Hi folks.
Having had absolutely no luck getting the Begemot emulator
to work under FreeBSD 4.0-CURRENT, I've been modifying the
Supnik 2.3d emulator for the pdp-11.
So far, I've replaced the KL11 code with a DL11 driver that
handles four lines. Additionally, I stole the networked
tty_net driver from the begemot which now provides telnet
access to all four ports. Additionally, I'm working on a
DZ-11 driver as-we-speak, and will do the DEQNA next.
These four ports work great on the RSTS/E and 2.11 images
I have.
As well, I've tweaked the clock timing to significantly
improve timekeeping for my machine.
Also, I have been modifying an ANSI magtape util package
(ansir/ansiw/survey) to deal with the mt images that the
supnik package produces. Makes for easy exchange into
RSTS, etc.
Is anyone else out the hacking it up and interested in sharing
any work?
And if anyone has managed to get the Begemot emulator
working on recent FreeBSD-4.0-CURRENT versions, I'd be
grateful if you could share the information and changes with me.
Thanks and regards,
-skots

Really! So far I have had no luck getting Supnik 2.3 to work with the
elfje rl02 images on the PUPS archive. I've always had to use the
significantly-hacked-up 2.2 emulator instead. What did you change
and/or what disk images are you using?
I would love to find an arrangement that makes it possible to run an
emulated 2.11bsd system with large-capacity RP06 images.. that would
allow one to have around a quarter-gig of disk space. :)

Hmmm, the Begemot emulator is difficult to set up due to an
inscrutable configfile format but it runs here under BSD/OS 4.0.1
after making a couple 'tweeks'.
I wonder if the problems you're having are due to FreeBSD switching
to ELF. At one time BSD/OS used a.out also and "P11" built/ran
just fine - the the OS switched to ELF and P11 would no longer build.
I had thought simply editing the instab.s would be enough but after
doing that P11 wouldn't run right at all.
What I did was add a "-u" option to 'geni' and then regenerate the
instab.s file ("geni -u ...") _without_ the underscore characters
present. The compiler no longer generates leading '_' characters so
having them in the instab.s file causes problems. Regenerating
and assembling instab.s cleared up all the problems I was having.
Below are the changes I've made to P11 - some are specific to getting
the various IOprogs to run under BSD/OS but the changes to geni.c
are OS independent.
THe other change I had to make was to 'devices.c' to speed up the
clock - it's still not right for a PPro-200 but is better than it
was (the clock was running far too slow, now it's just ~10% too slow).
> And if anyone has managed to get the Begemot emulator

Not FreeBSD but if you're getting bit by the same thing I did earlier
under another BSD that switched from a.out to ELF the changes below
may be useful to you.

Hmm, I've been using Supnik's 2.3 emulator (on and off - I prefer
running the real 11/73 though most of the time) and now that "vi"
works (there was a bug in the "div" instruction which Bob fixed not
all that long ago for 2.3) the emulator's more useful than it was.
> significantly-hacked-up 2.2 emulator instead. What did you change

You might try using the 2.11 images from the PUPS CD instead. Create
a "tape file" (the instructions are in the 2.11 distribution directory)
and then use a "toggle in" bootstrap for the "mt" device.
The config file I use for this is:
set cpu 22B
set cpu 2048K
set rp0 rp06
set rl0 rl02
set rl1 rl02
set rl2 rl02
set rl3 rl02
set tm0 locked
at rp0 rp0
at rl0 root.rl02
at rl1 usr1.rl02
at rl2 usr2.rl02
at rl3 usr3.rl02
at rk0 junk0.rk05
at rk1 junk1.rk05
at rk2 junk2.rk05
at rk3 junk3.rk05
at rk4 junk4.rk05
at rk5 junk5.rk05
at rk6 junk6.rk05
at rk7 junk7.rk05
at tm0 mt0
at tm1 mt1
# at tm1 /zip/mt0
Place your "2.11 boot tape file" (the 'makesimtape' program which is
also available in the archive and on the CD is used to create Supnik
emulator tape files) in to the file "mt0" and then follow the
instructions in the setup/install documentation on how to boot a tape
if you don't have tape bootroms (it's less than a dozen instructions
you need to toggle in the octal for).
Oh - and since the "RP06" disk is just an image to the host computer
(to the PDP-11 it is a RP06 ;)) the image IS interchangeable between
emulators - I've used the same RP06 image under both (obviously not
at the same time) the Supnik and Begemot emulators. Works fine.
The biggest problem with the Supnik emulator is that the clock runs
far far too fast (at least with a PPro-200 running the emulator) and
after running for an extended period of time the PDP-11 system ends
up several hours in the future.

