Following on from my previous post re punched cards, thank you for replying.
I am following up where I can.
Now, however, I realize that the IBM Port-A-Punch requires a special type of
cards. Does anyone have 1 to 3 of these they can spare. (I already have the
instrument.)
Many thanks,
peter

Sorry, which exact quad-height CPU card?
{As someone else has previously pointed out, the /73 and the /83 are basially
the same machine (roughly the same CPU board - KDJ11-B, perhaps with different
clock crystals), just with different memories - QBUS in the /73, PMI in the
/83. The /84 is an /83 with i) a different backplane and ii) a KTJ11-B UNIBUS
adapter.}

I would advise against that. 256K chips are readily available on eBait, and
for not much money. Pulling them may damage them, and may well also do some
damage to the memory card, in addition to making it useless.

A vacuum desoldering station will easily open them. Used Hakkos can be found
on eBait for not too much money.

Favor to ask: Would anyone have MPW running in some environment, such that
if I give them a PEF file they could run dumppef on it and get the symbol
table exports and such? The format is documented and I can write python to
pull out what I need, but would be so much quicker if someone had MPW
installed and running already..
Thanks in advance!

I have posed this question to the 8lovers list, and folks seemed to
misunderstand. So let me try here.
I believe sometime in the late 70s, maybe as late as 1980, a prof
associated with UMass wrote a paper describing an extension of the
PDP8 called 8/X or 8X.
THIS IS NOT the Pre Nova/DG machine but a completely different concept.
THis is not the FPGA pdp8 implmetaton that also has an X in the name.
I believe, my memory is fuzzy, that it was a prof nnmed Stone or
Stoner (perhaps Harold S) who lead the effort and had his name on the
paper.
My fuzzy recollection was this was PDP8 with a Cache, an extension of
the instruction set, maybe to 24bits, and full compatibility with
8/e-8/a. I recall the spec citing a 10mhz (100NS) cycle time. some
sort of start up setting that would make it 8 mode or X mode on start
up, don't recall if it could switch modes while running.
I had a copy of the papers some where and it is misplaced hiding on
one of my computers and I am bout to pull out my BigMac that might
have the data in it.
THanks for any hints as to the online location,
Again, this is NOT the pdpX concept that led to the DG or the FPGA
system or the spartan 3 based system, it is just a concept paper.
Thanks

All,
Next to go is a box in which a Palm Pilot was originally sold.
The box is in great shape, shrink-wrap intact except where it was sliced just enough to open the top.
The manual is in great shape.
The registration card is in great shape.
The order receipt is in great shape, name of original owner mis-spelled but otherwise apparently correct.
The accessories catalog is in great shape.
The software on 3 each 3.5? floppies and on CD appears to be in great shape (not test-read yet).
The Now Sync accessory software, on 2 more 3.5? floppies, appears to be in great shape.
The leatherette protector is in great shape, with its foam insert still inside keeping it shaped for the Palm Pilot.
The DE-9 to DB-25 serial port adaptor is in great shape.
For Pete?s sake, the screen protector that peeled off the Palm Pilot screen is in great shape,
lovingly tucked into the manual.
You have probably noticed what is missing.
There are no electronics included.
No Palm Pilot, no charging/syncing cradle.
Grrrr.
You probably want this if you picked up the Palm Pilot at ShopGoodwill somewhere, want to re-create that 1997 ?first on the block with a personal digital accessory? feeling and really enjoy going through the accessory paperwork.
https://www.shopgoodwill.com/Item/87198940
(but I think that is a different model).
Free to a Good Home, preferably one with an actual Palm Pilot. Shipping will be from San Antonio TX, 78254. If as I suspect, nobody interested, headed to the trash. Standard rules, I?ll wait for a week or so, ship to the sender of the first email in my in-box or to Al K if he emails before I ship.

Hi Doug,
I'm in Melbourne and have several working PDP-11's. I can send you a couple
of bootable RT11 8" disks. I'll need to know whether they are RX01s or
RX02s though. Perhaps send me an email offline and we can take it from
there?

