You're fine, as long as your 11/73 has less than 248 kbytes in it.
The RLV11 won't DMA any higher than 18-bits; if you've got 256kbytes
or more of RAM, you want a RLV21.

Oh, yes, the backplane: You need two adjacent slots with the "CD"

No, the RLV11's won't, but a RL11 will.

Ok, so the subject is a bit provocative, actually the question isn't that bad.
Are there backends for the GCC compiler tools for the 'classic' computers
out there? I'm particularly interested in a PDP-11 back end at the moment
as it seems that I could easily port uC/OS II to the 11/23 and have
something useful without forking over the RT11 dough.
In lieu of that, if I compile programs using RT11 under Supnik's emulator
can I run them on a "real" 11 legally?

I can't see that running software you developed yourself would be
illegal to run on real hardware regardless of where it was built.

And i forgot, what type of monitor you have, but it should have at least
1280x1024 at some graphics options. Sometimes you can change that to
1024x860 via a switch on the graphics option.

The PDP-11 backend for GCC is a decade out-of-date with the rest of
the changes in the compiler. Updating it ought to be straightforward,
but nobody's stepped up to do it. Alternatively, you can use the PDP-11
backend with the matching version of the GCC front end, but I don't
see any decade-old versions of the front end at the traditional GNU
distribution sites.
You also have to keep in mind that GCC doesn't come with a PDP-11 C
run-time library. Not a problem if you're writing an OS from scratch and will
be writing all the libraries too.
Too bad you're giving up on RT-11 so quickly - there's several hundred
megabytes of freely-distributable code available for it in the DECUS
collections.
>In lieu of that, if I compile programs using RT11 under Supnik's emulator
>can I run them on a "real" 11 legally?
I don't see why not - especially if you're using (for example) the free
PDP-11 DECUS C compiler - as long as you anything you use the code for would
come under "hobbyist".
The DECUS C compiler is quite capable, and many major packages have
been written in it.

There is a nearly hidden switch between the leds and the MMJ connector,

Also DEC spins the drives up after the boot starts not at powerup.
The monitor if there is no disks(at all) should display a countdown as
it does self test. The monitor can be interacted with for diagnostic

Does anybody here know of an old bicycle mailing list/message board?
Does anyone here use or have old bicycles? The reason why I ask is that I
found an old English bike, several decades old, and would like to know
when it was produced, etc. It's certainly a lovely bike, black with gold
trim, in perfect condition after I washed off the dust.
My two functional questions:
1) Can I use WD-40 on non-moving parts to keep them from rusting?
2) The thing has one of those 3-speed in-hub gear shifters but the cable
and handle are missing. Therefore, the little chain is retracted into the
hub. Is it in 1st speed or 3rd speed? Does anyone have any extra 3-speed
switch handles :)

Does anyone have any docs on the decitek paper tape reader?
Full docs would be fantastic, but initially just two items:
1) The unit appears to be set for 220v. Is there some simple strappings to
change it to 110V?
2) I have no power cable for the unit, and it uses a (to me anyways) rather
unique power cable. Any ideas where I might find a power cable (Digikey,
etc?)?
Thanks in advance!

I have an old Nicolett NPC-764, which is CP/M machine (8085 based) with
built in Logic Analyzer hardware (its main function). The logic analyzer
software was stored in 48K of ROM, and you could boot CP/M from there. Its
a "luggable" computer (which means that they put a handle on it and bolted
down all the boards ;-). One thing I do not have is any 5 1/4" floppy disks
for it. Because of this, I can't boot CP/M and I don't have any of the
software that came with the unit that assist in using some of the logic
analyzer's abilities. Do have any idea on how I could get some of this
software? Nicolet hasn't been any help.

I take extra care with my prototypes because they not only prove the
concept, but they have to serve as a development tool. In reality,
wire-wrapped circuits are more likely to survive mishandling than a PCB
would be. Whereas you could break a pin or a wire, that's normally quite
apparent to visual inspection. I've got a whole paper-box full of
perfect-looking PCB's which don't work because of some intermittent open or
short due to an overetched or overstressed circuit board.
Where space was a problem, I've been known (rarely) to ship prototypes which
were hand-wired with point-to-point soldered #30 wire. This is much like
wire-wrap, except it require much greater care to cut the wires to just the
right length and strip just the right amount of insulation. It makes for
plenty of wasted wire.
BTW, TechAmerica now sells sheets of 0.100" matrix wire-wrap card with
low-impeance ground/Vcc plane on top/bottom, similar to what I used to build
into my wire-wrap boards. This is really handy, because you can isolate one
section of ground plane from another with a Dremel tool and connect them
with a bypassed ferrite bead or low-value resistor. This makes for
realtively quite regions if you take sufficient pains.

