All of these are gone, except for some AC adapters.
Some Tandy 1000 series left.
No Apple II or IIe, just lots of Apple/Mac laptops.
Lots of classic IBM compatible laptops, from 8088 to P3, various stages of
completeness, mostly untested.

While I'm prepping parts for P112 kits, I started thinking about DE-9
pigtails. These things come in two different pinouts. One of them is
pin-1 of the header connects to pin-1 on the DE-9. When wiring up a
pigtail like this manually, you cut the ribbon cable into two sections.
One sections goes on the top row of the DE-9. The other section goes on
the bottom. The other one has the pins interleaved. See
http://661.org/p112/files/pigtail.pdf for what I mean.
The P112 was designed with the second pinout in mind. When I bought
pigtails for my first run of P112s, I managed to get that kind. For
subsequent runs, I always got the first kind. Which pinout is more common
with actual devices? I ask this because I'm tinkering with an amateur
radio project that will eventually use DE-9 pigtails.

Here's another long shot: Does anybody near southern California have one of the Radio Shack computer desks that were configured to hold a Model II that they might consider parting with, like the one in this catalog page?

Hi ?
Thought I?d see if there were any list members who could provide background information on the Data General DG10.
We?ve received a working system as a donation, but there?s no software or documentation with it. I understand the hardware was very specific to the model since it used a MICROeclipse coupled to an i8086. What I don?t know is whether we need to locate model specific disk images to run AOS or RDOS on it. Also not sure how specific application code has to be. It would be useful to find service manuals, programming manuals and media.
I understand Wild Hare Computers was working on an archive, but there doesn?t seem to be much in the public domain as yet.
Can anyone offer any guidance?
Thanks

Has anyone ever seen any detailed tech info on the TRW/Motorola CPUAX,
circa 1989? It's mentioned in Motorola's annual report and in some
trade journals, but I can't find any info that wasn't just press
release stuff.
While I wait for PROMs to arrive for my 11/05 I've pulled another
"back-burner" project off the shelf.
It's an Interact Model One (http://oldcomputers.net/interact.html) and
it's having power supply issues.
The symptom: At initial startup after being off for any significant
period of time (say, 10 minutes or longer) the +5V comes up for 2-3
seconds then drops to zero. The other supplies (+/- 12V) are fine.
What I've done so far:
- Recapped the electrolytics in the supply (I had the parts on hand,
and it's three capacitors. Sorry for the shotgun approach, Tony :)).
- Removed socketed 2114 RAMs (in case one was shorted).
No change in behavior. The power supply and logic are incorporated into
a single PCB, so it is difficult to separate the two (I guess I'd have
to figure out what traces to cut, and I'd rather not mangle things if I
can avoid it). The DC supply is fed by an external "wall wart" which I
*believe* just contains a transformer -- it outputs several flavors of
AC (16.5V and 19V), no DC.
Any suggestions for where to start with this? Power supplies are voodoo
to me, still. The power supply schematics can be found in here:
http://www.thebattles.net/oddments/interact/InteractSchem.pdf (page 6,
lower right corner).
Thanks!

Just like your misleading post about the LM309's output being connected to
the 8V supply rail, you had specifically said that "there aren't *any*
resistors connected to it, which is why it's sitting low. I checked that
out." No mention of the 470 ohm pull-down resistor...
Maybe you could save some time by checking more carefully before posting...

Many years ago my father recovered a whole lot of documentation from a
PDP-15 system at Philips in Stockholm that unfortunately already was gone
(scrapped or given away).
The lot is several meters worth of shelf space. I have put a photo of the
cover of one of the manuals online:
http://www.datormuseum.se/documentation-software/pdp-15-documentation
I checked bitsavers quickly but didn't find a matching document. Are these
documents already online somewhere or should I bother go through the whole
lot and document what kind of document there are?

Hi Retro fans,
I have a cache of retro computers I wanted to grant access to the internet. As we all know, utilities exist to open and send TCP sockets to a serial port (Jim Brain's TCPSer is awesome), but getting them to work right on a Mac can be challenging. So, I wrote my own:
http://cassarasoftware.com/serialtcp-for-mac/
It's rather bare bones at the moment, but gets the job done. I hope it helps everyone looking to get their old stuff online!

