If you think either Guy, or Dave and I, expect to make much money selling the
QBUS/UNIBUS boards we are working on, you are seriously confused. None of us
are in this as a money-making exercise; there are easier ways to make a lot
more money.
And as to the hoarding, if you'd like to buy up a couple of thousand yourself,

for you all, please let me know, and I'll expidite over a name, phone number,

Guys,
there's a new release PDP11GUI 1.48.5
Some enhancements:
1. "Disk Image Read/Write":
- Now compression of 2word patterns (32 bit patterns), did reduce
download of a RSX-11 system disk from 40h to 6h.
- Fix for PDP-11/44 console firmware v 3.40: ignore "(Program)" output
after driver start.
2. Terminal windows now beeps on char, necessary for some endless XXDP
diags.
Download from https://github.com/j-hoppe/PDP11GUI/releases/tag/1.48.5

Enjoy,
Joerg

Both. Unix Version 1 was written in PDP-11 assembler, for the -11/20;
although that was a re-write of an earlier version written in PDP-7
assembler. C was developed from B in good part because the word address model
of B (inherited from its ancestor BCPL) wasn't a good match for the PDP-11's
byte addressing model. More here:

I read that the networking code in 2.x uses Supervisor mode (apparently it
needed more address space than was available with only kernel, even with
split I/D).

I've pdf'd half a dozen pages of the 360/40 development manual from IBM British Labs at
Hursley UK, early/mid 60s. I wish I had more but these only survived because dad used
to bring home binders with these single-sided pages for us kids to draw on, and my
parents kept them. They may not even be from the same document, but it's just for
interest's sake.

You never know until you try.
Anyway, the Alphaserver 4100 has four midsize muffin fans and I found them
trivial to take apart and trivial to replace the bearings which were a
standard off the shelf part. It was easier to fix the fan than it was to
replace them since DEC had a custom fan with a speed sensor built in that
proved impossible for me to find.
It changes from model to model and generation to generation.

Hey Jon!
Thank you for the tips, i will see if i can open it up in someway, the
fan is kinda like a laptop blower style, but a bigger version of it :) I
think i will need to buy new bearings for it when i have read on google
about the fan.

Don't be nasty Al!
I was willing to scan the addendum and covers if needed.
I also did not know if others with interest needed...I am glad the book
is scanned already as I do not care to blow mine apart... glue backing
gets pretty brittle on these things. The addendum is a loose pamphlet that
was just with the manual

We have in the library:
"raytheon 706 computer users manual"
at SMECC.
Wanted to see if it was online somewhere.
Nice shape tight binding with an additional errata and addendum
pamphlet accompanying it.
I see bitsavers has manual but not pmphlet.Also there is no color front
and back cover, which
if you have the computer is cool artwork for a display. -
Anyone with a 706 out there?

Dumb question...did the '451 have a mechanism to work around the
instruction restart issue in the 68000? Or was there some other way
that was handled?

I'd be grateful.
