I'm having some odd problems with a 7906 drive. I have the service manuals,
and it passes all the tests contained therein. However, none of those tests
involve writing, and reads done offline with the DSU are not verified. The
read/write testing relies on the diagnostics running on the cpu. I have the
diagnostic software for the 7905/06 drives and it does find problems
(sporadically). However, the dump it gives when it finds a problem is
somewhat less than succinct - looks like you have to have the manual for the
diagnostics to decode the dump, which according to the service manual can
point you to a specific circuit in the drive electronics.
Sooo does anyone possibly have the documentation/manual for the HP 7905/06
diagnostic program? Hoping for electronic format so I can look at it
quickly. I'm itching to get to the bottom of this.
I've got a single 486DX-33 CPU chip and a single 128K (64k?)static RAM
chip (IS61C64A-25b - ISSI mark). You don't even have to pay postage, just
claim it so I don't have to toss it. Comes in a nice little box with
anti-stat foam on the bottom.

There's a big pile of RCA COSMAC development boards, mounted in rack
chassis, with "many" options (ROMs, memory, LED displays, power
supplies, etc) at the Black Hole in Los Alamos. Aka Los Alamos Sales Co.
I neglected to say some months ago, and it just popped into my head now.
I have the big fat RCA manual. I just have too much stuff ("just one
thin leetle mint sir!").
While I don't usually search eBay for this sort of item, a friend mentioned
something to me which prompted me to search for something magtape related and
I ended up bidding on this item and winning it (eBay will be my death):
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2762437052&ssPageName=AD…
Anyway, I'm wondering if anyone can tell me what vintage it is and what
equipment it was used in? Pictures or URLs would be a bonus...

I agree. Which is why I suggested Trinity College or somewhere in Stamford.
Anything else closer to NYC proper would be too expensive.

Bob,
There are several single port terminal servers
available. I have used the PicoWeb and the
HelloDevice. The PicoWeb server is cheaper and
available from www.picoweb.net, but he did not
reply to my last emails. Instead we bought the
single port hellodevice model ls100 from www.sena.com.
the PicoWeb site has complete schematics etc. The
HelloDevice LS100 is more of production device. Its
also easier to setup and use.
>From memory, the PicWeb Server was about $90 and the
LS100 was about $130.
If you need lots of serial ports, perhaps a standard
terminal server would be better. Speaking of which,
does anyone know of a MOPD server for Windows 98?
Max

I suppose, if you want 16-32-48 ports and a big honkin' box. I was
hoping for 1 port and a tiny box.

Dear m-r Duell,
I'm looking for disk drive model MP-F52W-00D (Sony).

Your advice is necessary
Best Regards, A.Marder, engineer
I want a little gizmo with an RS-232/DB25 on one side and a RJ45/10baseT
on the other. It should speak TCP/IP, specifically telnet, and convert it
to RS-232. Kind of like a print server, except for telnet/RS232 instead of
lpd/Centronics.
The idea is to use it to put some of my old computers on the network
by plugging it into their console serial ports.
There are enough microprocessors around today with embedded TCP/IP
stacks that such a thing would not be that hard to build, but it
sounds like the kind of thing that somebody else must have already
done.
Can anybody give me any pointers to such a gizmo?
Thanks,

Hi All,
Had an Atari 520 ST in storage. Found out it has small ants next taking up residance inside it. I think I found it before the ants managed to cause any damage inside the unit, however am courious to know if there is any known long term affect from Fly Spray contamination. I can clean up most of the PCB and Everything with the usual High presure wash, then dry it in a drying oven, but what residues am I likely to have from fly spray?? Any one with any ideas????

Hello, all:
I'm doing some renovation work on the Altair32 Emulator and I'm
looking for JPGs of Altair-era dot matrix printers that I can convert to BMP
and use as a dialog box background.
It would have to be a close-up, well-lit shot that I can re-size if
needed. The final size won't be any bigger than about 640x300 (more likely
smaller). A shot from the operators' viewpoint would be best so you can see
the control panel.
Please contact me off-list. As always, thanks.

In other words, a terminal server (or a console server, as they're
sometimes called). Look for a secondhand Shivaport or Lantronix; don't
bother with Emulex.
If you want a really small one, try
http://www.interfaces.de/e-wwwww-ww-hpus-000.html
(but they ain't cheap). They do some nice things; I bought some web-IO
thermometer units from them (I use PT100 probes and I can run the
probes remotely over 100m of Cat5).

