I have a DEQNA in front of me. There is a micro and that is a 8751 8bitter.
The big chip is a LSI ASIC that is a linked list DMA controller. No t-11.
The RQDXn(n={1,2,3} uses a t-11. The DELQA also does not use a T-11.
Both use lots of logic in PALs and ASICs to perform several state machines
needed for eithenet. At the time of development there were few complete
and fast enough chipsets for eithernet. The DEQNA is mid 80s design and
quite old.
The DEUNA is quite different.

My local computer junk store has a VaxMate for sale. I'm not sure of the
model -- It has a DB-25 serial port, 10-base-2 ethernet, and a phone-jack
like printer port on the back, as well as an internal ST-225 hard drive
and a 5.25 inch floppy drive.
Anyway, when I turn it on it tries to boot up -- the graphical slider
thing on the screen gets about 90% of the way across and it displays the
number 83, which I assume is an eeror code since the number changes if you
boot it up with no keyboard. Anyone know what the 83 means or where I can
get a list of VaxMate error codes? Also, how intelligent is this machine
compared to a terminal? Will it actually run a Vax operating system or
does it need a server?

It's my understanding that 2.11 will run on F11 systems (pro350 and 11/23)
if properly configured but the only binaries loose are for split I&D.
So if properly configured you can get 2.11 to utilize the user/system
spaces.

Hi -

Correct. Some systems also have an 18bit only MMU which restricts
memory to 248kb max (others have a 22bit MMU and can physically
have more memory).
> It's my understanding that 2.11 will run on F11 systems (pro350 and 11/23)
> if properly configured but the only binaries loose are for split I&D.
Not likely. The kernel won't fit in 48kb that I know of. And there
will be no networking support since that requires supervisor mode
which non-split I/D systems don't have.
> So if properly configured you can get 2.11 to utilize the user/system spaces.
The skeleton of a Makefile for non-split a kernel exists but it
will take much work (it is essentially just a list of file that may
or may not be 100% current) to kick into shape. Also, remember that
programs like 'csh', 'vi' and so on are not only split I/D but
overlaid - they will not run on a non-split machine.

If we could get DEC/Compaq to allow access to Pro/Venix by UNIX source
license holders, then yes I would certainly add it to the Archive. If
there's no source code, and SCO are happy, then it could go up for anon ftp.

I'm trying to help get the kernel for the version of 2.9BSD ported to the
Pro-350. The patches supplied by Rick Macklem are slightly incomplete, e.g
there is no config shell script which knows about the new device drivers etc.
Anyway, one vital missing file is pcreg.h, which holds the structure
describing the registers of the serial ports on the Pro-350. By perusing
the file dev/pc.c, I've worked out that the struct looks something like:
struct pcdevice {
??? baud;
??? cdb;
??? csa;
??? csb;
??? csr;
??? dbuf;
??? mc0;
??? mc1;
??? mode;
??? stat;
}
where the fields are not in the correct order, and I have no idea what
C type each is. If anybody can help recreate this file, could they
email me?!
I've included below the C comments at the top of dev/pc.c.
If anybody has Rick Macklem's email address, could they pass that on too?
I will email him and see if he's got a more complete set of patches somewhere.
Many thanks in advance,
Warren

That's not _all_ your missing ;-)
Unless you have the 1985 Seismo (or Harvard - depends where you
got the tape from) update tape to 2.9 the networking code won't
compile much less run. Been there, done that. It was a fun couple
weeks coming to the realization that the networking code hadn't
been fully integrated and compiled in 2.9
I believe the 2.9-Seismo update is in the PUPS archive (should be
on the CD but my memory isn't ECC these days ;-)). It's a fairly
painful upgrade process because it changes the a.out header format
for overlaid processes (goes from 7 to 15 overlays). If you're not
real careful you'll have (as I did ;-)) a real mess: can't finish
the upgrade because the old kernel doesn't support the new overlaid
processes but you can't build a new kernel because doing so needs
those processes. Something like that. It was "interesting" ;)

