I also remember running PDP/11 Xenix. The article is basically correct,
although Microsoft (or HCR) did add a working paging system that enabled
simulation of split I&D on small PDP/11s like the 11/23, 11/34, and 11/40.
I also remember that my copy of the installation document had been printed
by Microsoft's PDP/10 (referred to as the "Microsoft Heating Plant" :-) in
the printout). I wish I still had the tape and that printout. Sigh ...

Hello,
I'm writing a new networking protocol into the Linux kernel. I have to find the place in which the multiplexing of the incoming packets are done and sent to the initial handling functions of the appropriate protocols, according to the protocol types (x25,ax25,ip,appletalk,etc...). I think net_rx_action function does this. (version 2.4.8). W
Why does it searches two lists, why 2 lists (ptype_all-ptype_base)?
Second, what is the mission of dev_add_pack dev_remove pack functions in net/core/dev.h. I've heard they deal with protocols. But I am not sure.
Anyone interested in or know any person who knows about???
Arda...

In 1979 all that existed of Xenix was a silver brochure from Microsoft
but there was no distribution. I wanted it to run it/sell it, seeing that
you could do the timesharing thing just like back at college, except
without a giant machine behind glass. I contacted the then tiny
Microsoft, asked, begged, pleaded but they had nothing to sell.
After multiple inquiries, they finally told me that they didn't have
Xenix yet, but they expected it to arrive shortly. Arrive? From where?
I was told, from Human Computing Resources (HCR) in Toronto.
Ahh, interesting. So I called HCR somehow got them to commit
to an early delivery. After a few weeks, and several dollars, the
day came. MS wanted a PDP-11 and 68000 version and was
only after the PDP-11 distro, I was 1 week ahead in the queue
from Microsoft. So, as I was told from HCR, I had the first Xenix
distribution in the US, ahead of Microsoft. I ran it on a LSI-11/23
with insanely expensive 256Kb of memory and a giant 20Mb
drive from Charles River Data Systems. It also had 2 eight inch
floppies (errrtt, clunk, clunk, errrrttt), and 2 four port serial cards
that each ran a VT100. The distro came on a 9-track tape (which
I still have) and the take drive was this weird, front loading thing
where you loaded the tape in the front like a big floppy and it
auto threaded the tape (sometimes). As I remember, it seemed
pretty fast, I'd start up stuff on all of the terminals, just to do it.
Of course, it wasn't that fast but at the time....
The Unix itself was a more or less pure Unix v7. The only thing,
as I remember that made is Xenix, was the boot message and
the captions on the man pages. There was no vi at that time,
the editor of choice was "ed". It did have a nice /usr/games
and I got a Zork for it from a friend.
We ended up selling a few of the boxes. The company was
called MSD. The only record of such is in a 1981 (Jan?) issue
of Byte with our little ad in the back. And that's the story of the
first commercial Unix sold in the US.
I am trying to get a KFQSA to work with 2.11BSD on a pdp-11. It always
fails with an error in the SA register during the transition between
STEP 3 and STEP 4 of the initialization sequence.
The SA register ends up with the value 101513. The error bit is set and
I think that the rest is an error code. I can't find a reference to
describe these error codes.
An RQDX3 and a CQD-223 in the same machine initialize fine. The KFQSA
initializes in an MVIII using NetBSD 1.5.
I have looked over the initialization code from NetBSD, Ultrix-32,
4.4BSD, Ultrix-11, and 2.11BSD. The values being sent, are all very
similar. One difference is that the VAXen OS use polling during the
init, and the pdp-11 code uses interrupts.
Any suggestions or comments about the MSCP 4 step init and how it works
on the KFQSA?
A pointer to error code reference would be great too.

Hi there,
The pdp 11/44 is working with a minimal configuration!
Thanks to Bill Gunshannon and Milo Velmimirovic.
The M7090 CIM is now doing RS 232 and gives me output (i get the console
prompt >>>) the backplane only contains memory and the cpu-cards.
The connector M9202 connects the two planes. I tried to boot the RL11 with
one of my RL02's but i didn't work, i guess this is because i don't have a
UNIBUS terminator. is it possible to make one myself ? i could make a
dual-sided PCB. or is it possible that the backplane itself is terminated
(like small qbus-systems have)?