Hi folks,
I'm looking for either an HP-1600A manual, or for some kind soul
to give me a few pointers on how to use the 1600. I got it without
the manual; but I do have all the probes.
My main questions are:
a) what do the "Qualifier" switches do?
b) how do they relate, if at all, to the "Trigger Word / Map
Locator" switches?
c) how do I trigger on various patterns (if I can)?
d) some explanation of the "Trigger Mode", "Sample Mode",
"Table", and "Map" switches.
e) any other general operating tips would be appreciated.
I'm posting to this list because I figure a few people out there use
these things for their antique computer collections; I certainly plan
to use mine to restore my PDP-12 :-)
http://www.parse.com/~museum/pdp12/pdp12/restore.html
I intend on using it with a "clothes-pin"-type 14 and 16 pin adaptor
to check on the operating state of various ICs...

All the rails I've ever seen have some way of separating equipment from
rail; usually catches that can be undone to allow the unit to come
right out the front. I've seen some rails where the catches were hard
to find, hard to get at, hard to figure out, but never one without any
catch or release mechanism at all. It wouldn't make sense: if the
equipment is so heavy and/or delicate that you couldn't risk it falling
out, you don't want to make it too hard to mount in the first place.

How would I check to see the ROM configuration? Configuration includes
12821A disc controller, BACI, HS terminal, BUS I/O and a bunch of I/O
cards, also 3 64K word memory cards. I don't have docs for this box but
I have what looks like a complete set of manuals for a truly embedded
system - an HP 5987A GC/MS (gas chromatography/mass spectrometer)
system. Manuals include the RTE-6/VM manual. I bought manuals and
cables; the CPU itself may still be available (I think asking price was
$300) if anyone is interested.
BTW, this thing is really too big for my collection - anyone want to
trade a MOS KIM or Exorciser system for it?

There are two or three types. One has panels that pop on using springy
metal fasteners, one has sides that lift up slightly then pull off,
similar to (but not the same as) the taller racks.

Normally, on those racks, you use clip-on Tinnerman nuts, with 10-32
screws. Some devices use a metal strip with tapped holes to take 10-32
screws. A Tinnerman nut is basically a folded piece of springy sheet
metal with a nut welded onto the back, so that it clips onto the
vertical rail and holds the nut captive and aligned with the hole in
the rail.

Pity you haven't got the original rails, they're really high quality.
Eagle rails are heavier-duty than most, but any really HD rail will be
fine, providing the holes fit.

Within reason, it doesn't matter. I'd leave a gap above the Eagle. In
case you didn't already know, the rack is measured in "U" (units of
1_3/4"). 3U is 5_1/4". If you look closely you'll see the holes are
not evenly spaced, but in groups of three. The centres of the outer
holes of a 1U space are 5/8" distant from the centre of the middle hole
(and distance from centre of outer hole of one U to centre of outer
hole of the adjacent U is 1/2" ).

15A should be plenty. I can't remember what an Eagle draws, but my
11/73 system draws less than 4A at 230V, but it has two smaler drives,
not an Eagle. The normal way to wire them up is with a power
controller in the bottom of the rack, at the back. A power controller
is basically a power strip with two sets of sockets (one always on, one
set controlled), a 2-pole (3-pole if for 3-phase) circuit breaker (not
just a switch), and a relay/contacter and associated electronics. A
3-position switch lets you turn the contactor to ON, OFF, or REMOTE,
and there are two or three 3-pin AMP Mate-N-Lock sockets for remote
connections (you can wire the BA11-x switches to turn the contactor on
and off).

Lo and behold, when cleaning up a bit, I found an original Microsolutions
"uniform-pc" 5.25" floppy. Serial 01720511.
Someone asked about it lately, but I cant remember who it was.

No, if they''re the normal Eagle rails, they *do* come apart. The
normal method is to separate the outer (main) assembly, fit it, with
the back bracket, to the rack, and get two people (or possibly the
industry-standard pile of books or wood) to lift the unit to the
correct height, while you guide first one side and then the other into
the fixed part of the rails. It's often easier to get the drive lined
up, close the front of the cab, then slide the rails onto the drive,
rather than wiggle a 200lb drive onto a moving (sliding!) target.
Are these rails made of what looks like brushed aluminium alloy, about
3" high? Slide the outer part back; it will stick out about half the
drive length. You should have an inner (actually, it's the middle)
layer of slide, with round-bottomed grooves on top and bottom edges
(where the ball-bearings run), probably still more-or-less aligned with
the front and back of the drive. This slides backwards (it's much
stiffer to slide than the outer section, and goes "click" as the safety
button engages in a round hole (abut 3/4" diameter) near the front of
this middle layer. At this piont, the amount of rail extending out
behind the drive is just a little more than the depth of the drive
itself. Press the button in, push back some more, and the whole
middle+outer of the slide will come off the drive.