In the early eighties we got a unit which we think is a Incoterm SPD 900
intelligent terminal. At that time it was running just fine. Until now we
had it in store but it has not been tested again lately.
Now I would like to see if it is possible to get it running again. It is
quite interesting in that it is a display unit with built in computer. The
CPU is a Incoterm proprietary implementation with a core memory. Attached
to this display unit there is a disk unit that employs hard sectored
diskettes.
The machine was running an operating system called SPD/DOS. Actually there
were all sorts of software for this machine as I recall. Even small games.
An early personal computer in some sense.
When searching the net I came across this post
http://marc.info/?l=classiccmp&m=104965775322087&w=2 by Al Kossow. Well
now, more than 12 years later, I can confirm that the disk found by Al is
>from an Incoterm system running the SPD/DOS system.
Anyway. I have put together a page with some information on it:
http://www.datormuseum.se/peripherals/terminals/incoterm-spd-20-20
If there is anyone that can enlighten me more about this unit I would
appreciate it. If there would be engineering drawings available I am very
interested.
During my searches on the net I found this page with mostly ex Incoterm
people disussing:
http://www.vintagecomputing.com/index.php/archives/33/window-to-the-sky-the…
Another interesting thing is that the SPD/DOS reference manual still can
loaned from a library in Sweden.
http://miks.kib.ki.se/search*swe/?searchtype=X&SORT=D&searcharg=SPD%2FDOS&s…
Apparently at Karolinska Institutet in Huddinge south of Stockholm. Maybe I
should go and find it there...
The reason for being available is probably that these terminals were used
by the Swedish LIBRIS II system at several libraries in Sweden.

are, I think, 256 x 1 ECL static RAMs.
Also a bunch of new in original tubes National

Hello Everyone,
I am new to the list although some members will know me from the Erik's
VCFs. I recently acquired two 5322s and a 5120 and amazingly all three work
to some extent.
1. My first 5322 blew the filter caps 30 seconds into powering it up. I am
waiting for replacement parts.
2. The second one seems to be stable but the drives may have errors - they
fail the ROM based diagnostics.
3. My 5120 is actually working well except the screen jumps sometimes so I
am guessing the PSU is shaky (no pun intended) at best. I don't know enough
about the system to do anything more complex then run the prerequisite
"Hello World" program.
I have been looking for documentations, HMS, programs etc. for either of
these systems to help in troubleshooting and repair. While the 5110 (type 1
and 2) and to a smaller extent the 5100 documentation is available as PFDs
the other two systems have been ignored for the most part. Any help is
appreciated in the form of actual physical product, digital info, or even
personal experiences.
I am also looking for the bottom half of the back portion of a 5322 if
anyone is parting one out.
Thank you.
I recently downloaded and installed MorphOS the Amiga Compatible
operating system for PowerPC G4 systems. So far its really cool,
Especially if you are into Amiga, You can run most classic amiga
software on it natively :), If you got a spare iBook G4 or old G4/G5
based system laying around, Give it a look. Its a ton of fun to work
with :)

Hi
I'm restoring a MicroPDP-11/73. I've made some initial notes here:
http://www.pdp8.se/pdp1173_restore.shtml
The ON/OFF rocker switch is broken. Three small plastic teeth that hold
the springs in place have broken of and a forth is cracked and will soon
break. I've tried three different kinds of glue without a getting a
strong enough bond. I will make another attempt with a fourth kind.
But, I wonder if these are available somewhere? The only marking I've
found is "UND.LAB.INC.LIST" which seems to be a brand with several
different kinds of rockers, some available but not the one used on this
MicroPDP-11. By the looks of it, the same switch is used on MicroVAX. In
the meantime I will probably take one from a spare machine.
I'm borrowing a picture from the net here, but it is like the switch
labled "1 0" here:

Howdy folks,
I'm just about in the final stretch of my Altair 8800 restoration (more
like a total re-construction..) and there are a couple of parts that I
obviously need to pick-up.
FYI, this is a 'to factory' restoration, so the 8800 is going back to where
it was when it was built from a kit. This isn't totally true, as this
particular unit was later fitted with the "B" power supply and that will
remain. It's obviously far superior to the "A" version and I don't have any
of the A PSU parts.
First off, I need a static RAM board for it. Ideally, I'd like a 1K or 4K
MITS part.. but any +small capacity+ static board will probably fit the
bill, particularly if it's has hand-drawn traces and is built on the
clear-whitish board material as is the Processor board. I'm not sure what
to call this color or type of board.. so please chime-in.
Secondly, I'm thinking really hard about replacing the motherboard (or as
MITS called it the 'expansion board'). As it sits, it has a Processor Tech.
MB-1 16 (!!) slot board that's going to look a little silly with only two
or maybe three cards plugged in it. Does anyone have an original 2 or
4-slot mainboard, or even a 3rd party board that's not so dang huge?
So to this end, I have a few items to trade if that would work. There's a
64K (max 256K) dynamic RAM board, a Z-80 board, a floppy disk controller
board, what looks like an RS-232 board, and a couple other minor items. All
parts are in great shape, look ready to run.
TIA for any and all help. Feel free to contact me off-list to work out
deals.