yes there are two 40 pin connectors. so it's a interface, i guess i don't
use this...
i guess i might use the Ethernet cards, the SMD-diskcontroller and the
RL11. does anyone have the pinout of the M7792/M7793 Ethernet-controller ?
i also still have no idea what those cards might be:
> Ramtek 508295/508297 (has a 50 pin connector)
> Eikonix 821-015cs (handwritten: 785-283)(has two 50 pin connectors)
if anyone has a spare unibus-controller for ciphertapes (pertec-interface),
please contact me.

hi,
i never used rsync, so sorry for my question, but i have some
problems ...
1) i can't find any CD image in the "Mirroring" directory
2) launching
rsync -avuz --exclude 'CD_IMAGE.*' minnie.tuhs.org::UA_Mirroring Mirroring
as explained in http://www.tuhs.org/mirroring.html give me no result ...
no files nor dir. are written and the rsync exit without any kind of
error ...
what's wrong ?
we at freaknet medialab really want to mirror the site and distribute
the 2 CD package :)
tnx all,

My first unibus-pdp...
I picked up the box this weekend, without any additional equipment or
information.
They also told me is is configured for a 20 mA current loop, but i don't
have a working current loop term. is there a easy way of converting 20mA
current loop to RS-232 ?
I found a posting in classiccmp that says M7090 might be configured for
RS232 or current loop(i don't know if they meant the MUX or the CIM M7090
or both), is there a way to find out without blowing things up ? i do have
a VT420, maybe i can do current loop <-> rs422 ?
i didn't power up the box yet, first i'd like to connect the correct
console and check the configuration. maybe reduce the configuration to
RL11, DEUNA and disk-controller? another problem is the media, i'd like to
install 2.9BSD, but how ? i still hope that one of those unidentified cards
turns out to be a ciphertape-controller (Pertec-interface for my second
cipher F880).
any help, information or link is very welcome.
-- regards, lothar
This is the actual configuration:
<-power supply / frontpanel->
M 7090 - - - - dual height KD11-Z 11/44 console interface module
- - - - - - empty (this is where the optional CIS belongs)
------M 7093------ hex height FP11-F 11/44 floating point module
------M 7094------ hex height KD11-Z 11/44 data path module
------M 7095------ hex height KD11-Z 11/44 control module
------M 7096------ hex height KD11-Z 11/44 multifunction module
------M 7097------ hex height KK11-B 11/44 4-Kword cache module
------M 7098------ hex height KD11-Z 11/44 UNIBUS interface
------M 8743------ hex height MS11-PB 1-Mbyte ECC RAM (-BH)
- - - - - - empty
------M 7486------ hex height UDA52 Controller for SDI disk drives (UDA
SI)
------M 7485------ hex height UDA50-A UNIBUS to radial disk interface
------M 7762------ hex height RL11 RL01/02 disk controller
M 9202 ---M 8729-- dual height M9202 / quad height M8729 no info.
M 9202 - - - - empty (badge says hex SPC slot)
- - - - - - empty
- - - - - - empty
- - - F - - empty, F is a bus grant continuity (single height)
------SC4110------ hex height
------M 7814------ hex height DZ11-C 8-line 20mA data MUX, 50 to
100-Kbaud
------M 7792------ hex height see below
------M 7793------ hex height see below
- - --Ramtek--- quad height no info
- - - - - -
addition to descriptions:
M7485-YA UDA50-A UNIBUS to radial disk interface PR board with blasted
ROMs
M7792 DEUNA port module, UNIBUS to ethernet microprocessor. (1 of 2)
M7793 DEUNA link module, M7792 to ethernet bus line unit. (2 of 2)
i don't have any reliable description for the M8729, i found a with google:
"DRU-11 CA" parallel DMA.
the SC4110 (Emulex) is probably a SMD disk controller, at least the heavy
disk was attached to it.
there are two cards for which i found nothing:
Ramtek 508295/508297 (has a 50 pin connector)
Eikonix 821-015cs (handwritten: 785-283)(has two 50 pin connectors)
while cleaning the box i found three bus grant continuity cards (single
height). it is possible they fell out during transport.
i've read akos varga's unibus basics, but i still can't tell if this is a
valid configuration. i found a badge on top of the box, which says the
M8729 is in a SPC slot and the "second" part of the M9202 is in a hex. SPC
slot.

I'd really like to get my hands on MERT, but past correspondence from DMR
suggests that it was probably never released outside the labs. So, are there
any tapes lying about?
