It seems to my memory that we used just a RCA phono jack to the board,
and RG58 with RCA phono plug on one end and a BNC on the other with
a standard black and white security video monitor in the field, typically already
located at the site as part of the existing video surveillance, so service
personnel didn?t have to carry anything with them.
We used a RF modulator, channel 3 or 4, on a larger screen TV set
in engineering spaces for ease of viewing when developing or modifying the
embedded application we were running on these, again it seems to me we picked that
up at Radio Shack when we needed one back then, and fed it directly from
the OSI board. It seems to me we got power for the modulator from the
same connector that the video appeared on. We ran these on a battery
backed up linear power supply, in the event that AC was lost to the facility.
We didn?t need video with our application, so video was never left running
in the field.
I can?t remember when I last had that Superboard fired up, but I did it with
a 5? black and white security monitor from my truck I use to setup video
camera views with. Nothing extra involved, and it hasn?t been powered
since. It is stored downstairs with the PET and a Data General Micro Nova.

I'm making some progress on restoring my HP-2116A system.
I really need the manuals at this point. I see a couple that are related
to the 2116 on bitsavers:
http://bitsavers.org/pdf/hp/21xx/02152-90004_2116FPP_sep70.pdfhttp://bitsavers.org/pdf/hp/21xx/5950-8704_2116B_classVol2.pdf
However I really need something more like a service manual. Schematics,
test proceedures, etc.
I know there are quite a few folks out there with 2116A systems. Anyone
have electronic versions of the docs?
I'd be willing to do the pdf conversion if someone would loan me paper
manuals.
FYI: I'll be out of town tomorrow through sunday. (SLC, UT)
I continue to put up more pictures:

I sealed the edges of the faceplate/CRT with
aquarium-grade clear RTV. This was outside the field
of view permitted by the housing of my HP terminal.
Keep everything absolutely clean (I used acetone) so
that no dirt or smudges will be permanently trapped
between the two surfaces. Use good lighting, outdoors
(because of the acetone).
I would STRONGLY advise ALWAYS replacing this
faceplate. I'm sure that having it in front of the CRT
itself will be very helpful if there is an implosion.
I have read that the neck a a CRT tends to be shot
through the front of a CRT in the event of implosion.
This would be bad.
Once assembled this way, there has been no optical
affect whatsoever visible on my CRT. It is impossible
to tell that there is a space between the CRT and
faceplate (in my case, around 1/4-1/8".

Glues aren't going to be effective at all, and you can't silver solder
aluminium.
It's possible to TIG weld aluminium and that might not be expensive if
you know someone who has a TIG welder (they're often found in small
engineering shops and car body shops). It's also possible to MIG weld
aluminium, but TIG is more common and tends to give better results in
my experience.
If you want to try it yourself, there are various forms of aluminium
solder, but most need special fluxes to cope with the oxide, they can
be tricky to use (depends on the grade of aluminium, which is rarely
pure, it's normally really an alloy), and not very strong. They also
need a lot of heat because aluminium conducts heat away extremely well
(this is also one of the problems with MIG welding it). Aluminium is
often soft-soldered with a stainless steel scratch brush to remove the
aluminium oxide under the solder pool, or done with an ultrasonic
soldering iron (expensive -- I once nearly bought a *cheap* one for
UKP300).
For hard-soldering, or fusion welding really, the best stuff is
Techno-Weld. It really works, and you can get it in the States as well
as in the UK:
http://www.techno-weld.comhttp://www.techno-weld.co.uk
One of the basic "kits" of rods would have all you need; they also
include the scratch brush, abrading wire and instructions.
Or just rivet or bolt an L-shaped bracket on each side.
Whatever you do, be prepared to file a bit off the broken edges to make
sure it fits back together; whatever broke it probably stretched and
bent it too.