Howdy;
Several years ago while I was at UW I promised myself that one day I'd get
a VAX and learn how to use VMS. That day came yesterday, when a VAXstation
3100m76 showed up on my doorstep.
So in the immortal words of Zane, "I can't get it to boot." (:
I realise I may be making an entirely faulty set of assumptions about what
I'm doing so here's where I'm at.
I received also an LK201 keyboard, the wondrous "hockey puck" mouse, and
the video cable (15 pin D-sub on one end, 3 BNC plus what look to be
keyboard and mouse connectors). The machine supposedly has SPX graphics.
I connected the video cable to the appropriate port on the rear of the
VAX, and plugged the keyboard and mouse into the connectors on the cable,
and the 3 BNC to a NEC 5fge, which supports composite sync-on-green and
I'm fairly sure should sync up to whatever the VAX puts out.
Switched the machine on, and waited. And waited. Nothing. No lights on the
keyboard, nothing on the display. The LED status whatsis at the rear
wibbled around a bit but I didn't pay close attention to what it was
doing. The disks never spun up.
I tried again with the keyboard and mouse plugged into the connectors on
the back of the machine, and got keyboard lights, but aside from that had
the same luck as before.
What should I be looking at first? I'll try to borrow from work a cable I
can use to connect a serial terminal to the box to see if anything useful
happens then.

Hi r,
Tell us the signature of the LED's.
Probably, something is wrong with your motherboard, memory, graphics ...
Another idea is to plug in a terminal in the printer port. probably you get
a message there.And don't forget to put the little switch "up" that is left
to the 8 LEDs. If it is already "up" you have the terminal as the console
already, so you don't get anything on the Monitor.
You told that you have a Lk201 ? Which of the LEDs are on ?
(they displaying some errors from the box too)
hope it helps,
cheers,

I have found that the 99MP is good as a starting base and then add the rest.
In the toolbox that I use every day I think there is every 99 series tool
that is avail. There are also some that they don't make anymore. Also you
need to check out the security bit sets that Jensen offers. They have the
most complete set I have found.

My boss has come up with a good use for all my old toys!
We're an ISP here, and I play BOFH. So, we're moving to a new building,
and all the customers are wanting to see our internet toys when they
sign up. So, the new machine room is being constructed as follows:
1. It'a a large room, raised flooring, and it has an observation
window. The idiots can look thru the window, but not come in
the door.
2. The room is also decently air-conditioned. It'll (obviously!)
have fast 'net access.
Meaning:
3. We aim to get our hands on all the boxes we can with flashing lights
or interesting buttons on the panels. These will be visible from
the window. All the real gear will be on the other side of the room.
Basically, this means all my boxen get a fast 'net wire, and a nice
room to live in. All they need to be able to do is look complicated and/or
impressive. Is this sort of thing legal? Sounds too good to be true to me...

I thought about, why i haven't found this before.
Sorry, no offense, but "its the name".
( seeing the "RESCUE" i saw already one of this SAR helicopters around my
head ;-))
I just was on your site, and this is probably exactly what i tried to do.
I would only suggest, to put the "collector" somewhere in the name.
thanks a lot for your work,

Hi Allison:
I have the schematic in front of me, mechanical drawing too. It's on my web
site if you _really_ need it after this, or send me your fax number and
I'll get it to you that way.
Looking at the mechanical drawing, if you look at the rear of the 8/f, with
the H740 installed, the bridge rectifier is at the top, right hand side of
the supply, above the large heat sink fins, to the right of two large
transistors.
Ascii art for pin orientation:

The rectifier is labelled only "NSS3514", no ratings indicated in the

I recently obtained an old Nicolett NPC-764, which is a CP/M machine (8085
based) with a built in Logic Analyzer, with software for the logic analyzer
built into ROM. Its a "luggable" computer (which means that they put a
handle on it and bolted down all the boards ;-).
One thing I do not have is any 5 1/4" floppy disks for it. Therefore I
can't boot CP/M and I don't have any of the software that came with the unit
to assist in using the logic analyzer. Do have any idea on how I could get
some of this software? Nicolet hasn't been any help.
Thanks!
Hi. I'm new to the list and this is my first posting. I am looking for
PL/M cross compiler that Intel produced for the 8008 CPU. I have the Intel
manual, but no source or object for the language compiler, which was written
in Fortran by Gary Kildall when he worked for Intel back in ~1973. I have
source for an 8080 version of PL/M from Intel which went into the public
domain at some time, but I do not believe that it will produce 8008 code
(that ability is not mentioned in the documentation). Any help or
information on this would be appreciated.
Also, a macro assembler or a basic interpreter would also be appreciated!
Anything would be better than hand assembling and jamming in bytes via
switches.
Thanks,
John

