interested in preserving the other three. They are destined to be
scrapped. We tried. :(
Merle Peirce will be in Madison this saturday, January 26th, to pick up
the machine and _lots_ of spares for RICM. We will also be moving the
DEC VAX 11/780 systems and other equipment at that time.
If you are in the area and would like to lend a hand, please let me
know. I am sure that we will be able to find a few souvenirs that will
make it worthwhile. Merle plans to be at Astronautics around 9am
saturday. Thankfully, the weather forecast calls for unseasonably warm
temperatures this weekend (lower 40's).
Again, please let me know if you plan to come.
Thanks,
Jon

P.S. To anyone who I may have failed to reply to personally, I
apologize. The flood of e-mail that was generated by my posts about the
ZS systems and the 11/780s was overwhelming. Between this, preparing to
move our facility, and the possibility of pending unemployment, I have
been having trouble keeping all of the balls in the air.

They look like a Torx screw head turned inside out. Imagine something
between a pan head and a round head (ie slightly domed) with six small
notches in the edge. The sides are sloping/curved and they're usually
hardened, and the edges of the notches are slightly rounded off so you
can't get a grip with pliers. There's a picture at

All,
Potentially useful info for the list:
1) Stylewriter power supply uses zero-screws (or whatever you call them).
2) Stylewriter PS has a seperate fuse in the - leg of the output, and it's easy
to desolder.
The long version:
Sat down with murder in my eye to work on the power supply.

A perfect description of the three fasteners holding the case
together - as I realized once I had them out in the light of day.
Unfortunately I *got* them out in the light of day by trying to pop them
loose after heating with a soldering iron. Instead of melting the studs the
threads were threaded into, I melted the barrels of the recesses the screw
heads were in. Things Got Smelly, the case creaked apart, and the recess
barrels were left with the studs, screws still firmly in place. However, at
that point, I was able to grab the severed barrels, squeeze with pliers
until the walls of the barrel gripped the zero-screw head, and twist out
the zero-screw.
Anybody need 3 slightly used zero-screws? *I* sure as heck don't!
To put back together, I plan to find longer pan-head screws with
similar diameter and thread pitch, put around the studs plastic soda straws
long enough to reach up to the other side of the case, then put the
pan-head screws (with washers as needed) through the holes that originally
formed the tops of the recessions and through the straws into the studs.
(The soda straws are to electrically isolate the screws from whatever
voltages are flying around inside, because the recess barrels ain't gonna
do it, now being in pieces in my trash can (with extreme prejudice).)
Inside, there's a big transformer. One side has 2 leads wired to
the blades that go into the wall. The other side has 3 leads going to a
circuit board. The leads on either end go through diodes to the "+" output.
The lead in the center (marked "C.T" - let me guess - center tap?) goes
through a cylindrical glass fuse to the "-" output. There's a big capacitor
(electrolytic? Black cylinder) between "+" and "-" and a few small
(ceramic?) disk capacators scattered around.
The fuse had shuffled off its mortal coil. I mean, even *before* I
desoldered it. Which, BTW and of course, I think I did without damaging
anything.
This thing is so simple even I can almost understand it. Now I need
a 3.7 (? something like that) Amp fuse with pigtails, and a couple screws,
and who knows, maybe I'll be back in power. Definitely going to be a
web-shopping day.
Comments, 'attaboys, "enough-already-with-the-d*mn-printer"'s,
etc., all welcome.

Ok guys, I have to admit first off that I read the tags wrong on that Bell & Howell. It is -- as someone suggested -- an Apple II Plus.
Also, it doesn't have the D-shaped cut-outs after all, but rather it has vertical slits with somewhat d-shaped metal inserts in them. (Ok so I didn't look too well.. :)
I've cleaned it up, and it looks in good condition, with two exceptions:
There is a pin broken off of the power cord :/ -- I'm going to replace it.
The monitor connectors are two ethernet-looking BNC plugs (WTF!?) Can anyone tell me what's going on with these?

This may be a bit off topic, but Yahoo is having a Free Listing Day on
January 24th thus reducing their already reasonable rates :). They do
have a Vintage classification and I expect to have some "stuff" there.
Yahoo has the facilities in place to handle a large number of auctions,
and with ebay continuing its direction towards retail, collectables need
a site that *wants* them.
The Xerox 4050 is a printer controller, but appears to be some sort of
mini-computer with a Xerox logo on it; it has a floppy drive and
possibly internal hard drive. If anyone knows anything else about
these, info posted to this list would be appreciated. The thing is
waiting for pickup by a scrapper, whose truck is currently being
repaired. If you get here first, you can have it. It's about the
size and weight of a chest freezer.
Also available is an IBM PS/2 Model 80-386 micro-channel tower
machine. Includes a micro-channel token-ring network card.
Both of these items were pulled from use in the last couple of months
and should be in good working order. They are available
_for_local_pickup_only_ in Lincoln, Nebraska. Drop me a note quick if
you want either of them before they go to the big bit-bucket in the

First, its Hackettstown, not Hackensack (at least that is where he told
ME he was... if it was Hackensack, I would have picked it up the night he
emailed me, being that Hackensack is 15 minutes from me... Hackettstown
is 60 minutes)
Second: I already told Paul I would be happy to pick it up. Then he
offered to drop it off at my place when he went to CT on Friday. I told
him that would be fine, but not to make a special trip (I can't figure a
way to get to me that is a route to CT without taking a good 30 minute
detour).
I guess I will re-email him, and clairfy that I am happy to drive to him
to pick it up.

