No prob.. If I get a SLIP link up and running I'll just suck down the right
date from an NTP server on my net which is synchronized to a radio clock.
Heck, I could just hook up a clock receiver to the machine directly!
I hardly ever bother to set hardware clocks in my machines anymore. The
batteries in my VAX for the clock and stuff ran out quite a while ago, but
no problem either..

Any idea about version numbers I could check? This machine was used until
pretty recently in a production environment and maintained pretty
well on the hardware/firmware level. I don't think it was decomissioned
because of Y2K, but because they were told that they could provide a 'better'
service with a Micro$oft solution.
Last thing I heard is that the new solution is sorta falling apart all over
the place.. Not surprising to me, but they're not getting this machine back! :-)

Yep - I have seen that on the 11/93 at my place. Nice. Having the
"toyclock" to get the date/time from is real good too.

Use less power and are more reliable (also larger capacity I believe)

As I was reminded a short time ago - don't put a Qbus board into a
Unibus machine (or the other way around) :-)

SL/IP yes but 2.11 predates PPP and I am not sure there is room in
the kernel/networking for PPP (which is a much more complex protocol).
I've run SL/IP just fine - and if you have the (fairly) recent updates
to enable hardware flowcontrol you can run considerably faster than
9600 and not worry about dropped characters or truncated packets.

Ah, yes indeed! As long as the kernel's idea of the drive size
is less than what the actual disk image is then you should not have
any problems - i.e. if you put an RA60 sized image on an RA92 it
should work (at least well enough to configure the 2nd drive correctly).
Obviously the other way around would not work ;)

A TK70 controller will run a TK50 drive very nicely _and_ offer
the benefit of the buffer cache (which speeds things up greatly). I
do not know if there was a Unibus TK50 adaptor though.
An inexpensive TS05 would be a real nice thing to have about now ;)

As long as you've updated to the Y2K-compliant KDJ11-E firmware, that is.
The "old" firmware will do fine up until the end of 28-Feb-2000, when it
will promptly wrap back around to 1990. You can use 2.11BSD 'toyset'
(or the RSX-11 or RT-11 equivalent) to set the TOY clock after that date,
but at power on it'll reset back to 1990.
See the discussions in vmsnet.pdp-11 earlier this year for the ordering
code and cost (I think it's around $25.00) for the new 11/93 and 11/94
firmware.

Even if there was support, it'd be just plain cruel, even with emulated

The '94 is way cool! I'm amazed at the extensive menu-based boot ROM in
this thing. At least the RA92's are quite a bit more 'civilized' than the
RA82 on my uVAX which is more like a howling banshee..
Pity I have little UNIBUS stuff.. Most of my other DEC hardware is QBUS based,
otherwise I wouldn't have had the problem.. I have an UC07 SCSI controller
I could use for a while (but it's QBUS) to hook up a tape drive.
The machine itself seems to work fine (and seems to be pretty much 'lodaded').
Runs RSX-11 now (at least a partial setup as I wasn't able to get all drives)

OK. Got that.
Guess my first search will be for either an UNIBUS SCSI controller or
a TK50/TK70 controller as I still have some drives for those..
I have little or no 9-track reel tape stuff :-)
Thanx for the help!

OK.. Biggie here is that this machine doesn't have a tape drive, just
2 RA92 drives. It used to have a TU81, but it seems to have been junked
along the way.
No ethernet card either.. (anybody know where to get a DEUNA cheap??)
What are my options to get 2.11BSD running on this beast?
I have a uVAX 3600 running NetBSD, so I could possibly dump a raw
filesystem image onto one of the RA92's and perhaps boot the 11/94
off of it. Is this feasible? I haven't looked into it yet..
I was thinking of using one of those TU58 emulators on the PC, but I
didn't find any mention of booting an 11/94 of these tape drives
or installing UNIX from it..
I don't have any other UNIBUS cards, so I can't plug my TK70 into
the 11/94..
Any thoughts on the subject are welcome..
Bye, Arno.

In the US there are many places which sell used DEC equipment but
I do not know of any in the Netherlands. If at all possible get
a DELUA insetad - less power hungry and fewer bugs.