Don't worry, Nicholas is trying to patch 2.9 to get it to run on a Pro.
I'm sure he will keep us informed :-)

Speaking of the Pro, I have one and have been trying to get Venix
to run on it. The rub is, there are two versions: one directly from
VenturCom (Venix/Pro) and one licensed through DEC (Pro/Venix).
Venix/Pro is freely available on the Internet at ftp.update.uu.se,
but Pro/Venix seems to be a little harder to find. Pro/Venix is
much to be preferred because you can reconfigure the kernel (in
binary) to include different drivers, etc.
I've been able to acquire all the documentation and all (almost) the
disks for Pro/Venix 2.0. A couple of the disks are apparently
unusable or missing in the set I have.
It seems to me that Pro/Venix is a potential candidate for the PUPS
archive, the snag being DEC/Compaq residual interests in it. PUPS
covers the AT&T part, VenturCom has "given away" their part, and
DEC/Compaq is all that's left.
So:
1) Could this be a PUPS addition, if a good copy be found?
2) If someone has a copy, but worries about the DEC/Compaq
aspects, can a good copy of the disks I have be acquired?
(Anyone in this category might want to respond directly
to me instead of posting to the mailing lists.) After
all a PUPS licensee is 99.999% covered, and DEC/Compaq
objections are probably to worry about the AT&T part,
which the Ancient Unix license covers...
Actually, I'm amazed I've gotten as far as I have with this, because
I've been pretty passive about finding it. It's only taken 2 years
so far.

Interesting...I know there's a Venix 1.0 and a Venix 2.0. I thought
they were both from Venturcom, with 1.0 being for the Pro-350 and 2.0
for the Pro-380. I never heard of a distinction between Venix/Pro
vs. Pro/Venix. Then again, I got into this game fairly late...I
bought my used Pro-350 around 1993 for US$100, with Venix 1.0 already
installed (also with original install media and docs).

I have the following archives of Venix-related stuff that I snagged
from the net a few years back. If you think any of them might contain
what you're looking for, let me know and I'll give more detail about
their contents.

Sounds like fun. Any hints on the correct upgrade path to avoid this
lossage?
Better yet, would you be willing and able to upload a disk image or
tar file of an upgraded system to the PUPS archive (or directly to me
if it's not of general interest), so I could use that as a starting
point?
Cheers,
entropy

As already mentioned in previous messages, I'm working on getting
2.9BSD onto a Pro 350. I'm using 2.9BSD as a starting point because
it claims to support machines without split i/d. The 350 uses the
F-11 chipset, which I have read does not support split i/d.
I would prefer to use 2.11BSD because I understand it's still actively
used, and not as buggy as 2.9. But everything I've read about 2.11BSD
says that it needs split i/d to run. Can anyone give me more detail
about this? Was support for machines without split i/d removed from
the kernel, or is it just that some of the programs are too big to fit
in a single 64k segment?

My time playing with Pro's faded out before Venix 2 was available (free)
for me to try. I've played a fair bit with Venix 1.1 on both Pro 350's
and Pro 380's. The Venix 1 series I feel is basically V6 derived while
I understood the Venix 2 series was derived from Sys III.
About a year ago Rick Macklem that did a port to the Pro series mailed
me his "Pro stuff" which included a tape and floppies. I've forgotten
what all is in that stash, but taking a peek at some old mail he mentions:

I had thought his set of patches were in the PUPS archive. In fact I
see the patches under PUPS/Distributions/ucb/2.9-pro350.

Have you been able to acquire the documentation for the DECNA card? I
think that is roughly what it is called. The Pro Ethernet card. A few
old timers like myself and Dan Lanciani talked years ago about running
things on a Pro and no-one seems to know much about this relatively
critical bit of documentation. Again referring to Rick Macklem's
correspondence (I believe I was asking him, again, about these docs):

The rumors we were able to find all pointed to this place and person
WRT documentation for the ethernet card.

