When I received my model 33 it came with a UCC82 Call Control Unit as an
extra in the deal.

/CGS_0127.jpg (Photo of the CCU)
It doesn't seem to do much on its own (makes the teletype print null
characters uncontrollably when you plug the system in) and I can't find any
information on what it did however just looking at it and a small note from
google says it was used for putting a phone line on and off the hook and
dialing. The row of buttons at the bottom controlled a Bell 101 or 103
DataPhone which you hid away in the stand.
I've been searching up info on the 101 and I can't find a whole lot of
anything short of it was one of the first modems, it was 110 baud and it had
a D-sub 25 port that you connected it a computer/terminal with. They also
seem to be about impossible to find. I have modems that cat run at 110 baud
however god knows if the D-sub serial port on the back of them are the same
and even if they were I have no idea how it would of connected to the
teletype. Does anybody have more information?
Hello.
Maybe stupid question but I'm a newby of VMS.
I have a VS2000 with a Micropolis RD53 inside.
I recently repaired the hard disk, and from some tests it seems to have
no errors, so its content is safe.
I tried to boot the machine from it, and it turns to contain a
standalone backup.
I would try to list the content of the disk, but from manuals I
understand I would need to know the file names.
How to identify the content of this disk?
Thanks

I am looking for a working TK-50 drive. Mine is giving me a "not ready" on
the system. Is there any documentation out there on these tape drives? Is
there a way to emulate these?
Hutch
Has anyone come across one of these before and more importantly (to me!) has anyone any data sheets or a manual on the tape drive.
The drive has a Toshiba label on it saying "Cartridge Tape Drive MTH 0551 F001 Model No. CD-1000C" and has a direct drive capstan.
It looks like a 1/2" Cartridge Drive and it was used on the Data General Desktop Generation E6270 drive. I can find no mention of it on the internet so far!
Thanks, Mark
It's running on a small server out in my garage, connected to the internet thru a wireless link.
Usually it is on 24/7 but sometimes the cable internet will go down for maintenance, esp in the middle of the night PDT.

Your first link is broken. ;)
I thought the same thing until two things happened:
1: I got ahold of two Widgets and found that no, they are NOT similar to any
other HDA assembly out there unlike that found in the Profile which uses the
ST506 and ST412 assemblies from Seagate.
2: Digging through Apple's patents there's paperwork outlining the design of
the drive which was voice coil and not stepper motor MFM like everyone else.
It /might/ of been assembled in-house (there's no markings saying another
factory did it so they might of actually run a clean room for HDA assembly)
but it was obvious they designed the drive.

Hi! There are some XT-IDE V2 PCBs available if anyone would like some.
They will cost the same as before ($12 each). However due to unforeseen
extreme price increases in shipping by USPS I am forced to change shipping
costs.
Shipping in the US will be $3 for a single PCB and $2 for each additional
PCB. Shipping internationally will be $10 for a single PCB and $3 for each
additional PCB. This is for the bare basics USPS first class postage with
no tracking or insurance. The builder assumes all risk of delivery as per
usual arrangement.
I apologize for the large price increase on shipping but this is out of my
hands. The USPS is in dire financial trouble and is raising prices on
shipping. It affects us all and is most unfortunate. These boards are
provided "at cost" so there is no margin to absorb any shipping price
increases. I have to pass them along.
If you would like one or more XT-IDE V2 PCBs please send a PayPal to
LYNCHAJ at YAHOO.COMhttp://www.vintage-computer.com/vcforum/showwiki.php?title=XTIDE+Rev2
There are about 10 XT-IDE V2 PCBs left.
Thanks and have a nice day!