Hi everybody,
I have three more Apple questions
Given that I'm going to be repairing that Apple II Plus soon, I find myself wondering what is the maximum amount of ram that the machine can address?
I also wonder whether it would be remotely possible to "upgrade" it with the old IIGS memory board that I swapped out of my GS a while back ;) (Probably no such luck there...)
Last, but not least, what are some recommended boards/peripherals for the Apple II Plus? What about the IIe? (Yep, got one of those too -- I'm sure this one really _is_ a IIe, and I'd be especially interested in knowing about the IIGS upgrade) What about the IIGS?

I have a couple of JVC monitors with BNC composite video connectors.
These are the monitors salvaged from a video editing suite... I actually
saw BNC used for composite video on a fairly regular basis in the TV
studios (I think I saw that more often then seeing RCA connectors)

You can buy a BNC to RCA adaptor from places like Radio Shack (or even a
BNC to RCA cable... although I am not sure Rat Shack stocks those
anymore... might be special order). Or, like you say, it is fairly
trivial to build a custom BNC to RCA cable.

>(When somebody trips over the cord, it should be strong

I always loved this logic. Lets build the cable really strong, so that
when someone trips on it... we save the $15 cable, but yank the $5000
computer onto the floor breaking it instead.
Although, I also understand the flip side... it isn't that the cable is
designed to withstand abuse, so much as designed to not fall out easily
during standard use (thus rational why all the electric cords for my fire
trucks use twist lock... even if it means it will knock over a $3000
light tower rather than unplug itself... the last thing you need at an
emergency scene is cords randomly unplugging themselves... and the last
thing a school tech person wants to deal with is 100 calls a week because
the RCA plug fell out again, and the untrained teachers don't know enough
to plug it back in... and things like BNC are used on pro level AV
equipment for the same reason, so cables aren't always falling out when
something is shifted around)
-chris
<http://www.mythtech.net>
..... there was a connector for the overhead video monitors. It was
an unusual connector, with a hollow cylindrical plug a few inches
long,
with a pin in the center.
That sounds like a MUSA connector, common in broadcasting but
not in domestic equipment.

It took forever because most of the SMP code is machine-independent.
Since most of the groundwork is now done, the folks working on
different architectures only have the machine-specific stuff to do.
VAX followed Alpha by a matter of a couple of weeks at most, for

48K on the motherboard, plus 16K on a standard RAM card (eg Language Card)
though I recall some that had 64K (not directly addressable, of course).

No.

this one really _is_ a IIe, and I'd be especially interested in knowing
about the IIGS upgrade) What about the IIGS?
I'd suggest language card, parallel printer card -- preferably one of the
better ones such as a Grappler card, serial card, 80-column card, second
Disk ][ card and two more drives if you want to run UCSD, hard drive
controller, ...
The //e takes the same cards, except that it already has 64K RAM and has no
need of a language card; it also has provision for a special 80-column card
in Slot 3, set back from the rest of the slots.

'Cos they're usually hardened and a dental burr will make little or no
impression on it. A cutting disk works, though, when there's room to get
at the screw head. It's easier to buy the right tool bit, though.
And they're usually so tight that epoxy will give way before you turn it.

Well...maybe. The SMP support in NetBSD is still pretty new, and still
lives in an "experimental" CVS branch. While the latest snapshot kernel
seems pretty reliable (./build.sh -j 2 works at least twice in a row :-),
it's probably not a good thing for production use just yet. YMMV.
Other than that, NetBSD is awfully useful.

I've found what I _think_ is the proper cable for this machine. These bits of info were buried somewhere in the HP web site. I unfortunately don't have the attributions (you can find them right now with a google search), but the general idea is:
-------------------
The HP part number for the cable is A1703-63003 and the price is $43 US dollars.
This info was found at
http://outfield.external.hp.com/cgi-bin/spi/main.pl
which is the home page for HP partsurfer, an application that allows toy to
identify and order parts for many HP machines.
--------------------
Pinout for standard console _cable_ (A1703-63003) is:
DIN CONNECTOR
FRONT VIEW
DIN 25pin
2__1 3.____.2
4____3
6||5 4.____.3
^
| 1.____.7
KEY
---------------------
These were both posted in reply to a question about a different machine -- "F" class I think -- but I have checked HP's "partsurfer" site, and the cable is, indeed, used on the "G" class as well.
I have contacted two resellers to see whether I can get it at a reasonable (read: not $46) price. Otherwise I will try to build it.