i happen to have gotten windows 95 installed on my old panasonic toughbook cf-27 but i have one issue where the drivers i need are a bit to large for a floppy disk and even trying to compress the files in a 7zip or a zip file does no good. i still need an audio driver and the pcmcia card slot driver to install. also i wish i could find a usb driver for my iomega zip 100 usb zip drive for windows 95 but thats not possible and since lenovo took over iomega they dropped lots of old drivers. i have tried to track down iomega drivers but i end up at sites that claim they have the driver only to be given an installer to a driver program thats a scam. maybe someone out there could help i still need the audio driver which is a yamaha sound card and windows 95 claims its a creative when its not also i need the pcmcia driver.
>...Phil Katz and PKZip...
I still have my original copy of PKZip with manual. Here is an example of a
"post-vintage" yet historic software killer ap whatever you want to call it.
I agree that this is/was a very important piece of software and should be
recognized. Here's to Phil!
Even though they're off-topic here, I still make a point to archive the
1990-1996 software that I found useful. Many of us back then used to carry
around our super support disk that almost always included pzkip, pkunzip and
pkfix, laplink (ll.exe), and many others. From a preservation standpoint, I
have saved these disks "as they were" because they help put things in
perspective. I also had early Win 3.1 TCPIP windsock, BTRIEVE, editors,
etc. PCTools disks, etc.

I'd like to get at least 2, and preferably 4 or more, MM5204 EPROMs.
This is a 512x8 that isn't pin-compatible with anything else (except
the MM5214 masked ROM). Does anyone care to sell some, or know a
seller?
If all else fails I could make adapters to use a more modern part, but
I'd rather avoid that if possible.
Thanks!

Hi folks,
I impulse bought this thing locally a couple weeks ago, then realized
I have no IBM gear to go with it :[
It's a really cool piece of kit, but I've just moved and could really
use the space.
Just want to get back what I paid for it: $50 + actual S&H.
I get a pretty great discount on shipping through work, so even for a
big nasty terminal like this, it should be pretty cheap.
Unit is in good condition, powers on, comes with keyboard.
A couple keycaps are missing, and someone yanked the keyboard jack off
the board, but it's been bodged back on and appears to work. Anyone
with a soldering iron should be able to do a better job re-connecting
the jack, although it appears to work as is.
I just don't have time or room for the damn thing. Located in 98105
(seattle) if anyone local wants it-- or I could hold it for a bit if
anyone will be in the area soon.
Please respond off-list.
Cheers,
- Ian
P.S. Hope for-sale posts are allowed-- been a CCtalk reader for a

I've been playing with a couple VaxStations and a qbus PDP11 recently
and have been having trouble with connecting 10Mb ethernet to 100Mb
and 1Gb switches. I have several 10base-T transceivers that I use
since all my 10base2 hardware is in storage.
Today for example, I connected a DELQA in the PDP11 to a 10-100-1000
switch and it did not work. I got out a 10-100 hub and put it between
the PDP11 and the switch and it worked fine.
Another example, my VS4000/60 netboots fine, but NetBSD will not
detect the network interface unless it is connected to the "right"
switch.
All the switches and hubs I am using are from a collection of
unmanaged consumer grade stuff (TRENDnet, ASUS, Linksys, etc.) that I
have accumulated.
Curious if anybody else has similar trouble when mixing old with new
and slow with fast.

I just got a VT240 with a VR201 monitor. When I switch it on it displays
"??240 Monitor Error - 9" (although the question marks are reversed).
The terminal works otherwise. It displays the setup menus, and it works when
connected to one of my VAXen.
I have looked in the docs I have, but none have troubleshooting information,
and I can't find anything online.
Any idea what this error means?
Incidentally, I used to use a software package called UNIRAS to do graphics
on VAXen, does anyone know if it is still possible to find this software?
Anyone got anything to exercise the VT240's graphical capabilities? I
believe Datatrieve has something, but I don't want to install that just to
test the VT240.

Don't have one of those or I'd use it. Did a quick google on the P/N...
http://www.upgradebay.com/Products/ProductInfo.aspx?ProductID=169290343
Um... $255?!? They are on the drugs.
Yes, I can make one. No I haven't made one. A list member is sending
me a real Sun3 kb this week.
Of course now that something is moving on this, I wonder if I have a
suitable monitor...
I know I have a working Viking Moniterm I (and the Amiga card to go
with it). Apparently, on this very list, it was mentioned 13 years
ago that the monitor has DIP switches for its timing settings
(1280x1024 @ 60hz was apparently common, and as used with the
A2024-compatible adapter, 1024x800 @ 60Hz or 1024x1024 @ 50Hz)
http://marc.info/?l=classiccmp&m=104957388722023&w=2
Anyone know if it'll do 1600x1100 @ 66Hz or 1152x900 @ 67 Hz? Even
if it can, would it require an ECL->TTL level converter for the video?
A quick google is not revealing tech docs for the Moniterm I (but
there's plenty of cautions out there that they fail often).

Somewhere in the last couple of days I saw mention of a terminal emulator program for the TRS-80 Model 1, but I don?t remember what it was or where I saw it. I didn?t think about it because I was able to get kermit on the TRS-80, but I just pulled it out again and kermit kinda sucks. It types in all uppercase unless I hold down the shift key, and it?s got no cursor.
Anyone know of something that?s better?

