My VAX 6000 is no longer here, so I have to go on memory. Pretty much all
there is in a standard 6000 is a row of PSUs at the top, a row with the
VAXBI and XMI busses and - right at the bottom - a converter/coditioner
that takes the incoming power feed and presents it to the rest of the box.
There is a large gap with plenty of air in it. About the only thing you could
use it for was a late-breaking internal storage addon. Every 6000 I've
seen had external storage (mostly via CI, since that's what big customers
were expected to do).
Internally it cannot have been much wider that 19" so I would guess that the
rack-mount version would be about the same but without the large wad
of air :-)

OK, I finally dug out my DEC systems & options catalogs, and found
a couple of references to the rack-mount 6000 in the 1990 and 1991
catalogs. These were originally sold as two 19" rack-mountable enclosures,
one containing the XMI cardcage, and the other containing a BI cardcage.
Both enclosures appear very similar, with the main difference being that
the XMI enclosure has a very small front panel on it. The BI enclosure
seems
to have a cutout on the front panel for a TK70 tape drive and _no_ front
panel. The earlier catalogs treat the 2 cardcages as 1 complete system,
while the later catalogs refer to the 19" rack BI enclosure as an "option".
Not being greatly familiar with the 6000, am I correct in assuming that
if you don't have the BI "option" you have not I/O capability whatsoever?
(except for possibly ethernet? how about SCSI?)

My first was either an Apple II+, or an IBM 5110. Both of which I still
have (I don't know if the II+ is the exact same unit as we had many of
them and some have been tossed).
My only issue is, which was it. When did the 5110 come out? I know the
Apple II+ was bought by my brother in 1978 (I had always remembered 1977,
but IIRC, the II Plus wasn't released until 78, and I'm sure it was a
Plus, not a regular II).
So if the 5110 was earlier than 78, I'd have to say it was the first
computer I saw and used.

They won't be willing to trade... but www.18004memory.com (Coast to Coast
Memory) sells these. I just bought two 64 MB ones (these exact ones) for
$23 each.
I can't say for sure if they are new, or used (they don't differentiate
on their site), but I do know that they test everything right before it
is packaged for shipping, so it worked when it left their store. They
also stand behind their chips, and will trade out anything that arrives
non-functional (or if you bought the wrong chip).

As I posted on 5/30, Alltronics has an adaptor that looks like what I had
for my O1 (which I no longer have). The link is
http://www.alltronics.com/computer_miscellaneous.htm and the catalog number
is #92C024. they are only $4.95, so you won't be out much if they are not
the right one. The description also fits: "Requires +12V (or +5V) and video,
vertical drive, horizontal drive signals. Produces RS-170 type composite
video output. Fully assembled with 74125 sync regenerator, 3 terminal
regulator, 2N2222 transistor. Only 2" square."

Yep, I just noticed one on ebay a little bit ago... I'm seriously
thinking about it... Are these equivalent to the full-blown 6000
systems that I've seen show up in the past? What are you giving
up by going with the rack-mount version? Also, anyone have
a guess as to how heavy these are? (UPS shipable?)

I watch a lot of Japanese Anime, and trust me, there is a lot of computer
generated work in there. While I've not seen much computer generated 3D
animation, there is definitly a lot of 2D that is computer generated.
On the 3D note, I was rather disappointed when I got the "Lensman" movie on
Laserdisc a few months ago. I'd seen it back in '93, and had forgotten that
it had a bunch of 3D animation mixed in with the traditional 2D. Simply
put, 3D animation, doesn't always age that well!

Yes, they are compatable/interchangable. I've ended up with a LK201
attached to the VT420 on my PDP-11/73 somehow, but the rest of the VT420's
I'm using have LK401's. I prefer the LK401's as they 'feel' better to me.
I think the keys are slightly different in shape/angle. I just wish they
had the flap that at least some LK201's have to put the piece of cardboard
that shows what the function keys are mapped to.

Why would one have a CP/M-85. There are only a couple of instructions
that are different than a 8080.
Well written CP/M code shouldn't care what machine it was on, only
the processor. Most general purpose CP/M-86 code should run on
a Z100 under CP/M-86. What am I missing??