Since a few days, my EXORciser Development System is finally able to boot from floppy diskettes.
Previous attempts have shown that the Motorola EXORciser M68SFDC1 floppy disk board used has a special modified ROM version. This was probably written for an 8-inch drive, in which the Write protect and Direction signal were inverted.
For the sake of simplicity, I have used free inverter on the board to invert the signals accordingly.
After adjusting the PLL frequency, reads and writes from the card are now error-free. And all without FDC, only clever programming by Motorola software engineers in the early 76?
Originally, the EXORdisk system was a dual drive with two 8 "units. This I have replaced with a double drive of two 5.25 inch units. An Epson and a TEAC, which can be jumpered to 360 rpm. Luckily, 2HD floppy disks are easy to R&W.
I also got a GOTEK floppy emulator running, which I can boot from. Thanks to Roland Huisman, Bitsaver has some interesting floppy disks that convert to HFE format work perfectly. This format makes the Gotek drive most reliable.
Now to my question. The vintage computer forum at http://www.vcfed.org/forum/archive/index.php/t-44638.html mentioned some interesting manuals. Archive.org has some manuals, Bitsaver does not have manuals about the M6800 development system.
If someone already owns scanned manuals to the following list
M6800 Basic Interpreter Reference Manual
M6800 Macro Assembler reference Manual
M68SFDU Exordisk 11/111 Disk `Drive Unit Maintenance Manual
M6800 Exorciser 11 User's Guide

I would welcome any feedback or questions

Chris,
Congrats on the PDP-11/84! I also have a PDP-11/84 that uses one of Joerg?s Hoppe?s
UniBone devices to simultaneously emulate MSCP disks, RL02 disks (including the
RL02 Load/Ready/WriteProtect/ and fault lights) and a DL11.
I have a question about something you said above, that you are using a MTI
ESDI disk controller and then you mention Qbus block mode DMA. Are you able to use a
Qbus MTI controller in the 11/84?s Qbus section of the backplane? This is something
I?ve often wondered about but never tried.
Also, you mention putting the PMI memory above the 11/84 CPU. In the 11/83
Qbus backplane this is of course determines whether the M8637 memory is accessed via
Q22 or PMI. In the 11/84 System Maintenance Guide Figure 2-8 shows the
CPU card above the memory which if you were to do this in the 11/83 would mean
that the memory will be accessed via Q22 and essentially become an 11/73.
In my 11/83 I have run both configurations to understand and measure the benefit of PMI.
As has been mentioned the 11/84 can use any of the M8637 memory boards but the
11/83 can only use the M8637-D or -E versions. For anyone who is curious about what
Happens when a M8637-C version board is used as PMI memory in an 11/83 I can speak
>From experience. This was running RSX11M+ and it boots fine but after a few minutes if
The system is active, the console starts to report that various installed tasks are corrupted
And the system will XDT a bit later. After this the disk is corrupted and you will need to restore

(I was using an Emulex UC07 with a SCSI2SD) into the disks but that is what happens.

I've come into possession of an HP 41-CX calculator - unfortunately it
appears to have had batteries left in it which have left corrosion on
the internal contacts.
(some pics: https://photos.app.goo.gl/48bE7WJZP8R4PF9a9 )
My classic hardware tendencies tend to run more towards the "can run
*nix" end, and while I could just clean it up and throw it on eBay I
wondered if anyone here has a 41C shaped soft spot and would be
interested? (happy to trade/part trade for something they already have
for which they are less fond if that works :)

Old IBM magnetic media
I am hoping someone can help me with a project. I?m volunteer at our local
music museum (National Music Centre/Studio Bell.) They are restoring a
vintage Synclavier, an early digital audio workstation, which happens to
have an embedded DEC PDP 11/23. Part of the museums purpose is to restore,
maintain and make available these instruments for musicians to use in
addition to static displays.
The Synclavier should have a matching VT100, but that is the only component
the museum does not currently have for this functioning device. Yes, the
VT100 can be easily emulated, but as a museum, historical accuracy is also
vital.
I was wondering if anybody had any leads on a VT100 that might be donated?
Thanks for any help!
Anyone seen Rik Bos around? I sent him some 12920/21 mux boards to repair, and he got to keep some but haven?t heard anything in a long time?. I may start playing with the HP2000 again soon ?

Yes, two cartridges have a total capacity of 100mb, the same as the staging
disks, IBM 3330-1.
However, the entire cartridge contents are not staged, only the cylinders
that have the requested data.
Not sure why your cartridges were empty.