Hi all,
I'm trying to repair a bunch of DEC RL11 controllers.
(These are the UNIBUS boards for RL01/RL02 disc drives).
Running the PDP-11 diagnostics ZRLA, ZRLB, ... ZRLN from XXDP or
papertape prints out some errors,
but without the diagnostic assembler listings I don't understand what's
wrong.
At the moment I know only of these 4 listings:
AC-E040B-MC_CZRLBB0-RL11_RLV11-Controller-part-2_Oct78.pdf
AC-E044B-MC_CZRLCB0-RL01-Drive-Test-part-1_Oct78.pdf
AC-E048B-MC_CZRLDB0-RL01-Drive-Test-part-2_Oct78.pdf
AC-E246B-MC_CZRLEB0-RL01_RLV11_Exerciser_Oct78.pdf
These are all for paper tape based MAINDEC diagnostics, and are also
incomplete:
At least both "part 1" AND "part 2" is needed for ZRLB, ZRLC, ZRLD.
Can you point me to some hidden archives?
Or do you have more assembler listings for ZRL diagnostics lying around?
Bitsavers needs your input!
Thanks,

Three new Sun binders scanned tonight with a pair of special docs this
time. It's all been software previous to these but tonight we have
the elusive (at least I couldn't find it) Sun PROM User's Manual (doc#
800-1736-10.) This one has lots of juicy info going back to the Sun-2
(including the LED flash codes I'll need to diagnose my -2 boards) up
through some of the Sun-4 series and the 386i. I'm sure a lot of that
info is out there in FAQs and Usenet posts but this may be the source
of that knowledge in one place (not to discount personal experience.)
There is also a system diags manual that spans a few platforms as
well. And riding along with these two is the "Editing Text Files"
tome, covering your favorite editors of the period.
The filenames are here:
800-1736-10_SunPROMUsersManual_RevA09May1988.pdf
800-1738-10_SunSystemDiagnosticsManual_RevA09May1988.pdf

Hello ccmp'ers - July is almost here and that means it's time for me
to start making noise about our yearly Midwestern weekend-of-fun.
This year's Vintage Computer Festival Midwest will be held a bit
earlier than in previous years, owing to the usual scheduling
conflicts with holidays and other events. The weekend for 2014 is
September 13-14.
Those coming from out of town and staying over night should call the
hotel ASAP. Registration at the group rate has been open a few weeks
now but last I heard rooms are still available.
If you would like table space, please email me privately with your
requirements and what you'd like to display and or sell. Most of the
provided tables are 2'x5'. If you can bring your own folding table,
please do! We run out of tables before we run out of space to put
them.
We've got a new site up with actual content, including an
ever-expanding FAQ. Have a look and feel free to post about anything
not covered there:

Those were actually two different options. The grey back panel came standard
with all 5170 AFAIK. Since they were only put on by Velcro most are lost
(like the front lock keys). The tower option (or as it is formally known:
Personal Computer AT Floor Standing Option 6450218) allowed you to stand up
the 5170 on its side. In fact you cannot use both the grey back panel and
the Floor Standing Option together. Check out VCF - I have pictures of both

I am very pleased to announce, and be done with, the scanning of a

various months from 1990, 91 and 92. They're full of ads for "The

the products of the times. The articles cover a wide range of topics
(and how they're accessible on their service) as well as predictions
of CompuServe's existence for decades to come. Not much mention of
this "Internet" thing...
Due to the size of the files and the ease of reading documents in
their browser, I uploaded the scans to archive.org instead of our
usual docs site. All of the issues should be accessible with this

Hello, all,
I am in the midst of restoration of a very old (1964-ish) electronic calculator called the Wyle Laboratories Scientific Model WS-02. This is a transistorized electronic calculator that uses a magnetostrictive delay line for register storage, and a CRT display for showing the working registers and memory registers. The CRT is driven by sine/cosine signals to generate fully-formed stroke-style digits. I don't know if it's magnetically or electrostatically deflected...is there any easy way to tell? There are some coils around the neck of the CRT, but they are not as large as I'm used to seeing on CRT's of this size (8").
The question that I have is that I want to test out the power supply circuitry to make sure that all is healthy there. I have removed the logic module from the machine (the logic module contains all of the calculating and display generation logic, and comes out as a unit). I have also disconnected the video driver board. The connector at the back end of the CRT is unplugged. There are a couple of wires that go to the coils around the neck of the CRT, but they are connected to the video driver board, which is disconnected. The high voltage connector from the flyback is still connected to the CRT.
At this point, I've traced out the main logic voltages (+12, -12) and a -30V supply that are used throughout the machine.
I want to slowly bring up the power supply with a Variac and monitor the voltages and ripple to see if the power supply is still healthy. However, I'm concerned about having the high voltage supply connected to the CRT without any other connections on it? Could the high voltage supply be hurt because it may be missing signals it needs to oscillate properly? Could this hurt the CRT? I don't know enough about the way this kind of stuff works to know if I could cause any problems, either with the CRT, or the high voltage supply.
I'd appreciate any guidance that may be given prior to trying to light this thing up.
Thank you,
Rick Bensene