I need to get a microphone for my podcast, and I've been advised that the Blue Yeti is what I need. So to come up with the $130 or so, I've got a lot of five Toshiba 610CT laptops for sale.
Or trade if you have that mic.
The lot is five laptops, four work, one does not. They are Pentium 90s, with 40 MB of RAM. Couple of different drive sizes, 1.2 GB, 800 MB, etc.
Lot comes with one docking station, couple external floppy drives, an external CD-ROM, 7 or 8 power bricks, a couple of VGA adapters. Some spare parts like keyboards and keycaps and spare RAMs. Also included are PCMCIA modems and Ethernet combo cards.
If anyone is interested I can give more detail.

I know of only one example of a debugger which supports
a Program Counter History Log.
I am in the process of adding a Program Counter History Log
to the System Debugger in RT-11 on a PDP-11. I would
appreciate a few suggestions from anyone who has any
experience with a debugger program which supports
Program Counter History Logging.
For users who are not familiar with PDP-11 hardware,
the primary interface is a serial terminal, usually with
9600 baud these days (don't laugh - I first started on
a PDP-11 around 1975 over a 300 baud modem), with
a screen of 24 lines by 80 columns. There are a probably
a VERY, VERY few systems which use VT420 terminals
which can support 48 lines, but which are probably rarely,
if ever used with other than 24 lines by 80 columns. From
my point of view, the primary considerations are the lack
of both speed (9600 baud takes seconds to fill a full screen)
and available screen space to display more than about 200
addresses from the History Log Buffer (at 10 addresses
per line). While I normally use the Ersatz-11 Emulator for
the PDP-11 which provides me the possibility of using
screens of 50 lines, I suspect that I am presently the ONLY
person to interact with RT-11 using a screen of this many
lines, let alone the speed of the screen which is so fast that
the time between SCROLL and NOSCROLL is usually
a dozen lines of output to the screen. At 9600 baud, the
SCROLL vs NOSCROLL time delay is only a few
dozen characters at most, certainly less than one line
of output to the screen in almost all cases.
The only experience I have with a debugger which has a
History Log is with a 64 word buffer of addresses for
the 64 immediately previous instructions. While this is
often sufficient to at least pinpoint the general location of
where the program stopped, it was often insufficient to
locate where the problem started.
For those who have direct PDP-11 experience, the
following information might also be useful. At present,
there are two buffers which can be displayed:
(a) A buffer with 40 of the last interrupt entries to SD:
which are composed of 5 words each:
- Program Counter Address from the Stack
- Program Status Word from the Stack
- Word (instruction?) at that Address
- Word (instruction?) at the Previous Address
- Control Word which is used by SD: (PROSNG)
(b) A buffer with the last 1000 Addresses of the last
1000 instructions that have been executed
The current logic in the code to save each instruction
address in the 1000 word buffer ONCE and ONLY
once uses all five of the above values.
There seems no point in displaying all 1000 addresses
since only about 200 can stay on the screen and it takes
too long in any case. However, just how useful are the
past 1000 addresses as an aid in debugging? Since it
takes no additional time for a larger circular buffer over
a smaller circular buffer (in fact maybe a larger buffer
is insignificantly faster) and there is memory available,
I opted for the largest buffer that was reasonable
The other buffer with the 5 word entries entries for
the last 40 interrupts will be used when there are any
questions about the exact details of any interrupt with
respect to a user having set a Breakpoint or any other
logic errors in the debugger in general and specifically
when adding addresses to the 1000 word history log.
NOW finally, here are my questions.
Are there any suggestions as to how many previous
instructions are needed to usually be helpful to have a
log for when a program has a problem? Also, would
it be useful to have the first word (two bytes) of the
instruction as well as the address in order to identify
the actual instruction or is the address almost always
sufficient? On the PDP-11 with instructions being
1, 2 or 3 words, it is totally unlikely that having the
addresses of the previous instructions would ever
allow a user to confuse which code was previously
executed unless two variants of almost identical code
had been purposely constructed so as to confuse the
user. This could occur when two overlays use the
same addresses to execute that code, but it is almost
impossible to happen by chance and even it it did,
an extra NOP could simply shift the code for one
of the variants so as to avoid the confusion.