So I picked up an 11/84 CPU, 3mb of memory, and a 11/84 Unibus card on
Ebay. Goal is to speed up my fastest 11 here
For boot time, the diagnostics run in 13 seconds (from when it starts to
prompt) on the 11/73 board I have and 13 seconds on the 11/84 board.
This is with a camintonn 2mb half height memory board.
Put in the first PMI module above the 11/84 CPU and tried it out. This
is a CA rev board which apparently only works in a Unibus pdp11 and not
a Q-bus one. Apparently it does work.
So what exactly was the bug with the older PMI memory? Block mode DMA,
I'm using an MTI ESDI controller which can do 16 word block DMA on Q
Bus. Something else?

Guys,
I have been collecting all types of computer punched cards for a few years
now. In the distant past I actually used them!
I am desperately looking for two types I do not have been able to find a
sample of:
* Jacquard fabric/carpet loom cards. OK, not computer but the
ancestor, for completeness of the history. There may be several formats of
these.
* Original Hollerith card, 12 rows by 24 columns. Once again, this is
a long shot.
Well if you don't ask, you never get! Thank you for your interest. Peter
I have another PSU I have been meaning to look at for a long time. This one
has fairly high output ripple and some of the voltages do not appear to be
where they should be. I have checked all the capacitors for ESR and they
appear to be OK, with the exception of the two big smoothing capacitors on
the primary side. One of them appears to be slightly bulging, but has
low-ish ESR, the other has a much higher ESR. Is it possible that these
capacitors could be the cause of the out-of-spec outputs?
Thanks
Rob
Some of you may recall seeing me post about the VAXmate PSU failure. Thanks
to members of this list I found the failed part in the PSU and the PSU is
now working again. However, it looks like the PSU failed because of a
failure on the monitor board. There is a burning smell coming from it,
possibly the flyback transformer, but I am not 100% sure. I don't see
physical damage, but of course that doesn't mean there isn't a problem. When
I took the monitor board out again after this, I wasn't sure if the EHT lead
was making good contact with the CRT anode. The monitor board is described
in section 4.4 of this document:
http://bitsavers.org/pdf/dec/vaxmate/EK-PC500-TD_VAXmate_Technical_Descripti
on_1987.pdf
I need some advice on diagnosing the problem, I have a few questions:
1. If the EHT lead was not properly connected to the CRT anode, could
that cause problems?
2. Is there anything I can safely do with a bench power supply to
isolate the problem?
3. Any other suggestions for diagnosing the problem?
4. There is an outline spec of the flyback transformer in the section
4.4.3.2 of the VAXmate technical description, what chance of finding a
"modern" replacement?
I have posted about the PSU repair here:
https://robs-old-computers.com/2020/04/18/vaxmate-h7270-psu-fixed-but-no-vid

That is probably Harold S. Stone, whom I knew as a Stanford prof in
the early 1970s and did some corporate consulting with. Brilliant
guy. From 1974 to 1984 he was at UMass Amherst, so your memory isn't
fuzzy at all. He also worked at the IBM Yorktown Heights research
center. He was the author of several books and many papers about
computer architecture, algorithms, and interfaces.
Unfortunately I don't remember him working on a PDP-8 extension, and
a quick search of the ACM Digital Library turned up nothing. As far
as I know he's still alive at the age of 82.
I have been sorting thru a bunch of stuff in an effort to
clean the place up (Aren't we all doing that now with all
this time on our hands?) I found a backplane. It says
Digital on it but does not have an H- number. I also
don;t find it listed in any of the lists I can find on
the web.
It has 8 A-B slots and 4 C-D slots. the Four C-D are on
the bottom half of the backplane. I am assuming it is
18 bit and the C-D were intended for things like the 2
board RL controller.
Anybody familiar with this and able to identify it?
Anybody interested in it? It should fit in a USPS
Medium Flat Rate Box.