I wonder if this is done on purpose. I had a EC-1 ( HeathKit analog
computer ) shipped by UPS. They wanted me to pick it up at the
depo so I did. When the guy brought it out, he says, "Gee, this
is a heavy one!" as he dropped it on the counter ( about 1.5 foot drop ).
I replied, carefully, not to let my anger show too much, " Yes,
it is a rare old piece of vacuum tube gear". He had a funny expression
on his face so I'm sure he understood how I felt. The fellow that
packed it had no padding at all. Remarkably, the tubes were all
OK but the inside chassis had bent a little, breaking some wires.
I debated writing a complaint but decided it might cause issues
with future deliveries.
I've had some bad luck with FedEx as well so I don't think either
does as good as they could. Partly, I think it is because the
people handling things don't care about the quality of their
work. It makes little difference if they do a good or bad job.
They get paid the same.

2 -- Although I have a lot of MS-DOS software for the Z100, I have no
intention of polluting yet another machine with MS products.
To the group: as the proud owner of two really pristine Z100s (one with
hard drive), I am amazed at the paucity of CP/M-86 software available for
this system. Most of the CP/M-86 stuff on the 'net is of the "CP/M-86 for
the IBM PC" flavor.
And *forget* about CP/M-85! It seems as if nobody ever used the 8085 MPU
in the Z100 . . .
Anybody care to 'splain me why this is? Am I the only person on the planet
who has/had any interest in running CP/M on the Z100?????? To me, running
MS-DOS on a Z100 turns it into just another kinda-PC-clone.

Actually the easiest way to build a 386-based terminal is with MSDOS
(or DRDOS) and kermit. Kermit supports most serial cards and even some
ethernet cards (so you can telnet over TCP/IP). There is even
DOS-based software for mouse support (so you can cut & paste text).
Kermit or DOS can take care of most input and output conversions so
you can talk to almost any system that support telnet or async serial.
BTW since most IDE disk have a spin down feature, you can spin down the disk
just after you load kermit, so you don't even have to listen to the hard
disk. Many systems of that era didn't have PSU fans, so spinning down
the disk made the system totally quiet.

And don't forget to have an ethernet card, and either a copy of PCTCP, or
anotherbootable OS on the system that has a TCP stack. One of these days
I'm going to build such a system. I've managed to collect all the parts,
and even a nice small PC, I just haven't found the time (or really a place

Hi there,
I have a two Epson HX20's (which we use in our reasearch lab - yes still
- to control some
equipment) one of which has sufferred a failure of the power supply on
the main CPU
board (details below) and I need to get hold of a schematic if one
exists. I beleive that Epson produced
a repair guide - does any one know where I might be able to source this
information.
I have had a plough through the archives to this list and there are some
very helpful people out there
and maybe if anyone has some experience with this machine and can give
me pointers - the following
might help ...
The batteries and external adaptor are good (new) charging correctly and
delivering 4.8 V.
However, the power switch has no effect (no LCD, no beeping)
The main power rails seem to be off - there is 4.8 v at one test point
0 at another an 2.8v scattered
around the board. There seems to be no 17 V which I beleive is needed
for the LCD.
The previous owner reported a burning smell so component failure is
suspected, but no obvious signs
on the transistors.
A previous writor in the archive (Tony Duell) suggests that a volatge
should be present on the collector of Q8,
this is absent.
Thanks in advance