Yes, it should be possible. You will need to run one of the emulators
(either Bob Supnik's or Willi Begemot's "P11"). The tricky part
will be in the geometry/size of the disk image. The emulators
do not know about MSCP drives so you will have to go thru the bootstrap
process using an SMD ('xp' driver) drive and pretend you have a
RP06 or 7. Then at the last minute install the MSCP bootblock.
DD that image to an RA92 and hoo that up to the /94.
The problem you will most likely encounter is that the size will not
be exactly right for the last partition. Experimenting with the
standalone 'disklabel' program and adjusting the sizes/geometry may
be needed. If the size is changed then 'fsck -s' to force a
rebuild of the freelist will be needed.
Experimentation - I think it'd take a few tries to get it right ;)

No support for the TU58 in the kernel or boot program. At 256kb
it's barely large enough to hold the standalone programs much less
a dump of the root filesystem or anything like that.

[Snip instructions for installing a bootstrap]
No, I got the installation of the bootstrap just fine. I was told that
the bootstrap for MSCP disks uses a bug in the UDA50 that some 3rd party
controllers don't exhibit. (In my case, I have a Viking UDT SCSI controller)
I was saying I needed to know where/how to change the bootstrap (modify the
bootstrap, not use a different one) so that it will work.
I got a pointer at some 3BSD stuff on Minnie, but that code used a boot ROM on
the VAX 750 to get it's job done.
I don't have any MSCP books so I don't know where or how to change the
bootstrap to make it work on my machine.

Hmmm, ok - that wasn't clear. It read as if the documentation was
needed to install a new/different bootblock.

Yep - same in 4BSD too, I remember thinking at one time "ah, I'll
just use the 4BSD bootcode as a guide" only to find out it was
calling into the ROMs.

IF the bug is what has been suspected so far then presenting a
vector to the controller during the 4 step init process is what
needs to be done.
Looking at the standalone MSCP driver (/sys/pdpstand/ra.c) which has
the logic to specify a vector even though interrupts are not use the
logic is:
if (rainit[ctlr] == 0) {
again: raaddr->raip = 0;
if (ra_step(raaddr, RA_STEP1, 1))
goto again;
raaddr->rasa = RA_ERR | (0154/4);
if (ra_step(raaddr, RA_STEP2, 2))
goto again;
iomapadr(&racom->ra_ca.ca_ringbase, &bae, &lo16);
raaddr->rasa = lo16;
if (ra_step(raaddr, RA_STEP3, 3))
goto again;
raaddr->rasa = bae;
if (ra_step(raaddr, RA_STEP4, 4))
goto again;
raaddr->rasa = RA_GO;
if (racmd(M_OP_STCON, io) < 0) {
printf("%s STCON err\n", devname(io));
return(-1);
}
rainit[ctlr] = 1;
}
Thus it is only done on 'first open'.
It is in step 1 that the vector divided by 4 needs to be "OR"'d into
the work presented to the controller.
The ra boot block code (/sys/mdec/rauboot.s) has a loop:
/
/ RA initialize controller
/
mov $RASTEP1,r0
mov raip,r1
clr (r1)+ / go through controller init seq.
mov $icons,r2
1:
bit r0,(r1)
beq 1b
---->>>>
mov (r2)+,(r1)
asl r0
bpl 1b
mov $ra+RARSPREF,*$ra+RARSPL / set controller characteristics
mov $ra+RACMDREF,*$ra+RACMDL
mov $RASTCON,r0
jsr pc,racmd
mov unit,*$ra+RAUNIT / bring boot unit online
mov $RAONLIN,r0
jsr pc,racmd
...
I suspect that the loop at ---->>> needs to be modified to do something
special for step 1.

At least one of the changes was to give the MSCP adaptor a vector
during the 3 or 4 step init process. Normally 4.3/2.11 didn't bother
to give a vector since interrupts were disabled. It doesn't
reall matter what the vector is as long as it's non zero - the
value used was 0154 (primary/1st MSCP adaptor).
Some other 3rd party adaptors (can't recall if it was Dilog or
Emulex or ...) had the same problem.