Hello. I have both, Rolm CBX System Service Manuals l and ll as well as a Release 8/8001 Student Maintenance Course binder. Are you interested in these??Thank youSent from my LG Phoenix 3, an AT&T 4G LTE smartphone
I recently received a bunch of hardware/software documents to scan. I am
only roughly familiar with the systems covered by the docs. I have
encountered a couple situations that I would like guidance on.
1. One document is a software installation manual in a loose leaf binder
with other documents. It has a title page, tables of contents, etc.,
several chapters, and then it gets interesting. It has several appendix
sections (starting at A), an index, then more appendix sections
(starting at A as well), and then another index. The document title and
its font match of the second set of appendix sections and second index
matches the table of contents and chapters. The first set of appendix
sections and index are a little different. The topics covered in the
sets of appendix sections are not the same.
Should I create two different pdfs with different appendix sections or
create a single pdf with both sets?
2. One document is missing the title page and table of contents. Should
the pdf just be what I have or should I create those pages for the pdf?
Thanks,
alan
Since you are all talking COBOL now :
ftp://ftp.dreesen.ch/ICL1501
There is the manual for the early 70?s COBOL implementation for the ICL1501, a small 8K or 16K TTL based personal computer ( TTL based CPU, with 2x 74181 ALU and a 32x8 CRT display)
Not the best of scans, but that alas reflects the material I have.
Some other? doku on the ICL1501 is also included :? an operator guide and tape utilities user guide.
I do have the tape with the COBOL itself, alas no way yet of gettig it on modern hardware.
And if anyone has dokumentation on the ICl1503 or 1501/43, in particular the Diablo drive interface then I sure would like to see it !
Have the kontroller, but no documentation...
Al, as always, feel free to add any and all to bitsavers.

Hi everyone,
Update on the barn-find Sun 3/260 that I have been restoring and was
supposed to exhibit at VCF PNW until the show was cancelled for some odd
reason. The system had been failing to get through self-test because, in
the memory tests, bit 13 was always set, whether intended or not.
I borrowed a couple Sun 501-1102 boards (8M ECC memory for VME) and one
of them passes the self-tests and, if I had a bootable device, the
system is now ready to try that.
But my question here is about Sun 3 memory.
Sun part 501-1102 is described as Sun 3/2xx, 3/4xx, and 4/2xx memory
(The Sun System Handbook does not list it as 3/4xx memory). The memory
board that worked is tagged 501-1102 and was described as memory to go
along with a Sun 3/160 CPU board. I was loaned both boards in case the
problem was the backplane. But the System Handbook does not list that
memory as an option for that CPU.
Does anyone here know whether a 501-1102 memory board be used with a
3/160 CPU?
Does anyone here know whether Sun 3/260 schematics are available
anywhere like the 3/160 and 3/60 ones are? I would like to give
repairing the memory board that came with the 260 a shot, since that is
a better story when I exhibit it and the memory board that I have that
works now is a loaner.
Finally, will a SD2SCSI (configured as 2 Sun0424 drives), Archive 150M
QIC drive, or CD-ROM drive work on the 3/260 if I connect them up to the
SCSI cable for the QIC-24 drive that the system came with?

I have posted here a couple of times because I have a failed VAXmate PSU. I
have just posted a little bit more information here:
https://robs-old-computers.com/2020/03/28/further-analysis-of-the-vaxmate-h7
270-psu-failure/ with some scope traces and a greatly improved schematic.
Although the schematic is likely to have errors still. Unfortunately, a
stray scope probe ground lead blew the fuse so now I have to wait for a new
fuse to arrive before I can continue work.
I would really like to know if all the spiking I am seeing is to be
expected, and any suggestions why it appears to be detecting an overcurrent?
There do not appear to be any shorts on the secondary side, but that could
be wrong of course. I don't know if a genuine short anywhere would cause it
to trip the SCR quite so quickly (within 20ms of the switching transistor
starting to switch).
Any thoughts gratefully received.
Thanks
Rob

I have a DEC VR290 colour monitor for use with VAXstations. It was
working fine when I last powered it on (2-3 years ago), hooked up to a
3100 M76.
It's free to a good home (preferably a home with a VAX), absolutely
collection only. I'm in Nottingham UK. It's too heavy and large to ship
safely.
I have two video cables which are intended for use with it. I think they
are both for VAXstations of some kind, one might be for
DECstation. You've welcome to have them both with the monitor.
Please let me know if you are interested. If in the unlikely event there
is more than one person interested, it'll be mostly whoever picks it up
first but I will prioritise those who actually do have a suitable VAX to
use it with.
Also, if there are any documentation hoarders I have an entire book case
of VAX/VMS manuals (thick red binders). Full list is here, let me know
if you want any. aaronsplace dot co dot uk / dec-manuals.html