Those files aren't 100% complete. Excerpt of a mail I sent last night
to Warren Toomey:

Then there's the fact that the 2.9 distribution won't even compile,
and the 2.9 upgrade patches are a nightmare...

I haven't looked for it. The DECNA is optional, and my Pro doesn't
have it. All Pro's came with an AUI port, but without the card it
doesn't do anything.

I haven't tried the 2.9 stuff at all on a Pro. I have had it
running on an 11/23+ (w/binary license) for 10 years. The
problem is the networking, as you have found.
Venix/Pro 1.1 and 2.0 run just fine on the Pro 380, and it's
pretty painless to install. I have distribution disks for
Pro/Venix 1.1, but the install disk has apparently been
overwritten with the 2.0 installation disk. And my distribution
for 2.0 is missing a couple of original disks; I have copies of
those disks, but they get read errors.
I guess the 2.9 stuff would be interesting if you got it to
work on the Pro, especially if you got networking to work.
I don't have any docs on the DECNA, but they must exist. It's
probably pretty close to the DEQNA.

Hi

Oh, it's not _completely_ irrecoverable and is "fun" in a perverse
way.
First go thru all of the executable directories (/bin, /usr/bin,...)
and identify all of the overlaid executables and save copies of them.
Shouldn't be too many but the important one is 'ex'/'vi'. A number
of programs rely on using 'ex' scripts to edit generated files (the
kernel makefiles are _good_ examples;)), and so on. Having an older
copy of 'ex'/'vi' is the main thing I remember as saving the day.

Oh, I have no 2.9 systems - this was all done 10 years ago. The
systems I run now use MSCP/TMSCP devices and 2.9 lacks support
for those.

Oh, support was NOT removed. Non-split executables (magic number
0407 and 0410) will still run.
The kernel will not fit - without split I/D it is impossible to
create a /unix image that fits within a single 64kb (actually 48kb
since the kernel stack takes 1 segment and the 'u' area takes
another) address space.
I actually went thru the exercise once (2.10 era) of creating a bare
bones kernel that would fit in - at least the linker said it would.
That was only done by ripping out lots of stuff - no networking, no
statistics gathering, almost no drivers, etc. Never 'ran' it though
since there seemed to be little point in such a stripped down system.
Even V7 was hard pressed to run on a non-split machine! In fact there
was a paper written about shoehorning V7 onto an 11/40 and the hoops
that needed to be jumped thru. Not sure but that document might be
in the /usr/doc tree of one of the PUPS Distributions hierarchy.

My new phone # is 216-761-3656 (voice mail not set up yet, will be done in a
couple of days).
I'm still not quite done with all move-related work, so it will be a few more
days before I catch up with my E-mail.
My hardware is laid out a lot better at the new place than at the old one, so
when I'm done hooking everything up, I'll have much better work conditions for
my Project. Also the new place is physically closer to the building where all
Cleveland ISPs are located, reducing the cost of leased lines and increasing
the probability of me getting one some day.
With the hardware taking up most of the space, I originally thought that my
apartment would look like Agent Mulder's, but it actually ended up being more
like Agent Scully's. Oh well, her place is pretty nice too, and so is mine now.
Just a reminder to all Quasijarus Project folks living in the USA, be sure to
watch the X-Files this evening. They'll finally tell us what really happened to
Mulder's sister, who is the cigarette-smoking man, and all the other cool
stuff.

My MicroVax (I and only) handbook vintage 1984 says the cable is a "BC22D-10".
VAX Systems and Options Catalog Oct 1984 describes the BC22D-10 as
"A fully shielded null modem cable". Two DB25F connectors, 6 wires.
The pins in use are 1,2,3,6,7,20. I would expect that "null modem"
means (from one end to the other) connect 2-3, 3-2, 7-7, 6-20, 20-6.
The implication is that the computer might need to see DTR asserted
before it talks to the terminal.