It's obvious - two people used it at once for a couple of years.
Presumably they had half the keyboard each, and fought over the

I found a TU-60 tape with what is apparently CAPS-11.
The tape label has the following texts :

A loose label lists the (apparent) contents date 09-aug-73 :
CTLOAD SYS 08-aug-73

I've imaged a little stack of Displaywriter 8" disks and am starting in
on filesystem organization. With an EBCDIC filter I can see the data
plain as day. I've also got experience stitching together the
DisplayWriter files that come from the DOS-based system, so if I could
get the file allocation scheme figured out and lift off whole files from
these disk images, I bet the same conversion code would work on the
resulting data.
I've browsed the manuals on Bitsavers, but of course IBM never intended
their users to actually look at the bytes on the disk. So none of the
information was geared towards revealing the file allocation secrets.
Is there any reference material out there to help me decode (or find)
the file allocation structures?

Hi all --
As I mentioned a few days back, I recently picked up an 11/05 that's in
need of some troubleshooting. This weekend I've started getting more
acquainted with the details of the CPU set (reading through the
schematics and the various manuals (which are quite thorough, fortunately.))
Before I start getting too deep with this, I figured I'd see if maybe
I'm overlooking something simple -- I'm relatively green with Unibus
systems.
So here's what I'm seeing:
- At power-up, the system comes up in a halted state and I can load
addresses from the front panel switches into the address register, and
these are correctly loaded -- no stuck bits, etc.
- Toggling "Start" causes the "Run" light to go on and the system seems
to be doing... something (the address/data lamps flicker). Attempting
to halt the machine at this point does not work, but if I have the
"Enable/Halt" switch set to "Halt" and hit "Start" again the machine
does stop and the "Run" light goes out.
- Hitting "Exam" while halted has no effect (no data is loaded,
addresses are not incremented), and seems to lock the machine up -- I
can no longer load addresses via the front panel. Hitting "Start" still
puts the machine in the "Run" state outlined above, and once halted
again, "Load Addr" works again.
- Hitting "Cont" while halted puts the machine back in the "Run" state
regardless of the state of the "Enable/Halt" switch.
So it definitely looks like the Run state control logic should be looked
at...
The machine's configuration is very basic: the CPU set (M7260/M7261),
an 8KW core board set (G110, G231, H215), and an M903C Unibus
terminator. I've verified that these are all in the correct slots. Bus
grant cards are in the D slot of all four Unibus slots (and inserted in
the correct orientation, I hate those things...)
Thus far I've tested the power supply and voltages are spot on with
acceptable ripple. AC LO L and DC LO L are correctly going high after
power on, so that shouldn't be causing issues. I've gone through and
cleaned everything including the edge connectors. (I left the core
plane undisturbed, it's already been banged around enough...) I
double-checked the backplane for bent pins that might be touching other
pins.
I've checked the processor clock, and it's running properly and at the
correct rate (310ns). I've run the machine with just the processor set
with the same behavior.
Any other simple things I should check before I get seriously involved
with this thing? Fortunately I have a set of KM-11 replicas I got from
Guy Sotomayor a few years back so that will help immensely in debugging...
Thanks as always,
Josh

On the back of that, are CRTs best shipped with the screen facing down, or
forwards? Presumably it's also wise to unplug the neck board from the CRT
and secure it. What do people do about the HV transformer? They're normally
bulky/heavy and can lack support other than the solder connections on the PCB.
I?ve shipped tons of stuff through The UPS Store. They always do a great job packing.?

the package is a case of disk drives.
Is it a Coke/Pepsi-style thing, where the carriers some how lock in their

won't/can't put up with UPS' sad excuse for service, so expect less
business from me. (Sometimes you just don't have a choice.)

Hello,
I have a VAX 4000-100A (54-21797-01) that gives P-cache errors.
I would try to understand if the problem can be fixed somehow,
or if the CPU / motherboard needs to be replaced.
Anybody has NVAX CPU datasheets, including pinout to check if there's
something
wrong with basics like power supply, cache invalidate signals, etc?
Thanks

Was there more or less a standard or reference 6502 assembly language (e.g.
>from MOS) with regard to syntax and pseudo ops? With the cpu being used in
so many different computers, and so many vendors writing their own
assemblers for each platform, did the assemblers tend to resemble each
other (besides the instruction set), or did everyone tend to do their own
thing?
Opening the rom cartridge is a little tricky it's holding together through four rivets. You need to heat them before they can be removed, there is a big change you will damage the housing.
But with some glue logic it should be possible to read the rom with a programmer. And I know at least three 98228A ROM's, one in Australia one in the UK(London area) and one in the Netherlands ;)