Subject: Prime emulator source released on GitHub
From: Jim Wilcoxson <prirun at gmail.com>
Today, with much help from Dennis Boone, I'm releasing the Prime
emulator source code on GitHub for non-commercial use. This is the full
version of the emulator running on Linux and supports:
- all Prime CPU modes: 16S, 32S, 32R, 64R, 64V, 32I
- all Prime models, from the P400 to P6550
- up to 512MB of memory, depending on the Primos rev and CPU
- a system console
- 128 incoming telnet terminal connections
- 8 disk controllers, 8 drives each
- support for all 25 disk drives sold by Prime
- a tape controller, 4 drives, using the .TAP format
- a PNC controller emulating RingNet over TCP/IP
- a bypass for Primos system serial number checks
- Unix utilities to read/write physical tapes & Magsav tapes
Dennis owns the emulator GitHub repo and has also kindly agreed to take
over hosting of the public Prime emulators that have been online since
2008. There are 7 public emulators running in a virtual Prime ring,
allowing both remote terminal sessions (netlink) and remote disk access
via PrimeNet. The Prime emulator on Linux is currently running 45-55
Prime MIPS in 64V mode.
A wide range of Prime software is loaded on the public emulators:
- ftn screaming fast Prime Fortran 66 compiler, written in assembler
- f77 the not-so-screaming but full-featured Fortran '77
- pl1g the PL/I Subset G compiler
- pl1 the full PL/I compiler
- plp the original Prime systems language (like PL/I)
- spl the 2nd generation Prime systems language
- cc the C compiler written by Garth Conby of Pacer Software
- pascal the Pascal compiler
- modula Wirth's successor to Pascal
- dbg Prime's source level debugger rivaling modern debuggers
- pma the Prime assembler
- basicv the Prime BASIC compiler
- cobol the original Prime COBOL compiler
- cbl the Prime COBOL '74 compiler
- emacs the full screen editor still used by many today (me!)
- midas the Prime indexed sequential file software
This week we are working on releasing Prime disk images for all of the
public emulators to make it easy for others to get their own Prime up
and running. For the truly adventurous who want to bootstrap their own
Prime system, there are links in the emulator readme to Prime tape
images at Bitsavers and to a large library of Prime manuals.
I learned more about operating systems, compilers, concurrency, and
other systems programming topics by reading Prime source code, making
changes to Primos, and fiddling with Prime hardware, than I did from all
of my college degree work. I loved Prime computers, Prime software,
Prime hardware, and the Prime Computer company, and am grateful to all
of the former Prime engineers that provided this robust and interesting
hardware and software platform.
I hope you enjoy it too! https://github.com/prirun

"Ouch. Looks like that core took a serious hit."
Yep it did. We ran the microscope into it at the lab. Ouch. Someone had
asked for a picture of core memory without the cover so I thought it
would do.
Prime Fans,
I just noticed on comp.sys.prime that I missed a couple of sample system
releases. I have a process set up to dump messages from some news groups
into my IMAP server for easy reading with my mail client, but I don't have
anything set up to easily reply via the news groups. Does anyone know
what's new in the recent sample system releases?

What's the definition of a legacy system? One that works!
Errare humanum est, ignoscere caninum.
The virus-world we are living in has seen Internet usage dramatically
increase world-wide. Thanks to pioneers like Cerf, Kahn, Crocker and
Kleinrock, sounds like a law firm, paved the way for the packet-switch
system Bell & others fought to prevent. I recall the early days of
computing, classic, retro or otherwise defined, that was slow, but had to
do more than now, as the hardware wasn?t so great or more accurately small
and fast. Their were machines that allowed us to communicate at 300 baud
and I was happy!
Stay safe. Happy computing and communicating.

Trivia: for a while in the mid-to-late 1990s, a Google search for "computer
porn" had as the number one result one of my web pages, of that title,
containing images of computers with covers removed. I could see from the
server log that the search was fairly popular, but nevertheless I believe
that most of the people doing the search were not satisfied with the result.