Or given that everything seems to be fine on my end null modem cable-wise,
it's possible that something more serious is wrong with my MicroVAX I.
Does your handbook list what a flashing "1" LED error code means?
I'll double-check my cabling as well.

I haven't seen anyone answering this, so here I go...
Reg. Addr.
MMR0 777572
MMR1 777574
MMR2 777576
MMR3 772516
UIPAR 777640-777656
UDPAR 777660-777676

KIPAR 772340-772356
KDPAR 772360-772376
KIPDR 772300-772316
KDPDR 772320-772336
xy in xyP?R is:
x: U - User
S - Supervisor
K - Kernel
y: I - Instruction
D - Data
PAR is Page Address Register
PDR is Page Description Register
Okay, so for the layout of the registers...
MMR0:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
! ! ! ! ! ! ! \-/ ! \---/ +-- Enable relocation
! ! ! ! ! ! ! ! ! +------ Page number
! ! ! ! ! ! ! ! +---------- Page address space I/D
! ! ! ! ! ! ! +------------- Page mode
! ! ! ! ! ! +---------------- Instruction completed
! ! ! ! ! +------------------ Maintenance mode
! ! ! ! +-------------------- Enable memory management trap
! ! ! +-------------------------- Trap-Memory management
! ! +---------------------------- Abort-Read only access violation
! +------------------------------ Abort-Page length error
+-------------------------------- Abort-Non resident
The page info is for when a trap/fault occurs, and tells in which page it
occured.The rest should be pretty obvious.
MMR1:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
\-------/ \---/ \-------/ \---/
! ! ! +---- Register number
! ! +------------ Amount changed (2 compl.)
! +-------------------- Register numbe
+---------------------------- Amount changed (2 compl.)
Low byte is written first, and this register tells how much registers have
changed part way through an instruction, which needs to be undone to start
the intruction again.
MMR2:
Virtual address of instruction where fault occured.
MMR3:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
! ! ! ! +--- Enable user D space
! ! ! +----- Enable supervisor D space
! ! +------- Enable kernel D space
! +----------- Enable 22-bit mapping
+------------- Enable unibus map
If 22-bit mapping isn't enabled, the machine will be in 18-bit addressign
when MMU is enabled. Unibus-mapping is something I'll skip for now. You
need it for DMA on a 22-bit unibus machine only.
Note that at the end of a MMU trap/abort, MMR0 bit 15-12 must be cleared
for MMR1 and MMR2 to become active again.
>From a virtual address (VA), you get to the physical address (PA) like
this:
APF=VA[15:13]
DF=VA[12:0]
PA=PAR(APF)*64+DF
The PDR looks loke this:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
\-----------/ ! ! ! \---/
! ! ! ! +----- ACF
! ! ! +--------- ED
! ! +--------------- W
! +----------------- A
+------------------------- PLF
ACF - Access Control Field
000 - Non resident; abort on all accesses
001 - Read only; abort on write attempt, memory mgmt trap on read
010 - Read only; abort on write attempt
011 - Unused; abort on all accesses - reserved for future use
100 - Read/Write; memory mgmt trap upon completion of read or write
101 - Read/Write; memory mgmt trap upon completion of write
110 - Read/Write; no system trap/abort action
111 - Unused; abort on all accesses - reserved for future use
A - Access to page has been made.
W - Page has been written to since PAR/PDR was loaded
ED - Expansion direction
PLF - Page length field
Now, have fun...