---------------Reply:
The /40 was considerably different; bank-switched memory, intelligent
display & printer, different keyboard etc. (Also more than twice the
price of a /20).
Both the display & the printer had their own microprocessor (6504)
and could be mounted off-board.
See Interactive Issue # 5 for a preview (on Rich's site). Also see
issue # 8 for a description of the "official" Rockwell case. There were
also larger cases to house the /20 or /40 along with its expansion
card cage.
There was an application note (R6500 N12) describing how to
build a video interface (including the software listing) and it even
references Lancaster's TVT Cookbook! Those were the heady days
of OEM support...
If you have trouble finding a display maybe that's the answer;
just stick it inside an old monitor or terminal. BASIC & the editor
are 80 (79) column capable BTW.
I did indeed find some extra display covers; I'll be in touch with you
(Ethan) & Jules off-list.

I was contacted this week by Larry Metzler of Green Bay, Wisconsin. He is
looking for a home for an IBM 513 reproducer and a 405 accounting machine.
It is too far away for me. Anybody interested should contact Larry at

Nothing was wrong with them. Somehow I managed to miss them!!!
I went back today based on your statement that there would be someone
with them cheap... I found the guy, and realized that I never saw him
Saturday. I don't know how, and I'm kind of annoyed that I didn't see him.
I got a good deal on a pair of them. 2u, dual p2 400 MHz with dual 9.1 GB
scsi drives, $40 each. His Saturday price was $55 each for the same
setup, and I would have happily paid the extra $15 each to avoid the
drive a 2nd time (in fact, these units cost me MORE then the saved $30
combined between tolls, gas, and my time).
So I'm happy now as I can replace my tower server and get it into my
rack, and replace 3 other machines acting as web and FTP for a series of
domains with a single one of these rack servers.
Thanks for the heads up that he was there.

I went to the Trenton Computer Fest today. I didn't get over to the MARCH
table, sorry. I did see John Allain however, but down the end of a row,
and by the time I got down there to say hi, I lost track of him.
Back to the point. I picked up a pair of NeXT slabs for $2 each. I think
even Sellam would agree that is a good price ;-)
One is a Turbo the other is a Color. No idea yet was is in them other
than visually, there is a floppy drive and a hard drive. I've never
played with a NeXT, and at that price, I wasn't going to ask many
questions.
The Turbo has a DA-15 connector that looks like a Mac RGB connector. Is
it compatible with Mac monitors? The Color has a connector that I don't
know what it is called, but looks like a Sun monitor connector. Is it
compatible with those monitors? I'm crossing my fingers for a yes on both
counts since I have both available to me already.
And to verify, the keyboard/mouse uses ADB correct? These slabs were just
the computer, nothing else. (although I did find a guy that had a NeXT
mouse, but he was holding it to sell with his MacTV and wouldn't part
with it. I considered getting the MacTV, but since I got one from John a
while back, I decided against spending the $50 since it didn't have any
docs, software, cables, keyboard, remote, or the correct mouse).
The only other thing I picked up that might be of interest to this group
is some kind of video conferencing terminal. I don't know anything about
it at all yet, I wasn't actually interested in it, but the guy said if I
took it away right then, I could have it for free, so I took it simply
because it looked cool.
Over all, I was a little disappointed this year in the items available.
It is only the 2nd time I've gone, the first was two years ago, and I
remembered there being far more vendors with a better selection. This
year was a bunch of so-so priced used PCs, TONS of old laptops, and some
over priced used Macs. I was surprised I couldn't find a decent deal on a
rack mount PC server, or much in the way of RJ-45 patch panels (I needed
two 72 port ones, I was able to find two 48 port ones at an ok price, and
that was about it). Its possible that some of the vendors just weren't
there yet or fully unpacked, I was there from about 10 am to 12:30. I
also didn't go indoors anywhere, so I may have missed a bunch of other
dealers (I had limited time today as I had to be back home by 2, and it
takes about 1.5 hours on the drive).
Anyone else get anything of interest? Oh, and Hi John, since I didn't get
to say it to you today. :-)