That's correct. I believe there are also problems with p11 missing
a couple of timer interrupts. All of the complaints are entirely
appropriate, the whole thing needs major cleanup. I hope one of us
will finally get around doing some serious work on it again, soon.

I've changed nothing at all really as far as 2.11 goes. Worked just
dandy even before my hacking.

The complexities of begemot, and the relative ease of use of Supnik
was the driving force behind my sticking it out with Supnik. I figured
I'd make it do what I want, since I could make it work in the first place.
Since I'm into the actual hardware emulation, as well as device drivers,
it is fulfilling my need here until I ever get a real PDP-11 again.

The same similar tweak on Supnik has me to within seconds on the hour. They're
all gonna start losing it under load anyways, but that's life when running
an emulator under non-RT ;)

Actually, I had resolved issue of linking and the prepended underscores before.
The compile has always been clean, but the program simply doesn't work.
For example, run with -b from the command line, it returns the shell prompt
almost immediately. Otherwise, when booting it simply indicates:
DCOK = 1 asserted
and goes back to the emulator prompt.
That happens regardless of disk image used, etc... I can't effect anything
other than these exhibitions.
Perhaps somewith with access to 4.0-CURRENT, and who has worked with the
code itself could find the time to figured it out? ;)

Actually my problem with the Supnik emulator is that the clock runs
_very_ fast - the "PDP11" ends up being hours ahead of the real time
after recompiling a kernel or two.
p11 on the other hand tends to run slow - tweeking the device.c value
was aimed at speeding up the clock.

With a change to 'geni.c' or by editing the instab.s file?

Yep - that's what I was seeing until I regenerated the instab.s file
by running 'geni'. The emulator would compile and link with a
manually edited instab.s file but simply would not run correctly.
Since the same RP06 image worked with the Supnik emulator I knew it
wasn't in the 2.11BSD area.

It was a change to geni.c. The Begemot I have (2.3) had apparent mods
already done for FreeBSD, but I still had to hack geni to resolv the
underscores. it was a simple change though, as I recall.

I tried the patches against the virgin begemot 2.3 code, and I'm still
seeing the unresolved's due to underscores. Just FYI that they don't
apply to the Flea-3.0-CURRENT.
Thanks HEAPs tho ;)

I have nothing against the Supnik emulator whatsoever. I use it
all the time. Before passing these changes on, however, you might
want to verify that the licenses are compatible; begemot P11 is
copylefted.

If it's not too much trouble, could you please give us more specific
details? If not, I'll try taking a shot at it; I want to compile this
under FreeBSD. Thank you.

The A-news archive "man page" article that Fischer
retrieved from Usenet of 1981, describing the original dsw,
is authentic so far as I can remember. As the article
suggests, the displayed man page is a construction,
and didn't exist as such, but it indeed described what
the ancestral program did. By a year or so later, as
documented in the First Edition manual, the behavior
and the name were already referred to as "ancient."
My, how time passes.

[this was mistakenly sent to pupswork yesterday. sorry...]
Hi there,
I've been trying to get 4.3BSD to run on my newly acquired MicroVAXII.
I followed the Ultrix route described in the docs in the pups tree.
I get as far as:
>>> boot dua0
2..1..0..
loading boot
Boot
: /vmunix

Exactly the same thing happens when I use 4.3reno instead of the Quasijarus
kit.
Any ideas?

That's correct. I believe there are also problems with p11 missing
a couple of timer interrupts. All of the complaints are entirely
appropriate, the whole thing needs major cleanup. I hope one of us
will finally get around doing some serious work on it again, soon.

It was a change to geni.c. The Begemot I have (2.3) had apparent mods