Hmmm, I wonder if that's in the bootblock code or the actual boot
program.
The standalone MSCP driver in 2.11 has the "give a vector to the
adaptor" change so my guess is that the bootblock is where the
looping is happening. The bootbock (rauboot.s from /sys/mdec)
relocates itself to 0160000-01000 or 0157000 so a loop at 0157702
would be where the 'racmd:' routine is looping waiting for a
command to complete (or the adaptor to come ready the first time).
I thought the same "give a vector" change had been made to rauboot.s
but it would appear that's not the case ;-(

For what it's worth, this does sound suspiciously like what the 4.3
boot code did with the Viking. As far as I can remember, there is a
flag in one of the UDA50 registers that is set to 1 one the device
interrupts. The 4.3 boot code runs the UDA50 with interrupts disabled,
but polls this flag to find out when the controller has finished a
command.
On the UDA50, even if interrupts are disabled, this flag gets set. On
the viking, it doesn't. I can't remember the exact change I made, but I
got it from the sources for some later version of 4.3, which I probably
found on the internet. I'll try firing the beast up tonight, and see if
I
can figure out what I did.
My hacked around version of UW 4.3+NFS that Michael Sokolov uploaded
to PUPS should also contain this modification. Somebody could try
comparing my version to the original UW version -- they're both in the
archive, as far as I know.

And even then the disklabel changes to the HK (rk06/7) driver have
not been actually tested - the site that was going to do that had
equipment failures and that combined with the lack of interest in
or curiosity about PDP-11s resulted the the entire 11 collection being
scrapped.
So, I went and make the changes anyhow and they "should work" since
adding disklabel support to a driver is mostly a boilerplate type of
activity but there's always the chance that an error crept in.
Disklabel support for the XP (rp03/4/5/6/7) driver is known to work
well.

'fraid I haven't been _that_ route before.
What I would do today, given the presence of a Qbus SCSI adaptor in the
system, is either
1) Use a cheesy old 4mm drive (I've a Sony SDT5000 that's too small
and/or slow today for the Intel system - upgrade it to an 8mm
drive), hook that up to the PC and blast the 2.11BSD boot kit
on it (using the instructions, etc provided in the PUPS archive).
Then move the 4mm drive over to the PDP-11 and boot the tape .
2) Get a SCSI Zip drive, hook it up to the "PC" and use one of the
emulators to create a ~96mb image of a system containing the
standalone utilities + dump of root fs + tar files for usr.
Then march the Zip drive over to the PDP-11 and boot. Instead
of specifying "tape file numbers" to the standalone programs
(as in "tms(0,1)") you would use "ra(1,0)disklabel" and so on.
A Zip drive is _real nice_ to have on the 11/73 - the Zip is actually
quite a bit faster than an RD53/RD54 and the media and drives are
cheap for Zips (Internal SCSI zip drives and a 3.5" shoebox run perhaps
$150 or so).

Oh, it _should_ work - so yes, it's possible if all the underlying
pieces are in place.
Hmmm, rather than trying to use a pre-existing RP06 disk image
perhaps it would be better to get the tape images (should be
in the pups archive) and use 'makesimtape' or whatever to create
a bootable tape image for one of the emulators. Going thru a
"cold install" to create a disk image should work.
You do have floating point hardware in the 11/44, correct?

Doh! That's what comes from dashing off a mail item in a rush

It's looping around at 157702.
157702 contains 001776
-------
I am now dangerously close to getting 2.11BSD on my 11/44. ^_^
I got a SCSI disk controller (Viking UDT) and TS11 tapes, and 16 ports of
DZ11s (Anyone got jumper/DIP switch info on these?), but my problem is
lack of a boot tape.
Anyway, since I have other machines around which can grok SCSI disks, I tried
making an RP06 image on Supnik's emulator, installing the rauboot instead of
hkuboot, but it failed. The PDP-11 read the bootstrap in OK and the bootstrap
was running but it was looping (I forgot the address).
Has anyone done this before? I would use a SCSI tape to boot from but the
SCSI tape drive I have died. (Roached literally - one of the little fsckers
got inside it and got fried.)

Are you sure it was a RP06 image? hkuboot is the RK06/07 bootstrap.
How did you move the RP06 (or RK06) image to the physical SCSI drive? You
were asking about doing it with RT-11 a few weeks ago, but you *do*
know that RT-11 won't conventionally access the 65536th (and
2*65536th, and 3*65536th...) blocks on a MSCP partition, don't you? (There
is a way of accessing that last block, but you have to code it with
a .SPFUN call to the DU driver, and none of the distributed RT-11 utilities
work on that last block, even with the /DEVICE qualifier.)
Did the version of 2.11BSD you're working from have disklabel support in
the hk driver? Disklabel support there was added recently (where "recent"
= 2 years ago).

Get us the address (HALT the 11/44, either with the front panel toggle
or control-P from the console) and we'll find out why it's looping.
