Hello!
Problem, this computer suffered an attack of typical Microsoft issues
regarding its OS and required an installation of itself back about a
month earlier. I ended up loosing my bookmarks. One of them was for
the US based offices for the users group for VMS. As I recall and en
examination of the form used to create the licensing string for VMS it
requires that name. It also needs the member number from the group. I
recall creating one for a kit that Sampsa has someplace last year, but
I never managed to launch the Alpha emulator on any of the approved
operating systems for it.
Now I'm ready to try again with the VMS kit I have here someplace (it
presupposes that I can find it, but I do know that the image can be
downloaded...) and running on the SIMH Vax setup using the
instructions on the site that the SIMH one is linked to.

Huh? That's a J-11 based board, and I'm pretty sure the
CIS option for the J-11, while planned, was never actually
shipped. It would have been two additional chip carriers on
the bottom side of the big white
J11 multi-carrier chip.
The only ROMs on a KDJ11-Bx board contain the boot/diag
code, not microcode, and conversely, the only microcode on a
KDJ11-Bx (or any J11-based board for that matter) is in the
microcode ROM, which is a part of the "control" chip, which
is one the two chips on the J11 multi-chip carrier itself.
No microaddress lines or any other internal state machine
stuff is brought out to the pins of a J11.
(sorry!)
You CAN, however, get a CIS option (if you can find it!)
for your 11/23! I too would love to mess with CIS a bit;
I've never done so. I have two CIS option board sets for my
11/44s but have not yet installed them.

The node PLUTO:: is a PDP-11/23+ with both CIS and FPU running RSTS/E.
You can run an emulated one using SimH if you do not have the physical
hardware. I have both running. You would be hard pressed to know if
the system running (and connected to HECnet) was the real one or not!
COBOL was the reason that CIS was designed for the 11/23+. Other
languages can also make use of it. One that comes to mind is DIBOL.

Not unless someone could dig up the details. If it *is* just a PROM, even if it's an oddball bipolar model with different interface specs, it should be easy to reproduce that with a small FPGA. Any reasonable modern FPGA is way faster than a 1980s era bipolar ROM, so modeling the interface timing should be easy. And level conversions should be doable.
So a sort of daughterboard? That's a good idea.
I'm pretty sure the F11's manuals are out there, but I haven't gone
digging for them. From that, and possibly even just from the KDF11-Bx
schematics, one should be able to glean the important parts of how to
interface to the microinstruction and microaddress buses.
Then all we'd need is a copy of the actual code.

I don't know if Dibol uses it. I do know that the RSTS kernel does for memcpy.

Yep, the information there is wrong. No CIS for the J11. The only CPUs that ever got the CIS was the F11 and the 11/44.
(Now I'm sure someone is going to point out the 11/74 CIS option, but it was never sold, even though I've heard that at least one prototype was done.)
Okay, I'll check the 23Plus when I get home. Might get lucky there and
be able to have a play with it there. On topic, seems to work in the
quick test (sadly had work to do at home) I did last night which was a
couple of memory fills so that's promising.
Right. So no CIS for 83/94, but there is for 23Plus.
Right.
Thanks for the straightening out :)

This CIS option is not a PROM, even though it might sound like that.
It's more like a co-processor.
If the CIS options is installed, you can easily see that,
physically, by
the large chips next to the CPU. If it's not there, you have some

Oh! And Darn! I should have checked proper. The M8190 is indeed the

I thought you were talking about the 11/23+ and 11/24 in my first

Not yet, but keep after me about it and I will photograph the boards.
Really wondering about
the /23Plus. If the option for it is just PROM's that should be pretty
easy to reproduce.
It won't be at all easy to reproduce. They are MICROMs. The F11 CIS
option is one of those multi-chip carriers, but for CIS it is two
40-pin-DIPs wide, and contains six MICROM chips. These are bipolar
mask-programmed ROMs with an (I think?) undocumented interface. I would
be more than a little surprised if anyway, even someone of technical
means, could reproduce that.
Since you have an 11/23+, you are in luck; that has one more 40-pin
socket than the dual-width 11/23 CPU board. It can accommodate both the
CIS MICROM option and the floating point MICROM option. On the
dual-width 11/23 boards, you have to remove the floating point MICROM.
You could remove the MMU chip to make room for the double-wide CIS
chip carrier, but that'd be pointless because, if memory serves, the
floating point registers reside within the MMU chip.
The 11/24 has yet one more socket, so it has no such limitations.

That Doctor Who book I mentioned has them running roughshod through the
early Internet, and largely colliding with UNIX on PDP11s, (I believe they
were supposed to be PDP11s, but they were not described, or named.) although
the author stuck an Eclipse in someone's home also running the same.
Interestingly enough I do know that UNIX came to DG rather late in life,
much later then the book took place. And even after the Eclipse that's
described there was first turned on.

I have no problems calling -11M a redo of -11D. As far as I know, it was

DEC. But that is just what I gathered from reading various sources over
the years... I could very well be wrong.
-11M was entirely done at DEC. -11D was brought finished from DuPont,
and was AFAIK written single-handedly by Cutler. Source may or not
reflect this; in order to stamp 'digital' on it, there may have been a
new coat of paint.
Uh...? As far as I know, Dave Cutler was not involved in -11D. Are you
really sure about this? Also, DuPont writing -11D? RSX started as RSX-15 for
the PDP-15, at DEC. And that was around 1972 as well. How could DuPoint have
become involved and written RSX before then? I'm curious here...
DEC was headhunting around '72 - they picked up Cutler earlier because
of what he'd done at Du Pont on his own. My dad had done an OS for the
LINC-8 for the Psych dept. at Michigan State which got back to Central
Engineering through the Life Sciences people, so that's how he ended up
working with Cutler.
Cool.
And Cutler seems to have been quite a person to deal with already back
then. :-)
He didn't write -11M single handedly, but he read and signed off each
and every line of code in it. You probably know the story about how he
had a red ink stamp that said "Size Is Everything." If he could write
code tighter than what came across his desk, the proposed code was
returned to the sender with the stamp right across it. That's not
apocryphal.
I know he didn't write it single handedly, but he did write quite a lot of
it. Just read through the sources... His name is at the top in quite a few
places...
What isn't always told is that if you couldn't ever write tighter code
(two or three iterations), Cutler used his own - but didn't necessarily
take other names off it IIRC.
Dad was pretty full of himself when he successfully argued Cutler out of
2 *bits* in a register for the error logging subsystem. It wasn't
pigheadedness on either side, but you had to formally show something
couldn't be done with n-1 bits. Even for n=2. Absolute brutality when
it came to size.
Memory hasn't been such an issue for a long time now, and now I'm off
topic - sorry guys.
We are indeed drifting way off hecnet here. I think I'll continue this
outside of the list.
I apologize for the drift as well...