Hi,
I have here a half working Teletype ASR35. I am missing some parts, namely
the plastic hood, manuals and some lightbulbs. Also the ASR35 isn't
working properly, I am missing half of the keyboard sorta speak, you can
type uptil the letter H or so and then if you continue it starts with the A
again.
So any help with that is also welcome.
Thanks!!
Stefan.
Hi Joe:
I subscribed and posted to cctech, but found your response in the cctalk
archive. This list is new to me -- do you think I should I subscribe to
cctalk instead of cctech?
>>>I have three or four 9915s and a keyboard... I don't know what the
difference is between an A and a B model... I did make a schematic of my
keyboard but I haven't seen it in a while...
>>>
As I understand it, the 9915A is compatible with the HP-85 (aka HP-85A),
while the 9915B is an 85B. IIRC, the 85B has built-in mass-storage and i/o
roms, and more ramdisk memory than the 85A.
I'd sure appreciate any keyboard info you may run across -- I could program
a little pic to convert a serial keyboard. If this keyboard is used with
other HP machines, other folks might find an adapter handy too.
>>>You need to use the HP composite monitors. IIRC the PN is 82912 and
82913. These are used on the HP 86 and commonly used on the 9000 220 (aka
9920) and are pretty common.
>>>
>>>There were software developement kits available that let you write
programs in assembler and burn them into EPROMs that plugged into a HP-85
type plug-in cartridges (called a Hybrid ROM or something like that) or
directly into the 9915. The EPROMs that are in it are probably Matrix
and/or I/O ROM IIRC. That seems to be standard in the 9915s that I'm aware of.
>>>
Yes, I have a programmable-rom-module and assembler rom (but have not tried
them yet). A buddy of mine has managed to read 85 roms and burn them into
eproms for the prog-rom-module. The original 85 roms seem to be special,
and cannot be simply duplicated.
I opened up a rom, hoping to find a standard package, but found a chip
covered in a blob of epoxy, attached directly to a small board. I opened
the rom drawer card, and found that all six sockets are wired in parallel
(no individual enable lines to each). Then I looked at the signals
connected to the rom card connector (using the serial manual's connector
pinout as a reference). The roms have +12V, +6V, and -5V power. There is
an 8-bit bi-directional bus, and four non-overlapping 12V clock signals.
There is a "load-memory-address" line, a "power-on" line, "read" and
"read-control" lines, and even a "write" line (I don't know why write is
available on a rom).
This all leads me to believe the roms are pretty specialized. Since there
are no lines to enable a specific rom socket, I think the 85 must poll for
roms using fixed address ranges or something -- this implies that the roms
contain address qualification circuitry of some sort. I'm just
speculating, but it would make the roms very difficult to duplicate, since
this is not a standard address-bus/data-bus (or even a typical multiplexed
addr/data bus).
Thanks for the info Joe,
gil

I opened up my keyboard and traced out the circuits again today. I HOPE this is right, I haven't double checked it. Everything in caps is as it appears on the keyboard. Names that are too long are abbreviated and shown in lower case. A list of the abbreviations and their meanings is also shown below.
pin 21 20 19 18 17 16 15 14
2 nu kl K1 K2 K3 K4 ^ da
3 1 2 3 4 5 6 7 8
4 Q W E R T Y U I
5 A S D F G H J K
6 sb Z X C V B N M
13 nu nu -l da -CHAR REP -> <-
12 nu RESET bs nu = - 0 9
11 nu nu nu sca ) ( P O
10 nu nu nu nu el ' ; L
9 nu nu nu RUN PAUSE ? > <
Abbreviations:
nu = not used
da = down arrow (up and down arrow are used to recall previous commands and for editing)(I just noticed that I have this listed twice so there's probably an error there somewhere).
k1 = Key Label
el = End Line (this is what HP uses for carriage return/Enter)
sb = space bar
bs = Back Space
-l = -Line (erases the entire line)
sca = Scratch (erases all memory, just variables, etc depoending on what argument you give it)
Notes: The K keys are programable function keys. K5 through K8 are K1 through K4 shifted. You can assign programs or functions to these keys and use the Control input lines to trigger the program or function.
The -Char key erases one character at a time.
the REP key toggles between the insert and replace modes.
There are a few more keys that don't fit into a matrix. Here's a list of them and the two pins that they connect to:
Both SHIFT keys are tied together in parallel and connct to pins 18 and 7.
There is a 8 Ohm .2Watt speaker inside. It connects to pins 25 and 7.
CNTL key connects to pins 23 and 7.
CAPS LOCK key connects to pins 24 and 7.
I'll try to photograph the keyboard and post the picture tomorrow so that you can see what the layout and key legends and shifted legends are.
The HP 10269B/C General Purpose Probe Interface is just a physical
interconnect between the pods and various probes. The B version is for the
old style HP 1630 pods. The C version is for the HP 1650 all the way
through current style pods.
I think the 10342B just buffers the HP-IB signals and I think you could use
the config and IA files just without the probe. For the RS-232/449 signals
it uses a dual UART (I forget which one) plus the Z-80. I assume the Z-80
is there just to configure the UART. Some day I'll dump the eprom on the
probe just to see what it actually does.
I have a manual and the config and IA files for the 10342B. If there isn't
a scanned copy of the manual on the web I should send a copy of the manual
to someone who can scan the manual and make it available on the web.
I also have a 10314B 80386 proble which mates with a 10269B/C and it has a
bunch of active electronics. I don't have config or IA files for it. Does
anyone else? Not that I have a real need for it nor do I have any 80386
systems (at least not at the moment.)
The HP 10277 might just be a physical interconnect to your own custom
interfaces, if I correctly remember what that thing is.