**************************************
This machine acts oddly. After powering it off, you usually can't power it
back on again for about 30 seconds or so, it just seems to ignore the power
switch. Similarly, if it has been switched off at the front power switch, it
will switch itself on after maybe a minute of two of being switched off. In
all other respects the machine seems fine. I have not opened up the PSU at
all, just wondering if anyone has ever seen this and might know what the
problem is?
Thanks
Rob
Hi,
I am sure this question has come up before, but can anyone advise an OS/8
change I can run to avoid the following issue (below)? I am unsure if I
need to fix my simh INI file or make more space for the program from the
OS/8 dot prompt, or FORTRAN * prompt.
Running pidp-8i (simh PDP 8i kit)
I load OS/8 and initiate the command from the dot prompt:
. FRTS
..dumps me to the * prompt ...
*RKB0:ADVENT.LD [return]
* [esc]
rather than loading ADVENTURE I get the following result:
D.F. TOO BIG INIT 0000
MAIN 1740
.
(..andkicks me back to the dot prompt).
the INI is the default
reset
set cpu 32k
set cpu noidle
att rk0 ../imagefiles/os8/advent.rk05
boot rk0
what changes are needed? I searched around, I don't quite understand how
to load an LD file in OS/8 to debug the error. It may be I have the wrong
RK05 disk, but I'd really like to understand what this error means if
anyone knows. My physical RK05 disk loads ADVENT as an SV file, I don't
need the extra steps.
Thanks

Thanks for the confirmation that that info is sufficient to produce a working

Greetings folks
The past few years I?ve become fairly focused on a particular old 1999/2000 ww2 fps computer game. Of course playing it but I?m also on the development team for the game (EA has given up on it, but we still put out new releases, maps, patches, etc.). As a result of that, I pretty much live on Discord text/audio chat these days. If you send me an email I will eventually see it and may even respond heh. But if you send me anything on Discord I?m going to see it immediately. If any of you are on discord, I am ?Todesengel#9624?. Feel free to add me as a friend and that way you can get me usually immediately. I am not leaving the hobby, nor am I saying not to email me at the usual address. But a lot of you do talk to me semi-frequently and I?m just saying discord will get to me far quicker.
In addition, mostly as an exercise to see how to do it, I set up a ClassicCMP discord server. That Discord server is NOT meant to replace this list, nor should it be taken to signal any less commitment on my part to keeping this list running. They are fundamentally different things; Discord is great for real time text chat back and forth. There are also audio and video channels if people want to use that to talk verbally or via video. To get on that server, here is a semi-permanent invite: https://discord.gg/U8Skw5g Joining the server gets you to all the other folks who may join the classiccmp discord, not just me. Of course, that could be zero ? Like I said, I just did it as an exercise, and discord is how some of my family and friends stay in touch. But it is there if peeps want to use it.

I'm working with a batch of tapes that includes several IBM Series 500 7
track reels. If you look at the back of the reel, there's no customary
thumb recess for removing the write ring. Rather, the reels have a
small red plastic peg that extends through to the front of the reel.
Is this for ejecting the write ring (I haven't tried)?
In any case it's a bit annoying because it grazes the edge of the ring
sensing finger, making a little "click" every time the reel makes a
complete revolution.

Thank you Richard, yes if you're willing to check your inventory of ARCnet cards I may find something useful. ARCnet boards are pretty much all the same, but this particular one I'm hunting for from Intercontinental Micro is compatible with a special boot ROM I have that promises to unlock wonders unknown to the world since 1987. Maybe I exaggerate a little bit, but I do appreciate you checking.

Okay, I've only ever been a user, back in high school, of HP 2000F TSB
system but wanted to play with it again and learn more about the system.
I've been able set up Simh with 2000F TSB and everything is working
fine. Using the latest release I can find out there, HP2100 release 29.
Now I'd like to be able to install some of the Contributed Software
Library but despite reading the various TSB manuals and Simh doc, I've
been unable to actually get anything loaded.
Can anyone with experience with this lend me a hand, some tutorial or
point the way to some instructions I may have missed?
Thanks in advance.

I'm on a quest to find an ISA ARCnet board from Intercontinental Micro. It's called the LANPC and would be very useful to me since I have the special software to run it. Here's a picture of what it looks like.
