This might not be state-of-the-art (but thats not the point anyway), I'm
running p11 version 2.5 on an FreeBSD 3.4 machine and it works ok, the main
problem I have found is that after a while the clock starts to run slow,
at the momement it thinks it's christmas eve (after beeing up about 130 days).

Where can I find this Begemot P11 Emulator?? I visited the Begemot site
but the link to products doesn't appear to work. I have tried E11 (demo
version) and the Supnil Emulator, but have never heard of this one til now.

Hi,
Harti Brandt, the guy who wrote this package is shortly (I hope :-))
going to release a new version that includes a clock patch that Steve
Schultz dreamt up.
Regards
Robin
Currently running P11 on linux

There is an oldish version on the pups archive. I believe that harti is
going to release a newer version soon.

The bug is an arithmetic overflow in the clock computations. After
about 24 days (with 60Hz power in the US) the number of ticks the
virtual machine has been up overflows 32 bits and time behaves very
strange.
Apply the patch below to 'device.c' and the problem goes away - it did
for me.

I *have* *run* the standard Unix V6 distribution on my PDP 11/34. Works
just fine.
I also compared my V6 distribution image with the one on PUPS (years ago)
and they matched just fine.
Load the pack from the RK05 image after the 100 (IIRC) block tape to disk
loader program [how you get it there is another issue, of course... 8-)],
boot up, type rkunix at the "@" and away you go.
I did not use the tape to disk program on the tape image, however -- I
didn't have a tape drive at the time IIRC. I have a standalone program
that used a parallel port on my PC and a DR11 on my PDP-11 to write it,
IIRC, but I might have used XMODEM and a serial port -- its been a lonnnng
time since I did it.

Yes, but it doesn't boot on an 11/34 :(
That's the problem.

Gosh, it was quite a while ago that I tried P11 on a FreeBSD system.
It was pre-4.0 as I remember - perhaps 3.5 or 3.6

Quite welcome! Getting rid of the M4 macros and distilling the
config file down to the basics makes it much easier to see what
is going on. Coming up with that first config file was a day
or so of fun ;)

You're welcome - it's been a lot of fun over the years. The past
couple years development has slowed down, combination of too many
other projects and not a lot of room left to stuff new features in ;)