I dug around this morning and found two logic analyzer pods/CPU adapters. These are boxs that you plug the pod of the logic analyzer pods directly into and they usually have a cable that plugs into the CPU socket of the UUT. When using these you don't use the flying wire leads and grabbers.
One is the HP 10342B Bus Preprocessor in the HP 10269B General Purpose Probe Interface. This is for the HP 1630 and 1631 series LAs. This particular preprocessor is used for monitoring RS-449, RS-232 or HP-IB busses and acquiring data directly from the bus. You can replace the Bus Preprocessor with various CPU adapters.

The other logic analyzer pods/CPU adapter is a HP 10277 and is for the HP 1610 sereis LAs. It's a single unit and it doesn't have any active parts in it. However it has connectors for ribbon cables to connect the the test bewing tested and I don't have the cables so it's POSSIBLE that there may be some active parts in the cable or something attached to the other end of it.

I can't find now, but I have a hard copy).

If you want a TMS3417 bad enough any of the parts brokers (e.g.
http://www.aecsales.com) should be able to get you some. Usually these
places have something like $100 minimum orders.

Hi all! I just discovered this mailing list a couple nights back.
Now I have a place to share my cool classic comp acquisitions. :)
Anyway, last weekend, when I reported to my squadron for our monthly
drill, I was informed that one of our officers had brought in a whole
bunch of old computer stuff that I might be interested in (he's
moving across country and isn't able to pack it with him.)
I had a great time sifting through the massive amount of classics
that were stacked at the back of the dining hall, and deciding what I
should claim. Since our little apartment here is short on storage
space at the moment, I just selected a Cromemco System Two and a
Cromemco System Three, as well as a box of various S-100 cards,
manuals, and disks (including a complete set of Cromix-Plus and Unix
System V floppies.) Had I realized that the thing that looked like a
jerry can, which I thought was most likely a power supply of some
sort was actually a Cromemco hard drive, I would have taken it along
with the Cromemco System One that was sitting in front of it as well.
Oh well, live and learn. :/
So the next day, after final roll call, I load up the stuff in the
truck of the guy who gave me a ride home, and me and my roommate that
afternoon start looking over everything. We were disappointed that
the System Three was totally stripped of all cards (though it does
have a pair of 8 inch floppy drives). The System Two on the other
hand, was a different story. Not only does it have a pair of
floppies, but it also has a 21MB hard drive, 3 256K RAM cards, and a
couple other cards I can't remember at the moment. Since we are in
need of some cash at the moment, we went ahead and put some of the
excess stuff (spare manuals, extra cards, and the Fortran 77 and
68000 C packages up for auction. We might also sell off one of the
256K cards that's in the System Two as well. But that isn't the
point of this post (not wanting to turn this into a FA posting,
y'know).
We are looking forward to one day having the room to set up the
System Two and actually making her a part of our little home LAN.
I'm predicting that this is going to be a long term project, much
like restoring a classic car. I suppose the most important thing I
need to get for her is some sort of terminal/control console.
Fortunately, dumb terminals show up at the thrift stores around here
every so often, as well as other interesting bits of old computer
parts (I have an IBM 3274 Terminal Controller set up as a TV stand in
my room. For only $10, it is a much cooler piece than the usual bits
of overpriced furniture Goodwill normally gets...)
I'm also wondering if this little honey could be used as a console
for the Cromemco system...
http://www.oz.net/~otter/gallery/Geek-Console.JPG
Sorry. Can't remember what model number it is at the moment. It is
way too heavy for me to move by myself so I can see the label on the
back. :p
As for the System Three; we haven't decided what to do with it yet.
It doesn't have enough stuff with it to make it worth the hassles of
auctioning (plus, without having an operational car at the moment,
shipping would be an enormous logistical challenge.) If someone can
come pick it up (Kitsap County, WA), I would be open to some sort of
reasonable buy or preferably trade offer; especially if I could trade
it for a Commodore PET (been wanting one of those ever since I saw
one back in the old days on an episode of Buck Rogers, and later in
the background
in Kirk's apartment in Star Trek II:
http://www.oz.net/~otter/images/scr-st2-1.JPG
Anyway, enough incoherent babbling from me for now. Time for me to
catch a bit of sleep.
Later!
-- Scarletdown
P.S. If anyone is interested, I can send off an email to someone at
my squadron Monday Morning to find out where that Cromemco System One
was donated to.
I recently accquired an Osbourne 1 computer. I turned it on and it
seemed to work, I was able to boot BASIC off of a floppy and I wrote a
couple little programs, (print hello world, count to ten, and count
forever, stuff like that). The picture on the screen was kinda dark in
spots, and while the computer was counting, it flickered to a very dark
and barely readable, then it went black all together. I tried turning
up the brightness and contrast controls, the only one that makes any
change on the screen is the brightness control. I can see the rasters
when the brightness is up all the way, but the contrast control has no
effect. The computer seems to still work though, I can turn it on, then
hit enter and it will boot from the floppy. Previously, when it was
working, I noticed the screen flicker when the computer accessed the
floppy drive. My guess is that there is something wrong with the power
supply. Does anyone have any ideas? I would really like to get my
Osbourne working again, it's a really cool little computer.
Thanks!

