Hello,
I know some of you are former VAX field service technicians or
have other deep working knowledge of this: what exactly (!)
does it take to upgrade a VAX 11/780 to a VAX 11/785 (or
11/780-5 as it was called.) I believe this includes changing
the SBI backplane. But what else does it include? Is the
console computer any different? Power supply?
As you probably all know, I have the 11/785 board set on
hand but no cabinet. Now I have the chance of transporting
one or two 11/780 accross the country. Those are in real
good shape as I gather (were stored inside!) So I figure I
rather have a nice 11/780 than a rusty incomplete 11/785
that lacks a console computer. And with some chance I can
upgrade one to an 11/780-5. So, what does it take?
thanks for your advice,
-Gunther

The CPU backplane gets swapped along with the board set.
I believe the console 11/03 may get more memory as well (my memory
is a bit hazy on that). IIRC it goes to 28kw from 16kw.
I think power is still the same.
The console software load is different
The 11/785 has more wcs so you need 11/785 console software with
different microcode -- so without the RX01 disks you'll never
boot the machine.

Thanks Bill and Tim, this gives me some idea.
I might actually be able to get a SBI backplane assembly
from an 11/785 otherwise in not so good shape (Will?)
But
I'm not sure I can get the LSI-11 console computer of a
11/785. So it sounds like I need just one additional
RAM board for the LSI-11? Does that have a product code
or number that I could ask or whatch out for? Would it
come from a second LSI-11 (e.g., being just another
memory board of the same kind?)
The software and microcode may end up being more headache.
First I hope I will get any RX01 disk drive to begin with.
Then where to get the software from? Could it be copied
from an existing 11/785 that someone else might have?
thanks,

Gunther,
I *may* have the boot disks for one of my 785s. I'll check in the next week
(I'm at Linux World this week). If you haven't heard from me by the end of

Only on topic if it's considered a use for NTSC monitors...
Anybody know where to get a TV tuner for a good price?
Sony had one for RV's but that was IIRC $300+.
I figure I'm going to take the circuit board out of a $80 VCR
and toss the rest. Seems kinda wasteful though.

Pick up the next VCR you see on the side of the road on
garbage day. The mechanism may be broken, but the tuner
probably still works. For a while there, everyone was
throwing out their Primestar dish and decoder, and
those had an easily separable TV tuner and RF modulator.

We have seen small 5" TVs on sale for around $20 that can be powered
either by wall wart or 12VDC from a cigarette lighter. Occassionally I
see VCRs for sale at thrift stores for about $1.00. I have at least five
VCRs here that are headed for the recycler ... how many did you want :).

I have a "few" tuners available.
ATi only works with ATi video boards that have a fun S video input plug
that supplies power etc., but they are great fully modern tuners.
Proton Tuner, best consumer unit you could buy, but its an early model that
only tunes 40 cable channels.
Sony TU 110 (I think) designed to work with a PV something monitor, but a
clever chap could wire up power etc. easy enough.
$30/$20/$7 plus shipping.

+AD4- I don't like pulling apart possibly working machines
Me neither. But for broken ones that are nonunique
esp VCR's, +ACE-IBM PC's, I'm pretty tough. I give them
some time (1/2 hour) max to 'do something neat' under
my care (in dissasembly) If it flunks, I part it out.
P.S. Tom Owad, the PC portable works fine, just a
few internal cables in the wrong places.
Almost flunked the 1/2 hour rule. Then I noticed
the video subsystem ran off of a single 12V source.

When DMA Systems went under, Ricoh was the company that bought them. The
removeable drives that DMA made (I made some of the prototype boards for
the original design) used a standard PC power connector. If the board
you have is different, you might check with Ricoh.

If that is the only part that you want, John, why not pick one up
at a thrift shop. It is certain to be a damned site less than $80!

Actually there is an answer to that, only not a great one.
The later the model, the smaller the circuitry.
1970: 12+- boards 1980: 2~3 boards, 1990: 1~2,
Then the boards start shrinking inside the case.
What I really want is just the tuner, or a real small thing.

Second hands electronics shops tend to have dedicated TV tuners as well.
Otherwise, you could try looking for an old video system, the kind which had
the tuner in another box instead of integrated into the VTR itself.

Thrift stores are about the only place I see the modular tuners that once were
popular with "component" video recorder systems. SONY made them as did a
number
of other makers, but the SONY ones are common because they were made to go with
BETA format equipment, though they're still NTSC tuners. I'd bet that if you
find one, you can get it for about $5 here in the USA.

It might help to know a little more about what you are trying to
accomplish with it, to know what other parameters there are, such as what
range of channels does it need to tune? What kind of output do you want?
What physical, price, power, constraints are there?
For example, if your goal is merely to make a TV out of a monitor, then a
VCR would add extra funtionality.
Some cable boxes have composite output.
Some closed caption boxes (VR100) have RF and composite in, and
RF and composite out.

TV Tuner
= Demodulator
= RF to NTSC. RF in on an "F" jack. In this case
I would prefer VHF/UHF on an antenna but Cable would
be important sometimes, yes. NTSC composite out on
a BNC or RCA jack. Audio on RCA. Digital tuning.
DC power preferred, not essential.
My video monitor is a modern OT scap flatscreen but it
would be neat to be able to use VGA monitors too (A VGA
converter is yet another topic) Also I have an Atari/Comodore
monitor or two.
I would pay $50 for a 10"x10"x2" type deal if it was perfect to
the task. A mini one, like 4"x4"x1", readymade, on =<1watt DC
power, maybe $150.

Copying it will be a snap for anyone with a PDP with either RX01's or
RX02's if someone has a spare copy to begin with.
Even the VAX can copy it with it's single RX01.

Hi Gunther,
I know I have said this before, but I have and will scan in the 11/785
Installation manual that covers the CPU upgrade. I will try to do
some tonight.
According to the upgrade manual:
Upgrading the KA780 to a KA785 consists of replacing the CPU
cardcage and backplane assembly, inserting new CPU modules,
replacing the memory board in the LSI-11, and attaching a new
logo to the CPU cabinet.
So you need the 11/785 card cage/backplane and a new memory
board for the console computer. No changes to power supplies.
I would think that it would be hard to source the new card cage/
backplane and LSI-11 memory board, but if you can get your hands
on a working 11/780 take it! They are really nice old hardware, its
only 0.5 of a VUP (although when you compare 1VUP to 1.5VUPs
its 33% increase).
Regards,
Tim.