This strategy is pretty popular with analog work being tried for the first
time. I prefer to wire-wrap my digital stuff, and I've shown that wire-wrap
between digital and analog circuitry can be mde to work as well. I prefer
my prototypes to be really rugged unless there's a specific reason why one
can't be, and I'm always afraid to play with those "spiderweb-technology"
circuits, so once built, they never get any improvement from me.
Now, I've learned a few tricks from those analog weenies who use this kind
of stuff all the time. I'll certainly never forget watching one guy track
down a 4MHz clock from a processor getting into the analog section of his
circuit by using a divider with points sharp enough to penetrate the solder
mask and a spectrum analyzer. He found the section of ground plane which
needed bypass, then fixed it with a couple of capacitors bypassing the
unwanted signal to just the right place. No mean trick if you ask me.

The "traditional" DEC way of dealing with this is to have pockets on all
the spines and put cardboard identifiers in each one indicating which
volume it is. If you go to a well-stocked office supply store, you'll
find similar sized pockets that are self adhesive and which you can
stick to the spines of your new manuals, and them label everything
appropriately.
All the way back to white, eh? My old TOPS-20 manual set (from mid-to-
late-70's) is in white binders...

Incidentally, there are several places on the net where the OpenVMS
documentation is browsable. For starters, you can go to
http://www.openvms.digital.com/ and click on "Documentation". It
looks like the Cluster manuals and DECnet manuals are there. Of
course, electronic docs are not nearly as satisfying as a "grey wall" (or,
as it seems to be now, white), but it can come in handy in a pinch.

The "Classic Computer Rescue Squad" web page lists people's location,
classic computer interests, and contact info. If you aren't on it,
you are missing out. And if you want to find nearby classic computer
geeks, this is the obvious spot for one-stop-shopping.
E-mail addresses on it are mangled to make it more difficult for
spammers (though I have an idea for a better anti-spam measure), and
pretty much all the decisions about what info to list are made by
the Rescue Squad volunteers themselves. I've even been pretty good
about maintaining it. Requests usually get handled in less than 24
hours.

Hello, I recently aquired an Osbourne Model I luggable.. I have system
disks for it and I can't wait to fire it up.. unfortunately it has a bad
power switch (a little flaky; works occasionally, usually not), which is
not big deal as I can change that out.. the problem is when I was working
on the panel that has the wires attached (wrapped around those posts) I
accidentally ripped them all off (grr).. does anyone have a pinout of
which colored wires go to which pin?
thanks,
Kevin

Yup. He's the one. Quite the god of telecom, judging by the level
of detail in his manuals, and the power and reliability of Pro-YAM.
My POTS dial-up has diminished ever since I got a T-1, but Pro-YAM's

Exactly. Those on the collectors list would not necessarily be willing to
go to extent of arranging transport etc. For example, altho I have done rescues
of old equipment, I don't even have a vehicle to do so and as with most of us
very limited and rapidly dwindling storage space.
It just makes it easier to find collectors in your locale who might have
similiar interests.
It's a good start but please keep the names coming. Only those collectors who
wish to be included on the list and who send the data will be listed.

Not quite . . . those stepping relays had quite a bit more energy as they
had to move something more massive than the little relay contacts. It's
more like what the room full of stepping relays sounded like from down the

For quite some time, when DEC decides that they fired/laid off/re-assigned
the personnel that knew how to do the job, they've been going to outside
sources (such as Mentec), and these outside sources often been hiring
outside consultants. The markup after going through this chain of
"resellers" is truly amazing; in some cases the customer has ended up
paying $10K just for installation of a RSX11M+-with-TCPIP upgrade, for
example.

As for RT-11, you're right... because it is handled by Mentec now. But
for VMS... don't be so sure... At work yesterday I saw a box of VMS
manuals which was being distributed to the VMS support group... they
clearly had "Compaq OpenVMS" on them...
