Not too much more.. I have been restoring them for a long time.. the older
ones are a bit of a pain as they had so many revisions of the same CPU. I
was hoping to use 34s as they are they quickest to fix,rarely die, worth
little before and after being abused, and quite dependable.

Since I work hard to let people know about the archives of PDP-11 software
already out there on the net and on CD-ROM, I'd be interested in knowing
where (exactly!) you looked and how you came to the conclusion that there
was a vacuum.

Nope, it'll run on the real deal too. You have to be a bit careful:
most of the old Unices there think they're running on a Unibus
machine, so if you run them on a Q-bus machine some funny things
will happen if you go above 256K due to the lack of a Unibus map.
(This applies to the simulator, too, since it emulates a 11/53!)

I think you're confusing "it can't" with "you aren't supposed to".
The hobbyist license that Supnik worked out only allows you to run the
software under his (or another DEC) emulator. There's talk about a
very much more permissive license deal coming up, but the talk is -
so far - just talk, and it could get nixed by the lawyers simply taking
inaction on it. If and when it does turn solid, you can bet that this
mailing list will be one of the first places you hear about it.

Until I got on this list that is what it felt like. Most people don't know
about this list and only have access to the info available on the newsgroups
or peoples pages which tends to be incomplete.

I have been told that the software there *only* runs on the simulator. Will
the software on the site listed above run on real hardware or was it
modified to only run on the simulators? I was told by a list member that the
RT11 there will not run on real hardware.

I'll post a message about that whole topic tomorrow. Quite a few people I
know working with this equipment have never heard of this message list nor
found the OS images on the internet. To go one step further, old DEC (now
compaq) told me outright "We thought you were a hoax. Who in the world would
want this old junk" - they were talking about PDP1,PDP-8,and PDP-11 hardware
and software.. talking about the left hand not knowing what the right hand
is doing.... :-)

Again, I take it these images are not "distribution sets". I a hoping to
post all the distribution sets of the various PDP-8/11 OS soon (sysgen
stuff). Really need that for old hardware. For years I needed drivers or
pieces of RT11 only to find numerous sites with "RT11 programs, DECUS ,
etc.." but not the real install media. I only ever got all this stuff from
purchasing large systems from factories.. Now it's easier.. I am getting it
all from the source.

I was actually told "can't". It would not run on QBUS stuff. Probably an
error, no idea.

To be honest, I cant get to it at the moment lol...I have a ton of stuff I
just got in, the Apricot among it. As near as I can recall, it was basically
rectangular shaped with 2 disk drives on the front, the front being one of
the narrow ends of the rectangle. I am really going to tear into this stuff
tomorrow or Friday! I still havent got all of it to the house :-) I believe
I can make quite a few decent systems out of all this stuff!
And hey, to everyone who answered me, thank you so much! All this info is
coming in really handy!

Quite a few large companies still run the old stuff. Ontario Hydro for one
still runs many PDP-8s and still buys RK05 heads. In some cases it is
cheaper to run the old stuff than to get new hardware approved for use.
I had a really weird contract in '92-93 that required a cpu to monitor and
run quite a few sensors in a very hostile environment (we are talking sodium
cyanide and sulfuric acid in the same sealed room -- HCN byproducts - yuck)
for an experiment. A PC would last a day or two with such gases so I
concluded it would be cheaper to wheel in a PDP11/34 with a bunch of A/D and
DR11-Cs in it. We did so and the 11/34s lasted about a week and a half
before the chemicals ate away enough of a PCB trace to cause the CPU/RK05 to
fail. Went through 3 of them in a couple of months and the experiment
succeeded. These old minis can take a lot of abuse... and they are great for
real-time data acquisition.
For the most part now it is just collecting.....

It's not all the same font (unless someone made one up specially). The
letters "pdp" are a tweaked version of Futura (ither Medium or Book, I
can't remember which). BTW, the "11" doesn't look the same as on any of my
PDP11 docs; normally, they're Helvetica Bold, but in the logo at the top of
http://www.pdp11.org/, they're done in what appears to be a
slightly-modified Futura. The "/34" or equivalent that you see in
particular model numbers is normally also Helvetica, but stretched. I could
give you a (scalable) PostScript copy of the "pdp11/34" logo if that would
help...

Anybody know the name of the font used for the "pdp11" logo (as seen
at the top of www.pdp11.org)? I'd love to be able to do some other stuff
with the same "look", but doing it by hand in a graphics program is doing
it the hard way...

RPI had the usual variations to these gag opcode lists floating around too.
I don't know where I put my hardcopy, but the ones that stick in my mind are:
ECB Eject chad box
EDI Eject disk immediate
HCF Halt and Catch Fire (this was already posted here, but I liked the fact
that the RPI list emphasized the fact that it requires privilege)
I wish I knew where that printout was (IIRC the file was named ACM.:WORDS and
was cobbled together from various scraps, probably mostly from the outside
world), there was a lot of other nice stuff, of interest only to "power" nerds.