Jerome,
hopefully you'll get much better-qualified answers than mine;
I have little to no experience programming assembly or PDP-11. That
said, I can think of a few possible answers:
1) enough instructions that any timing-critical loop will be captured
when an external interrupt dropping into the debugger is generated.
This might be relatively short - 200 instructions or so? User
(not necessarily programmer?) would set up and start a long
calculation (mandelbrot set, whatever) and then hit "break", and be
able to look back far enough to verify that the correct sequence of
instructions is repeating over and over.
For actual number, maybe look at the longest loop in RT-11
that repeats many times successively?
2) enough instructions that any timing-critical *subroutine" will be
captured when dropping into the debugger.
This would be a *lot* more, depending on application. In this
case, the programmer would add a break point to the code right after
the timing-critical routine (disk access, real-time control interrupt
service routine, whatever) and then look back at the buffer to verify
that the whole routine took the correct execution path. For disk
access, that might be a *lot* of loops, though, so maybe you are only
capable of writing a buffer to hold the last few iterations?
For actual number, look at the longest single executable code
unit in RT-11?
3) Configurable depth, configured at launch time for debugger
Programmer gets to make the trade between debugger buffer
depth and available memory for his program.
Not sure any of this is helpful, and you probably have
thought of it anyway.

After a couple of evenings spent tracking down a core memory problem, I
now have myPDP-8/L running (haven't yettested everything but it's been
looking good so far.)
There are four bulbs out on the front panel which I have some spares
for, but while going through the replacement I noticed that only one
("CA") of the six "Major States"bulbs is actually installed (therearen't
even sockets present for the other 5, doesn't look like they were ever
present). Is this typicalfor the 8/L?
I may install sockets for the other 5, because I'm pretty sure that more
lights = better computer...

As some of you know, I have two smaller children, ages six and seven. I
decided it was family movie night and busted out a copy of "Flight of the
Navigator." ... this is a Disney-produced sci-fi flick from 1986 and
includes some interesting CGI (from 1984-1985 if you think about it.)
So with the kids entrenched by the plot, I broke out the google and began
to search and try to find out "how did they do the cgi for Flight of the
Navigator?"
I found the following, which answered my question.

I am using a DEQNA and booting off SIMH running VMS 5.4. This has worked
fine for me multiple times before without issue. I have just tested both a
VAX 4000-200 and a MicroVAX 2000 (over thinwire, very slow to boot) and they
both boot fine, so I don't think there is a problem with the boot node or
the network.
I have tried replacing the cabinet kit (this is the same machine where I
have been having the cabinet kit problems), the AUI converter, the patch
cable, the DEQNA with another DEQNA and also with a DELQA. The result is
always the same.
I am not sure what the problem might be. I suppose it could still be
something at the network level. It might perhaps be the CPU board, but if it
gets that far into the boot sequence (already prompted for date and time)
this seems unlikely.
Any suggestions?

Rob

It by default will return 403 to certain geographic ranges of IP addresses (China, Russia, Some Europe, South America, etc). I had way too many intrusion attempts from those areas, so they are by default blocked.
If however you try and access an actual existing web page on the site (rather than nonexistent PHP CGI stuff) it will put your IP into the allowlist, and the next time apache restarts (typically within an hour or so of the access) you can try again and the page will load.

I have a DEQNA cabinet kit that does not work. I know this because if I
replace it with another one the activity light on the switch works and I am
able to see MOP requests coming from the machine to my boot node, with the
faulty one none of this happens.
Now, I have tested the fuse and I have tested the connectivity of every wire
>from the internal connector that connects to the DEQNA board (also tried
with a DELQA by the way) to the AUI connector on the outside of the cabinet
kit. Everything seems to be OK. But it doesn't work. I have tried "jiggling"
the wires a bit while testing the continuity of the wires, but it still
seems OK.
What other failures could there be?

