Hi -
From: Bill Gunshannon <bill(a)cs.scranton.edu>
Maybe the Ultrix source would be a help in better understanding some
of the internals of the hardware.
That could well be the case. Yes, the simulator is still being
worked on and maintained.
My experience with Ultrix-11 up to this point would
lead me to believe
that it isn't bugs, but I can easily accept that it is overly picky.
I tried RSTS. As a matter of fact, I used DSKINT to create my empty
RP06 images. No sogn of a problem there.
Ah, ok. That tends to reinforce the thought that Ultrix may be
too picky about something.
I would love to us the Begemot emulator. I have the
latest version but
I have been unable to get any of my disk images to work. Can anyone
tell me if you can use the disk images from the other emulators and if
so, how?? Do they have to be converted somehow like tapes??
Yes indeed you can use the RP06 images "bits as is". As long as
the disk image is exactly an RP06 (the only size supported that I
can see by P11) nothing more need be done. In fact that's how I
switched over from 'sim_2.x' to 'p11' - I just made a copy of the
disk image and hand crafted a p11conf file.
Tapes need "conversion" because they have to contain information
about record lengths and end of file markers. Disk images are
a simple collection of bytes.

p.s. here's what I use for P11's conf file - perhaps it will be of use. The
disk image "2.11BSD" is referenced on the line 'dev 0 ./2.11BSD
1999'