Yes, there are. Some racks have the verticals closer to the front,
some (comms racks) have them set further back ( to allow for a door
closing over cables plugged in to patch panels. And there are shallow
racks, instrument racks, deep racks, ...
Add to that, different methods of ixing. As you look at the rack from
the front, you see a flange with the mounting holes in it (one on each
side of the rack, obviously). Some things are meant to fasten to the
front surfuce of this, some to the rear. Many types of rails fit to
the rear surface, otherwise they'd be too thick to get standard-width
equipment between the rails. The standard rails for things like an
RX02, a PDP/8E, modern Intel 2U servers, etc fit to the rear surfaces
for this reason.

I think that's what I've just described, and you've obviously

Usually, the way is have a strip of steel, about 3/8" wide, and about
1/8" thick, with three of four tapped (threaded) holes in it, spaced to
suit the rack's mounting holes. If the front bracket (or flange) of
the rail has slots instead of holes (they usually do), you pick the
holes you need, put a couple of screws through the rack, and screw them
just a few turns into the metal strip. Do this front and back. Then
adjust the back bracket to about the right length, slip the rail's
flange between rack and metal strip, hold in place with one hand and
tighten up the screws (you want Philips head screws, not slotted :-))
with the other. Same at other end, then add more screws as required.

Ok, so I was at the Computer History Museum again today and got a chance
to check out the Unidisk in more detail.
First of all, it might be a very late model prototype as it requires a
kludgy external box for power.
Donated along with the drive was a box of Apple interfaces. There is
definitely an Apple /// Uni/Duo-disk controller. Therewas also a funky
Apple ][ riser card. There were also a couple extra analog boards. One
was a spare Unidisk analog board, and there were two Lolly Disk analog
boards. What's a Lolly disk?
Also donated were about 10 engineering drawings of the Unidisk, Duodisk,
as well as the Disk ][ controller, Disk ][ analog board, and some other
stuff.
Definitely an interesting piece of hardware.
Eric, ask the next time you are there and you should be able to get
someone's permission to check out the drive. It's in the accessioning
room, next in queue to be accessioned.

Hi folks,
Well, the haunted house season is over and the cleanup continues.
Now I'll have more time to put into the HP2000 simulation project.
As you may remember we did get HP2000 Access running under simulation, as
well as "E" and "F". But so far no one is running a system full time.
I was running the system under Windows, but Unix and Mac are supported as
well. We have most all of the documentation including the source for Access
date code 1812, and should have most all of the contributed libraries.
Would any of you have access to other HIBE tapes? Ether in your archives or
in archives of data centers you used to support?
We still have more HIBE tapes that need to be converted to CD ROM and lots
of work sorting it all.
It sure was nice the first time I launched a telnet to my windows box and
got the "PLEASE LOG IN" prompt, and it was even better once I has able to
log in and play Adventure.
Since the simulation is faithful to the hardware, the original operating
system binaries don't even know that they are not running on real hardware.
I even have to use an image of the actual 2100 paper-tape bootstrap program
to get Access running under simulation.
With this approach to the simulation, every feature, flaw (if there were
any), or quirk is faithfully reproduced.
I'm trying to get HP to allow a hobby use open license, but until then the
package is available only on an as needed basis.
Do you know anybody who may want to play sysop and keep a system running for
the public to play with?
If so, just drop me a note.

Ps. We also did a paper on the project, which can be found here:

Probably not at Home Depot, but specialist hardware suppliers (any rack
supplier) will have them, or Tinnerman Palnut themselves. Try a Google
search for "tinnerman" :-) Or see if any local suplus places have any
(look for them still attached to racks).
You'll find that using ordinary nuts and bolts is often very difficult,
because you often can't get your fingers in to hold the nut.