Evening all,
I?ve been thinking (I don?t actually have a secureboot-capable device nor have I read the spec) about one would theoretically circumvent it.
I was initially thinking of it in terms of how TSX as booted on the PDP-11 (starting at RT-11, loading TSX as ash application and having it replace RT-11). That approach has some flaws, however:
1). In the case of WinRT, user mode apps wouldn?t have the privileges to replace WinRT?s memory.
2). Kernel modules providing a shim would need to be signed else they wouldn?t load.
3). You couldn?t modify a driver without the checksum matching. Which brings me to this: Does SecureBoot actually check if the checksum matches, or just the public and private key?
Alternatively, how securely is the key stored? Would it be possible to retrieve the key from memory? If that?s doable, it would be easier to implement this.
Are there any steps in the modern NT boot procedure I?m forgetting that would let you inject a ?boot loader? to ?jump? to either windows or Another OS that would circumvent SecureBoot?
Thoughts/comments greatly appreciated!.

Hi All
As I can't get any response from HP, I've decided to give this group a
try... With a group of a system programmers, we're working on free, open
source 3k emulator, based on QEMU (and it's binary translator), with the
goal to get a fully functioning rp7400/N4K environment. As for now, we have
it working with HP-UX 11i, but our main goal is to get MPE/iX up and
running on it... So, my question is - is someone on this group able to
provide us with a MPE/iX installation media images? I know it's a gray
land, but as I can't get any response from HP (even after they announced
their HP3k simulator programme), I'm willing to risk and try to run our
simulator with 'unauthorized' copy of the OS, just to check if it's
working...
Thank you for your help,

John and I have just completed a new S-100 board and are now taking
reservations for the first batch of manufactured PCBs.
It is the S-100 Parallel IO board which provides four input parallel ports,
four output parallel ports, and a PC compatible Centronics port.
It has debugging LEDs and other features to help get your S-100 system
working in top shape.
The board is designed to be reliable and easy to assemble.? The schematic
and PCB layout files are on the N8VEM wiki here

The PCBs will be $20 each as per the usual arrangement.? Shipping in the US
is $3 for a single PCB and $2 for each additional PCB.? Shipping
internationally is $10 for a single PCB and $3 for each additional PCB.?
This is for the bare basics USPS first class postage with no tracking or
insurance.? The builder assumes all risk of delivery as per usual
arrangement.
Please send a PayPal to LYNCHAJ at YAHOO.COM with ?S-100 Parallel IO board? to
reserve your board.? I will place the PCB manufacturing order as soon as I
get to 20 units and will get a few extras for those who come later.
Thanks and have a nice day!

Sorry for the spam to the list, but for the folks that were going to come
by this weekend to buy/pick up stuff I have to reschedule...there was a
sudden death in the family and I have other things to attend to.

Bill Gates introduces OS/2 in 1987. But look at the screenshots at
2:50 when they talk about Sun's new RISC processors. :?)

I'm looking for a S3, Diamond Multimedia or SonicBlue FireGL2, FireGL3
or FireGL4 AGP video card. A bounty is available.
NOTE: It CANNOT be ATI (including those OEMed from ATI labeled IBM, HP
or Dell).
Regards,
Lyle

All the rotary encoders on HP instruments from the late '70s thru the late '80s used +5V, grain-of-wheat bulbs. I have yet to see a led used in any of the 15 - 20 encoders that I've repaired to date.

All the other stuff given away has been claimed, often within minutes.
Sorry if I don't reply to everyone, but if you don't hear from me, that
means that someone else has claimed it.
Evening all,
I recently parted out an old electric organ which had a too-far-gone electrical system for me to repair it. I now have some spare micro controllers and misc. ICs I have no idea what to do with.
Anyone need an Intel 8035 or have any ideas what I could do with one? I?d know what I?d do if ti were z80 compatible, but it unfortunately is no.