Off-topic, but maybe somewhat related to MicroPDP-11's... I've got a
MicroVAX I in a BA23 enclosure. I'm presently a bit thrown by the serial
console port. I'm used to the 9pin MicroVAX II ports. From what I've
been told, the DB25-M connector for the console requires a special serial
cable for connecting the MicroVAX I up to a terminal. A null modem cable
is not adequate.
First, I just wanted to verify that this is correct. So far I haven't
been able to access a console prompt using either a null modem cable, or a
straight through cable. So either the system isn't working correctly, or
I need to get the cable right. Secondly, if it does require a special
cable, then what are the pinouts for that cable?
I'm guessing that aside from the processor itself, the MicroVAX I is
probably a lot closer in design to its contemporary MicroPDP-11 systems.
So I'm hoping that the 25pin console port is simillar to what some of you
have worked with on your Q-bus PDP-11's.

Dear Ladies and Gentlemen,
I have got some hardware I have to get rid of by the end of February, and it's
free to any of you guys if you are willing to come and pick it up in Cleveland,
Ohio, USA.
Last November I received a load of equipment from one company here in
Cleveland. It was a complicated network of CPUs and peripherals of all makes
and models put together by Xerox and intended to be used as a dedicated
document processing system. The CPUs included one VAX, three unidentifiable
towers, and a bunch of PCs. I'm using the VAX and all disk and tape drives
myself for my own purposes, and I'm selling the PCs, but still I've got those
three unidentifiable towers and three very funky monitors that were attached to
them. There is also a very funky laser printer attached to one of them. Given
that the VAX and all disk and tape drives have been taken out of the equation,
it's unlikely that the rest of the stuff can still be used for that dedicated
document processing whatever thing, but the towers have some apparently generic
controller boards in them (VME or something like that) and other parts that can
be raided for. Who knows, maybe even the CPUs are standard (probably some 68K),
in which case someone who knows more about this than I do (NULL) may be able to
actually use these machines for something.
The only identification on this equipment are the Xerox model numbers. One of
the towers was called NS8090 File Server. It had an external SCSI hard disk and
an Exabyte tape drive, but I've reused these for my own purposes. The other two
towers were called 6085 workstations, and they were diskless from the beginning
(as far as I can tell they don't have any mass storage controllers). All three
have monitors with very funny connectors. Aside from the Xerox model numbers
which tell me absolutely nothing, there are no hints whatsoever as to what the
CPU architecture is and all that. All towers have AUI Ethernet ports.
The laser printer is called NS8000 Laser CP, and it was attached to the tower
that was called the NS8090 File Server. The connectors are 25-pin like the
serial and parallel ones, but they have slide locks like on AUI. These slide
locks and the fact that the printer was apparently never intended to be
connected to anything except an "NS8090 File Server" suggest that the printer's
interface is not parallel or serial, but something very funny.
It has been suggested to me that I take the boxes apart, ID as many boards as
possible, and try to sell/donate them to whoever finds them useful (and the
cabinets and such would probably have to be scrapped). However, the thing is,
I don't really have time for all this, and it's naive to think that any of this
stuff has any significant cash value.
Right now I'm in the process of moving to another (cheaper) apartment in
another part of Cleveland, and really don't feel like hauling that junk around
with me. I have got these three CPU towers, three monitors, and one laser
printer, all absolutely unidentifiable, that I have to get rid of. Given what a
great job I've done at identifying and describing this stuff, it would be naive
for me to expect to sell it. Therefore, I'm giving it away for free to anyone
who is willing to come and pick it up. I have to vacate this apartment by the
end of February, and if no one picks this stuff up, I will have no choice but
to throw it in the big dumpster, which would be a great pity if this stuff is
actually useful for something.
Once again, I'm in Cleveland, Ohio, USA.

I shouldn't have posted without doing the proper research. I took a
gander at PUPS/Tools/Filesys/traverse.c.gz which I'm quite sure is one
of the tools I wrote when I was finally able to figure out the contents
of that V6 tape I had (also with no docs - it was such irony to look
at the setup document on the tape *after* figuring the format out that
clearly describes the block layout 8-). I notice traverse.c.gz does
indeed use the LARG flag, not HUGE. Since few care, I'll not bother
extracting enough of Venix 1.x to see whether that is where I met the
HUGE flag or it is just my faulty memory... -- Ken