Correct, there are usually three (or four) screws at the front, and the
same at the back. If you've got two parts of the rail, one sliding
over the other, you're just missing the back brackets. If you've got
only one part, fixed to the side of the drive, you have slightly less
than half the rail (you're missing the larger part, with all the ball
bearings, and missing the back bracket). The back brackets are plated
steel channel, about 8" long, that fit over the stationary part of the
rail. The end is bent over into a flange that bolts to the inside of
the rack's vertical member. I dare say you could make something that
would do the job.

I think Al said
he might have found some reference that proves that the IOP firmware was
actually ported by HP to the E. Can you confirm?
--
The part numbers for the E version appear in the 2000 section of the M/E/F CE
manual. It has 6 proms listed instead of 12. I still think it's possible to
convert the MX version to the E. Bob and Mike figured out what the instructions
do (from memory something like cnvrt isn't even used..)
My computer is up and running 24 hours. I have some particular interest
to play with the HP2000, and sould like to get the package to put it
online (and play with too).
Cheers

Hi
I've looked at your site but I'm a little confused. How does
one use the Museum page? Also, how does one find information on
a computer that one is looking for? What is a WIKI?
On your page, you mention that one should be willing to pick up
any machine that is offered. While this is a nice thought,
I couldn't even justify the price of gas to pick up a
no name 286 PC. I don't know anyone that would pay shipping on
such a machine. I would cost me extra to bring it to the
land fill transfer station that I go to because these are
considered hazardous waste. Under these conditions, I don't
think I could consider myself a curator for your page although
I would otherwise love to post my collection.

Hi Dave
First thing to concider is that this was a carbon-zinc battery. They
expect a large voltage difference over the life of the cells. Stacking
two 9 volt alkaline batteries should be enough to make the unit operate
properly, giving 18 volts. If you find a problem here, you can always
cut open a 9 volt alkaline battery and remove enough cells to make
up the 4.5 volts. The alkaline units have separate cells that can be
individually removed. This is unlike the stacks that are used in
9 volt carbon-zinc batteries. Be careful to leave enough welled strip
to solder to so you don't over heat the cells.
Later
Dwight
I have an old Triplett 631 VTVM/VOM (that I use with classic computer
stuff, of course) that uses a Burgess XX15 battery. The XX15 is 22.5V
and is no longer made.
There is a "fix" for this situation posted on the Web that substitutes
several currently made 22.5V batteries. But, I'd like to see if there
are any other ways of replacing the XX15s.
So, does anyone have an old spec sheet for the Burgess XX15? I couldn't
find anything on the Web.
Thanks,
Dave
There was Multi-DOS by Vernon Hester, it worked on
Model I/III/IV
He also made a simple version called V-DOS (I think)
for Game manufacturers.
Percom also had Double-DOS
There were quite a few more, Percom had it's own
incompatible DOS for awhile also.
And then there were the various CP/M flavors for the
TRS-80 like Lifeboat, Lobo, and others.

I am looking for a troubleshooting guide web site or similar resource. Or
maybe someone here can help?
In a nutshell, I turn on the Apple IIe and drive 1 spins and the drive
light comes on, but does not read any bootable disks. On the display the
screen reads: Apple ][
I have a number of boot disks so I don't think the disks are all bad. I
have checked the cables and the drive card. I have swapped out the drive
card with another that works. I have swapped cables and they seem OK.
How do I diagnose the condition of this computer?
Is there an internal diagnostic? (key combinations?)
What's wrong typically when a disk drive spins but nothing happens?
Playing around with key combinations I found that control+clear
apple+filled apple+reset brings me to a prompt of some kind, but I do not
know what I can do from this prompt.
I have no manuals.
I would be happy to send a set of digital pictures to anyone interested in
helping.
Please email comments to billdeg(a)degnanco.com - thanks!

Well, the main part is the Acorn MOS (Machine Operating System), and to
that you can add various filing systems: DFS is the single-density
floppy disc non-hierarchical Disc Filing System, ADFS is the
double-density floppy/hard disc hierarchical Advanced Disc Filing
System, NFS is the Network Filing System, you can guess what ANFS
stands for, TFS is the Telesoftware Filing System (for software
broadcast as teletext), ...
You could also get the UCSD p-System From SofTech/TDi.
For the Torch Z-80, there was CPN, a CP/M lookalike.

Yes, it does. It gives my Amazon associate account whatever small commission. I am in the process of rebuilding all of my links to computer history related books from Amazon and for abebooks.com. This small commission in no way costs the buyer any more, and my desire to share the great deal on a great book was sincere.