Hello Mark,
well I suppose it would be very useful for this kind of operations.
And as the whole read operation would be in the control of the PC,
you could retrieve the whole disk, or a part, or a single sector..
whatever you want.
The first step is to debug it and let it work with SIMH.
Then I will try it with my 8" double floppy unit.
At this time, adding support for any other drive would be a matter of
knowing the peripheral
control registers and producing a set of scripts from these informations.
I will keep you informed about it.
Thanks
Andrea

I have a Tandon TM-848E 8" floppy drive which appears to have become a disk lathe. Or perhaps just an effective disk eraser. It's one half of an external dual 8" drive unit that I picked up off eBay several months ago. I've cleaned the heads, and I can't see any sharp spots or debris with my head-mounted magnifying lenses, but it continues to scrape rings in the oxide of a disk on both sides. I haven't tried removing the heads to put them under my microscope since that would destroy the alignment.
I've only tested it with the pair of disks that came in the drive so far. It's possible that they are bad disks with soft oxide, but I haven't seen the same scraping problem so far in the other drive of the pair. So, that one drive appears to be a disk lathe now. I haven't felt up to risking a potentially good disk in the bad one.
Have any of y'all seen this kind of problem before? Is it likely to be repairable, even if that involves removing the heads and then realigning the drive when I reinstall them? Or is it most likely that the drive is fine and I've just been putting bad disks in it? I don't have any alignment diskettes yet, but I may get some one of these days.
For the time being, I'm assuming that I'll just use the drive as a source of parts for other TM-848-series drives in my collection, like one that I have with a broken latch handle. The other drive plus the enclosure is earmarked for use with my KryoFlux.

Hello,
i trie to copy a binary file with 6kw length from my Linux PC to a TU56
DECTape. The TU56 is connected via TD8E to the PDP-8. I work with 9k6.
Every time i try this, the transmission stops.
What id on PDP-8:
.R PIP
*DTA1:CHESS.BN<PTR:/B
^
then on Linux i send plain Chess file.
Do i need hardware flow controll on RS232? Any other helpfull hints?

The IBM 3278 terminal that I've been waiting for is now officially lost. UPS even said so!
What I found out is that when you track a package on UPS, most of the "scans" you see
are logical scans. That is, where UPS *thinks* the package is. UPS doesn't actually
know where a package is unless there are "physical" scans. At certain points in a
package's travels, there will be occasional physical scans but they are not as often as
UPS's tracking would imply.
It turns out that with my 3278 terminal, there was not *one* physical scan. The folks at
UPS said that is *very* unusual. It could mean that it's sitting where the shipper dropped
it off (here's hoping) and never actually went anywhere.
It's not like it's a small package (145# in a wooden crate). So it's not likely to have been
misplaced. ;-)
The other thing that I found out about UPS, is that they don't really want to talk to the
receiver. They only want to talk to the shipper. Fortunately the shipper in this case has
been really helpful and willing to deal with UPS on my behalf.
So, anyone know where there's an IBM 3278/9 terminal available? ;-)

When we tried something similar on an 8/I, and it also failed. It worked OK
after we connected the reader relay logic on the console to RTS/CTS on the
PC and enabled flow control.
You could make an image of the DECtape using SIMH and then use David
Gesswein's resttd8e. One part of the program runs on the PDP-8, and one
part runs on the PC. No hardware flow control is needed.

Well this is slightly embarassing....I knew I had some sort of
non-HPIB HP floppy drive downstairs. I just went to search for it
and...it's a 9885. So, in theory, if I got the parallel interface (a
few for $50 on ebay now) and the 98217, I'd have a complete system.
That is, if the drive works and I found the (also rare) formatter
tape.
It would see it would be better to hold out for the HPIB-enabled 98228
ROM, or as Glen says above, maybe someone will clone it.
Fortunately this is only a hobby and there are plenty of other
projects to attack. This one can wait :)

I have 85 P112 boards pre-populated with surface-mount parts, but no parts
bags. If I can pre-sell just seven kits, I can order enough bags to make
forty kits. Eight more than that should be enough to fully fund this
project for the rest of the boards I have on hand. This will probably be
the last time I do a run of P112 kits, so get them while they last.
P112 kits may be purchased from http://661.org/p112 by using the handy and
secure Paypal purchase button. If you'd rather not use Paypal, email me
at dave at 661.org and we'll work something out. Price is $190 for inside
the US and $210 for outside the US. As before, Terry Gulczynski is
available for assembly services and expansion boards. His page is linked
>from mine.
Kits should ship approximately two weeks after ordering to account for the
fact I need to order the parts bags.

