-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...

Greg,
Bring up SimH (VAX) on a platform of your choice, then register and
acquire VMS licenses. This is the easiest way to start. More support
is available for VMS than anything else. After you get the VAX (and
VMS) up and running, connect to HECnet. From that point on it won't
really matter which direction you choose - you will be on HECnet and can
add systems as necessary.

Sure.
Some time ago, John Wilson, confirmed for me that his E11 systems can
be configured to accept modules that would look to the PDP-11 OS
running as if it were talking to something specialized, and not
originally part of the regular PDP-11 series of modules. (Of course
that's my phrasing and how I heard or read about.) That's how I would
start, but I'm not sure if his program could be told to work as if it
were a J11 setup or any of the others.
Hmm.
I believe it might be possible to convince (or confuse) E11 that it is
actually one of those, and running something along the lines of the
appropriate R* OS from DEC,
That might be possible. That might also be possible with simh, given
that the source code is available and it compiles on most anything.

I just picked up four more LA120s with some 11/84s and a bunch of
RA90s. (very happy!) I will check tonight if you don't look at yours
by then.
For example, the RFxx drives (all of 'em, I think) used a T11 and I'm
pretty sure ran some variant of RSX-11S.
Wow, I didn't know that, that's neat!
The HSC controllers had PDP-11s in them, didn't they? I don't remember
which model but I bet the OS was another RSX derivative.
The HSC50 uses an F11, the HSC70 and HSC9x use J11s.
Some of the bigger DECserver terminal servers were PDP-11 based (not T11,
but an 11/53 for example). Don't know if the little ones (e.g.
DECserver-100, 200, etc) were T11 or 68K based.
The -200 is 68K-based. I don't know about the -100. The -550 is the
one that's basically a PDP-11/53 with different EPROMs.

I have no problems calling -11M a redo of -11D. As far as I know, it was not done by Cutler at DuPont, but something he did after starting at DEC. But that is just what I gathered from reading various sources over the years... I could very well be wrong.
One of the goals of 11M was to get something that could run on a really
small PDP-11 without an MMU, which 11M can. (I seriously doubt that
could ever be done with -11D.)
-11M+, which came later, was basically reimplementing some of the stuff
in -11D, since -11M+ had as the target the large PDP-11 systems.
Specifically the 11/70, as well as the never introduced 11/74. Which is
why -11M+ also have a very capable online reconfiguration tool (that
turned out to be useful in general, but it was specifically written for
the 11/74).
So -11M+ requires even more hardware than -11D, but does things
differently than -11D.
One of my favourite Cutler stories was that Sales was trying to
differentiate the products by telling customers that -11M (the cheaper
OS) wouldn't support as much memory as -11D. No doubt this was a
bastardized version of saying that -11M didn't *require* an MMU. In any
case, D cost more than M, by a lot, but it wasn't readily apparent why.
Cutler was not pleased with this scenario for various reasons. He was
offended that someone would spend more money to waste resources when
they could have a tighter system cheaper, IIRC, but he was also mostly
just pissed because it was not true that M wouldn't handle as much
memory as D if you had it. So he sent his *own* letter to customers,
telling them that the price difference was not justified in terms of
expansion. Sales loved that<!>, but -11M has done fairly well since.
Indeed. -11M has done very well over the years. Especially if you include -11S and -11M-PLUS in that. All other versions of RSX faded into obscurity, more or less.
And Cutler seems to have been quite a person to deal with already back then. :-)

I remember MicroPower Pascal, but never used it, or even saw it.
-11S is always diskless and memory resident, so it's easy.
-11S, -11M and -11M-PLUS all share the same sources, by the way. (At least as far as capabilities are shared - there are sources that are M+ only for instance.)

It's good that you brought this up, because I was going to ask about
examples of devices that used embedded PDP-11s, probably mostly DEC made but
not always.
For example, the RFxx drives (all of 'em, I think) used a T11 and I'm

Not the RF11 :-)

Subject: RE: [HECnet] This is probably been asked already but....
The PRO was for later VAXen. 8800-range, I think.
That must be where I saw it, because I remember a VAX with
what was clearly a PRO attached to it. We used to joke that
it was the only way DEC could sell the PROs :-)
The 86x0 uses a T11, and runs RT-11.
Was it like a FALCON/KXT11 board based thing, or some
custom T11 board?
How (where) did they get RT11 for it? The T11 had a few
oddities (e.g. no bus timeout traps) and AFAIK RT11 was never
supported on T11 systems. I've heard that there was an
unofficial, hacked up, copy of some RT11 release that would
work but I never saw a copy.
The 86x0 does in fact run a real version of RT-11. The disk sub-system
was a RL0x (can't remember if it was 1 or 2). It had its own set of
quirks - to say the least! The sources have macros to deal with the
T-11 differences. They were in the middle of the changes to RT-11 just
as I joined the group. One of the guys spent quite a bit of time in
Marlboro, MA trying to get the sub-system to deal with the RL0x.. It
was a beast! :-)
It's an RL02.
Not sure what part of the RLV12 or RL02 that was a beast. It's a bog standard RLV12 and RL02. RT-11 in general supports this without any issues.
Yes, there is a Q-bus in a VAX-86x0. It's in the same box as the first Unibus. The Q-bus only have the RLV12, and no other/additional peripherials are supported on the Q-bus.
The FE runs RT-11, but normally a specific program is started at boot time, which manages the whole system. You can reboot the FE with a special switch to tell it to not run that program, and then you instead get to the normal RT-11 prompt, and can do the same things as on any RT-11 system. You can also run the FE application by hand at that point.
The FE is a VAX-86x0 specific board, so I'm not sure what peculiarities might be in the hardware, which this version of RT-11 is adapted to.
The Q-bus comes out of the 86x0 backplane on two flat cables, which goes into the expansion box.

Has anyone been able to get to PROCESS.COM lately? I am trying to get
their to renew my Multinet license but it keeps timing out. Until I get
this sorted out SG1:: will not be able to support tunnel links.
Thanks!

Well WHOIS also points at the US, mainly PA.
Israel eh? Sounds like someone got hijacked :)

What did surprise me was that when I did a traceroute to www.process.com, it took me to Israel. I wonder whether that's correct or not.
The FTP server traceroutes more logically seemingly to Massachusetts somewhere.