Hi
I've notice these as being a common failure item, as well.
I don't think it is the voltage that is killing them. It is
more likely a timing overlap issue with other parts driving
the bus and stressing these parts. One might consider adding
some resistors in series ( small value ) to limit the current
when a tristate drive also drives the bus at the same
time as the '05 is active ( driving low ). I would suspect
that something in the order of 15 ohms would be enough
to protect the '05's and still drive a solid '0' onto the
bus lines.
There is no reason that any voltage issue should cause
problems with these parts.

I can't help from personal experience (my ASR-35 from N.J. hasn't made it
home yet - it went from The Armory to Canada and should be in Ohio by
the end of the month), but I can make the suggestion that it sounds
like a dirty contact in the output rotor or a broken/disconnected
lever under the keyboard. Looks like you are missing 2**3 in your
parallel->serial conversion, but I couldn't guess at what stage.
I do not own nor am I expecting any ASR-35 manuals. Perhaps the
Greenkeys list mentioned elsewhere might be useful to you for securing
a set of docs. I'll have to be hitting them myself when my 35 shows
up. I'm certain it's in need of a PM cleaning and lube, and I have *no*
idea how to do it at the moment. (The TTY itself still has strapping
tape on the carriage and protective film on the cover - except for a
test sheet, it looks virtually new. Still needs a lube job, though).

Hi
I've only fiddle with my ASR33. You need to find out what
is wrong first.
As an example, my ASR33 takes the output of the keyboard
and passes that to the distributor at the back of the machine
to serialize. The parallel output of the keyboard depends
on a bunch of switches that are located at the side of the
keyboard. These switches are exposed to all the gunk that
usually floats around in a teletype. I'm sure you may find
that one of the switches is dirty and just needs cleaning.
Until the signal is serialized, the problem can be anywhere
>from the switch on the keyboard to the brush on the distributor.
This includes the connectors. Some tracing with an ohm meter
( power off ) will most likely find the problem.

The A11 light dosn't function due tyo a blown 7405 chip in the front panel. I have had to replace several of these myself on my altair and on my IMSAI. 7406 seems to make a better replacement as it can take higher voltages
FWIW,
The GA-16/220 is a computer that is used in the Excellon CNC-4 ,
CNC-5 , and CNC-6 consoles. These consoles controlled the
Excellon Drilling/Routing Machines.
www.excellon.com for more info.
My most favorite was the AT&T 5620 with a host running layers. Even without
layers, the 800x1024 page-sized screen was nice. Second would be a Tek
4207...fun graphics. Favorite "normal" terminal would be an amber phospor
VT420.

I dunno, I prefer TIFFs, but they have the disadvantage of being honkin'

Hi Stefan:
You may be interested in the greenkeys teletype email list -- lots of good
folks with questions, answers, etc. (I am admin of it). Let me know if you
want more info. You could join and ask, or I could forward your message if
you'd rather. There is likely someone on greenkeys who can help you.
I'm not personally familiar with the 35 (though it's just an ascii version
of the baudot 28). The 35 is a heavy-duty machine that you should be able
to return to service (as opposed to the 33, which is a crappy design that
just wears out). I'd love to see some pics of your 35.
There was a guy in NJ last month with two 35 machines on ebay. He could
not get $5 for them, and may still have them.
I have collected a few teletype machines that I am restoring (not selling):
an M15-ksr, an M31-ksr, an M33-asr, an M28-ksr table-top, an M28-ro, an
M28-rotr, an M28-td, an M14-td, and an M14-ktr.

I would doubt AT&T handles support for a 3400, since it is an MP-RAS
machine, and I *know* NCR retained MP-RAS... I'm fairly certain that I saw
System 3400 docs on NCRs website when I was looking for Tower manuals..