I have a lovely HP 9825B desktop "calc-puter," the "T" version which
includes a number of ROMs that would have come on a cartridge in the
earlier models. There are a number of ROM carts and interfaces on
ebay for the 9825s, among them the "98217A Flexible Disk Drive" module
and the 98034A HPIB interface.
My question is: is the latter interface, along with the General and
Extended I/O ROMs already built into the 9825B, sufficient to talk to
HPIB floppy drives? Or do I need the 98217A, or some other ROM, to
add the disk routines to HPL?
The 98217A says it's specifically for the 9885M 8" disk drive. I
don't know if it has other applications or not. I don't have a 9885M
or the interface module that would be required.
Thanks for any clues...

Where do you guys & ladies recommend taking a minicomputer to be
professionally packed for shipping? I have a Data General Eclipse
S/130 that I need to ship about half way across the US, but I need to
get it professionally packed to avoid shipping damage. I plan on
shipping the front panel, the boards, and the chassis (with PSU in it)
as separate packages. I'd like to find a place that can use the "foam
in place" around the wrapped components in the inner box and/or around
the inner box. There is no terminal/monitor.
How do you recommend packing the minicomputer to minimize the chances
of any damage during shipping? The computer is free, so all funds can
go towards the professional packaging and shipping. Who do you
recommend? If it matters, I'm in north central Florida.
Thanks,

Dear friends
In my never ending quest for a joystick for my Apple computers, I got a
Gravis joystick with a strange din connector on it. Now I know I need some
"gravis programmable box sbrubbles sbrubbles something" to connect it to,
and so to the computer
Does anyone has any refferences about it? I can clone the box if I have
at least the pinout of that connector. And of course, I'm open to offers of
the original box
Thanks,
Alexandre
(still dreaming with an original apple joystick, and an ANKO one) :oP
Bob,
I had good luck with a Forward Air pallet last year. At Lowe?s, I bought cheap nylon straps with tensioner buckles and some bubble-wrap, and some stretch wrap. I brought a couple of old cardboard boxes to cut up into pieces to pad any contacting parts. I put all of the equipment on a pallet at the Forward Air depot (they were kind enough to let me work off in a corner for an hour or two). Here?s the process:
1) put straps under pallet (actually through, being sure to include the structural beams of the pallet)
2) pile big gear on pallet, in a vaguely pyramidal shape - cardboard ?padding? where they will be pulled together by straps or rest on one another
3) bubble-wrap small pieces and stretch-wrap them to big pieces
4) connect straps over top, more cardboard padding where each strap turns a corner
5) tighten straps until they are about middle ?A" when plucked
6) run laps with the stretch-wrap until the pile is coccooned to be certain no cables, etc. stick out or fall off.
Ethan was the recipient, he should chime in for how well it survived. It looked OK when it left.
*Some* day soon I need to do this again?. sigh.

A PDP-11/05 in need of some help arrived on my doorstep yesterday.
Amongst its other problems (*) the power/panel lock microswitch has been
broken beyond all repair and it's kind of an oddball thing -- anyone
happen to have one going spare (or know what the equivalent might be?).
Someone did a rather ugly kluge to work around it (it's just hotwired in
an always-ON configuration with a really ugly jumper wire), and I'd like
to get it operating normally again.
It's marked as DEC P/N 12-10982 (REV. B).
Thanks in advance,
Josh
(*) It's been dropped (or had something dropped on it), the frame is
bent as a result, which I've mostly undone. The power supply tests out
good (a small amount of ripple but within tolerances if the service
manual is to be trusted) and it shows signs of life (Load Addr works
about 50% of the time), however it's not doing much. The M7261 board
has "BAD?" penciled in so someone else's been over this machine before.
I sense a lot of debugging in my future.
My best Commodore monitor, the 1084, went belly-up on me today. It's been
showing sings of trouble for quite a while, but this time it finally failed
over.
Nothing worse than an intermittent..
Symptom was a little non-intuitive. The video would go out, randomly, and
all at once - like flipping a light switch. But when it would return, it
returned more slowly - it faded in, as if the CRT heater were warming-up.
Now, if the heater were losing power, why wouldn't it fade +out+ as well?
But I checked, and the heater was definitely off - no glow, no voltage at
the heater pins 9 & 10.
Anyway, it turns out that this is one of those sets that draws its heater
supply from a second winding on the HV flyback transformer. After some
inspection of the board, I found that one of the flyback's soldered
mounting pins had cracked at the joint, causing an intermittent connection.
This was the cause of both symptoms - a quick cut-out of the video when the
HV disappeared, and the slower fade-in as the connection re-made and the
heater warmup lagged the HV rise.

I have a monitor for a Stardent workstation. It's a re-badge Sony, model
number 130-0001-01.
Free for pickup, or 1.2 * cost of shipping to recoup time and trouble if
you want it shipped.
Please respond soon if you are interested as it will be going off for
scrap in a week if there are no takers.

