When I reformed the 1967? capacitors in MARCH's straight 8 I took some
data showing the improvement in leakage and also measured capacitance and
ESR. I couldn't find original spec for the capacitor but the values
seemed reasonable compared to datasheet for more recent capacitors.

My first job was software maintenance (on site) for DEC’s PDP11 typesetting 
software.  The sort of machine you described was the common low end typesetter 
for our customers.  High end came from companies like Autologic and, later, 
Mergenthaler-Linotype, using what amounted to an ultra-high resolution CRT on 
which the characters were drawn by an embedded computer.  I remember CG and 
Mergenthaler-Linotype for these disk machines, don’t think we ran into AM.

I wonder about that.  It seems more likely the disks are in English, but use a 
non-standard character set.  Typesetting systems in that era tended to use 
6-bit codes which were specific to that industry and came in variations 
depending on the specific market.  Those originated with punch tape driven “hot 
metal” typesetting machines, I think “Linotape” was a trade mark for those.

Here's a photo of the rack, with the Boeing part numbers visible:

Some Googling of those numbers didn't really reveal much. People love to
talk about the guidance computer in the missile itself, but I can't find
much about what they used when turning the keys.

I like the little placard on the computer about encrypted data in memory.
The whole place is worth a visit if you're out that way.

Does anyone have more information on these? Thanks!

The PCBs and backplane in the last photo are not standard 380Z boards. The 380Z 
doesn't use edge connectors like that, the boards just slot in guides and are 
joined 
by a 50 way IDC cable (which also carries power (!)).

To me this looks like an RML case that somebody has put an S100 backplane and 
a few boards in. I don't think it's an RML product (but would love to be proved 
wrong).

That's interesting... the case is typical of an early machine (later,

I am NOT interested in another, but, 
If you are there again soon, start with a quick look at the connectors in 
back.

It should have an FDC board, with a DC37F
It should have a video board, either:
CGA: DE9F, RCA F 
or  MDP: DE9F, DB25F (printer port)
Any other external connectors are added board, maybe IBM, maybe 
aftermarket.


That's almost all that you can tell without opening, unless it has certain 
other deviations from usual, such as a DB25 block-off and/or a round 
block-off on the back panel, or a white power switch, etc.



If/when you open it, the first step would be a detailed inventory of any 
OTHER expansion boards, followed by a glance at the on-board memory - 
early machines had four rows of 16K RAM; later used 64K RAM.  Original 
drives were Tandon TM100-1, followed soon thereafter (DOS 2.00) with 
TM100-2.  Original power supply of 5150 was 63.5? watts.  Some of the 
early power supplies were black.

RE: Reforming capacitors (technical description, not politics)

2015-07-31 Thread Eric Smith
Time to reform is to a first approximation proportional to the rated
capacitance, rated voltage, and the length of time that the capacitor has
been unpowered. However, there is still a lot of variation. I've had a few
40-year-old capacitors (unused for at least 30 years) that took less than
two hours tp reform to 135% of rated voltage, but others of the same
ratings that took more than 48 hours.

I usually use a lab power supply with adustable current limiting. I adjust
the voltage in increments of 1V, and set the current limit to a different
computed limit for each voltage increment so that the maimum power (PS
current limit setting * PS voltage setting) doesn't exceed a value believed
to have no risk of damage to the capacitor.

(This is basically the PDP-1 capacitor reformation procedure devised by Bob
Lash, except the voltage increments were 0.5V.)

At each voltage increment, the leakage current starts out higher than the
PS current limit, so the actual applied voltage doesn't rise to the PS
voltage setting immediately. As the oxide grows, the leakage current goes
down, so the voltage rises. Once it hits the PS voltage setting, the
voltage stays the same, but the leakage current continues to drop. I leave
it there until the leakage current stops declining (no further reforming
occurring), then go to the next voltage step.

With the few capacitors that wouldn't reform, at some voltage setting the
leakage current leveled off at a value higher than the maximum rated
leakage current. In some cases the leakage  current declined some but then
started to rise. When thag happens I conclude that thr capacitor has a
fault and cannot be reformed.

I usually use an lab supply that can be controlled over HP-IB or serial,
and use software to automate the process. The software sends a text message
to my phone when the process has completed or failed, and logs a fair bit
of information to a text file.

Good news, everyone. ;-)

I found the hardbound volume in question, and it does have a very

not sure this is the +exact+ article I had in mind when I raised the

But happily, I did a little searching and it turns out that the entire doc
is available online via Cornell U and Google books. How cool!

Here's the link: http://babel.hathitrust.org/cgi/pt?id=coo.31924004669861

Take a look at Section 9 for the primary capacitor articles. Meanwhile,
I'll keep my eye out for any other docs, I have a hunch there's another one

David,

>From the slides you posted it looks like you have some kind of automated set
up. Can you explain what you have there? The limited reforming I have done
has been done manually. I also notice that you reform over quite a few
hours, but those are big caps. Not sure I have seen any suggestions over how
long to reform for, and whether it is a function of the capacitor's nominal
capacitance.

Thanks

As a matter of fact I assumed that you'd intentionally let it through to give

effective in any case.

Nah - I believe that pretty much the most egregious thing one can do IMHO is 
take a private email and post it publicly. I'd pretty much never do that 
(except in very unique circumstances - if at all - and even then highly 
redacted), but apparently he had no such qualms as what he posted (with his 
vitriol at the end) was a private email I had sent him. Ah well, water under 
the bridge.

Back to classic computing :)

When I saw his next (and last post), I dug further. His email was on a

old "two lists joined at the hip" was configured. So I had to manually
remove him from the whitelist, even though he wasn't subscribed. My
Apologies for the oversight, but I believe it is fixed now.

Be advised that there is always a chance he's still subscribed under some
other unknown/non-descript email address. I'll weed them out as they are
discovered.


Well, that one let us know what sort of guy we're dealing 
with, here.  Seems your deletion of this member was VERY 
deserved!

... Which also may well not be RML original. The 380Z has a regulated PSU, 
S100 has separate regulators on each board and an unregulated PSU.
