I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Seventh Edition:

Additional notes, comments on style, and whatnot are welcome.
(It may be sensible to send anything in the last two categories
directly to me, rather than to the whole list.)
Hi,
I successfully made SIMH VAX-11/780 emulator run 32V, 3BSD and 4.0BSD.
Details are on my web site (thogh rather tarse):

(For reference ... I am writing a detailed history of Berkeley Unix ...)
Does anyone have a copy of and the story about the Univ. of Toronto
license used for their tape distributions around 1977?
In an interview in Linux Magazine, Volume 1, Number 6, in November
1999, Joy said he just took a license from the University of Toronto
and modified it a little bit and started using that for his BSD.
It was a one-page license.
I have a copy of an early one page license (from AUUGN newsletter V01.3,
Feb/Mar 1979) which was used for the Pascal and Ex release, but it says
"(first) Berkeley Software Tape" on it which seems odd to number the
real first distribution. Also the copy of the license I have is for $60,
but the first distribution tapes were $50; these amounts are both
documented in various places for 2BSD and 1BSD respectively. Since maybe
the one page license says "(first)" and "$60", maybe there is a
different earlier license?
I also tried Googling for some of the terminology but didn't find any
hits.
So does anyone have a copy of the license for the Univ. of Toronto tape
distribution from the mid 1970's?
On that note, can anyone tell me about the story of the Toronto Unix
distributions? I understand in late 1978, the Univ. of Toronto Computing
Services group and some other Toronto-area installations were providing
their own Unix distributions for standardization of their commonly used
commands and were forming the "Toronto Distribution Centre" (mentioned
by Gregory Hill, see AUUGN V01.2, Dec-78 / Jan-79). But within a few
years, the UTCS was using BSD.

Hi, all!
Sorry for slightly off-topic question, but do anybody have a copy of
original circa 1969 RS232C standard? I need it to resolve conflict with me
and my customer regarding if RS-232C REQUIRES the use of DE-25M connector
or just
RECOMMENDS it? It seems that there is a lot of interpretations of this
standard, but
no original document anywhere :(
I know it might cost $$$, but I will pay all needed fees.
All the best,
S.

I have a few Netcom boxes at home. I'll try to remember to look

That would depend on the OS more than the hardware. :-)

There were backplanes like that for the two card RL controller.

I may be wrong (but I am sure someone here will correct me) but if the
backplane is designed for the two card RL controller I think it will be 18
bit and not capable of 22 bit.

I would guess you could look at it and see how many bits are wired thru.
And, if you have a clear view of the wirewrap side you should be able to
see if it has two A-B-C-D slots in the middle. Difference in wirewrap
pattern will be obvious. :-)

What floppy controller? Dec didn't use the standard Shugart 8" inteface
for RX01/RX02 disks. If it is like the Terak which also used 801's you
are going to need to find drivers for what OS you decide to use. Good
luck with that.

You might try asking on alt.sys.pdp11 as there are a lot much more
knowlegable people than I active over there.

Ian,
Thanks for the response and the pointer to the web page. Looks like I can run 2.9 on the machine - I just have to find myself some RL's 8-)
Did some digging around on QBus, and think i found enough info, that coupled with some contiuity tests should allow me to figure out exactly how the backplane is laid out.
regards
alex

Hi all,
I am hoping this list is still alive, since I'd like to find out a bit more info about this backplane.
It's part of an 11/23 system (based on CPU) that is made by Netcom. It had standard DEC
cards in it DLV11, M8021 bootstrap board etc. Apparently the system ran a few years back
before it was put in storage. I aquired it, in the hopes of bringing it back to life and getting
it to successfully display a login: prompt.
I have read through the archives, esp. a post from Michael Sokolov back in 98, where he describes
the different types of QBus'es. Q/Q, Q/CD etc.
It looks like the backplane that I have (according to some documents written at SLAC in late 70's)
is a serpentine or sinusoidal.
A diagram on the cardcage describes as follows:
A B C D
------------>
<-----------
------------->
<------------
There is also a blurb about slot 2/CD being wired differently. Two slots on the diagram are pre-printed for RL controllers.
My CPU card is a later rev. D so it can do 22bit addressing. I'd like if possible to run 22bits, since this would allow
me at a later time to put in a 11/73 cpu that would run 2.11.
How would I go about checking if the backplane is wired for 22bits or not. I seem to remeber the standard qbuses had the W1-W4 pins (?)
that you could wirewrap to change from 18to22, but this backplane has nothing like that.
Also, in the present configuration, with an 11/23 and 128Kw, could I run v6 or v7 (assuming I can get some form of supported disk storage)? At present
I only have a floppy controller and a bunch of 8" Shugart 801 drives..
thanks in advance for any replies.