> ... Terminal emulator for TRS-80 Model 1?
I found two manuals, but I'd need to track down the actual software here,
depends on what kind of Model 1 you're talking about, new or old (disk or
cassette). A quick check revealed:
Modem 80 (disk program requires 32K and disk)
"Mostly BASIC - Interfacing / Scientific" which is a telephone dialer
cassette program by Howard Berenbon.
The Tandy modem must have come with something to dial the phone? I am sure
I could find at least one or two more.
It's on my short list to archive TRS 80 1 disks (III and 4 too) now that I
have an imaging station and I have largely finished the 8" disks I have
left. I have a lot more 5 1/4" software but it'd be worth the effort.
Bug me if you want me to bump the comms utilities I have to the top of the
list.

When I needed some one inch paper tape, I watched Ebay. Found several boxes
in just a week or two, reasonably priced. Was even able to get the yellow -
lightly oiled and the heavier oiled black tape.

I have been buying my shipping supplies from U-LINE for years and have
always been impressed with the service and pricing.
When I can't get to the right size box I sometimes use free boxes from an
area liquor store. I went to the post office last week to ship a few boxes
to a list member and was told they could not ship any kind of booze box
unless wrapped in a grocery bag or painted over.
When I had my UPS account, or used fed-ex, they took them. They just
worried about previous shipping info on the box.
I tried another post office and the same thing happened.
Has anyone else had this problem?
Thanks, Paul

Todd doesnt understand that USPS does not consider floppy disks media
mail anymore, There are 330lbs total of floppy disks, And 500lbs of
documentation, he doesnt realize that it will cost hundreds of dollars
for them to be shipped across the country, Yes he did pay for the disks
and some shipping, but it wasnt enough to cover it. And i definitely
am not going to pick up the tab to ship these things out of my house.
Yes I want them gone, I have 330lbs of them sitting here. So if he
wants to come get them when I am kid free, that is fine.
As far as the eviction is concerned its none of anyone's concern but if
Todd wanted to see the judgement all he would have had to do was ask.
And I go to VCFMW every year, Its none of his concern about making
hotel reservations, Im not the one paying for it, my gf is.

The bare TTL RS232<>BT devices start at < $5.00

True RS-232 < $15:
e.g. 400706121660
I've used both with no issues.
For RS-232<>Ethernet I prefer a used Lantronix UDS-10 or equivalent; more
professional configuration options/software than the current Chinese stuff.
You used to be able to pick them up for around $20 if you kept your eyes
open.
e.g.:
131252594914
271574124592
Or maybe:
191248187972
No problem putting pretty well anything with a serial port up on the
Internet; the Lantronix devices are pretty flexible but not all other
devices handle handshaking properly and buffer overflow can be a problem.
I've logged into a CP/M system in Australia with a Tandy M100 laptop in
Toronto ;-)
And then there are the RS232<>WiFi adapters...

I'm very sorry to hear of your family situation, and wish you the best. I
think you're making the right choice, the only choice one can make as a
human being. Thank you for all you've done for vintage computer
preservation. -- Ian

You know, this originally looked like a dream come true? until I realized
that I'm either draping a CAT-5 cable across the room, or a serial cable.
I have some 50' MMJ serial cables, and the adapter ends to plug them into
things. True, I already have an Ethernet infrastructure in the room, but I
can also hook up a terminal server where I have some machines that need it.
I can't think of any scenarios where I want to be further than 50' from
one of the machines, but for one - and my 11/73 and VAXen have Ethernet.
I looked up RS232-to-Bluetooth and there are devices, but there a LOT more
expensive. I'll just keep schlepping cables around the room, I guess, at
least for now. -- Ian

I am using a standard DL11-W for the TU-58 serial interface, but
modified it to support a 115.2kb data rate. This means that for
each incoming character the 11/34 has about 90usec or so to process
it. More than enough time to read it from the DL11-W, store it in memory,
manipulate some counters, etc.
The XXDP TU58 driver can handle this, as it is not interrupt driven,
it is polled. I haven't tried the RT-11 TU-58 driver at this rate, but it
may have issues as I believe it is interrupt driven. It would be an
interesting experiment.
On the host side I am using my TU58EM program on a PC. It can easily
handle the 115.2kb serial data rate.
This is a standard 11/34A with MS11-L MOS memory array, no cache option.
I have been using this configuration for a few weeks now and have seen
no issues at all in loading and running XXDP diagnostics from this
emulated TU58 device.
My mod is not specifically described, but there is at least one web page
out there that describes modding the DL11-W for higher baud rates. That
page described the crystal and divider changes, but did not go as far
as changing the UART to a newer version capable of 115.2Kb.

Awhile back there was a lot of discussion abt DEC LA75, LA310, etc. I do
have some DEC dot matrix printers here, if they are still wanted, I will get
a list together.

For once, the ?Grumpy Ol?? is perfectly warranted.
Get well soon! I rejoice whenever I see your tag on a message -
I know something good is coming. I hope to read a *lot* more of them.
