I am in need of the HP-UX System Security manual from 1989. I don't know
if that is the exact title but it's what I was given.
If someone's got it then please come forward. There is a bounty for this.

So is this the power supply all those whiney people were bitching about
NASA trying to put into a Mars probe? They were all afraid the probe
would explode during launch and be ground zero of a nuclear blast (or
some other most likely vagely based on reality doomsday outcome activists
are notorious for).

Knowing NOTHING about radioactive material (other than its amazing what
simple items will set off my fire department's old geiger counter)...
would an explosion really pose a health hazard? Are we talking about
enough of a quantity to cause an issue (I don't know how deadly it is, so
I don't know what kind of an airborn PPM is needed to be a problem).

Hi
One should note that most switching supplies are happier
with an additional 20% voltage. Linears get hotter with
excess voltage.

For the few of us on the list that are idiots (ok, fine, just for me
then), what is RTG sourced power?

After seeing the mission status report on Vyger, I'd have to revise my
previous notion that I didn't accept it as an answer. Since it is still
sending data, and we are still receiving it, and it is still carrying out
its original mission (ie: it isn't doing it simply because it can't be
turned off, but rather is doing it because we WANT it to do it regardless
of our ability to shut it off).
I'd have to say that I now DO accept Vyger as an answer. So the question
is, when was it launched (1977) and is there something older in regular
use (I would think so).
But this also brought to my attention something I had previously not
know. That Voyager 1 and 2 were both launched at the same time. I had
always thought 2 was years after 1 (I thought 2 was late 70's, and 1 was
early 70's). I'm not sure why I thought that, maybe it was because it
took a different course and was more recently in the news sending back
data about the outer planets.

I think RTG stands for "Radioactive Thermal Generation" or something like that.
It is a hunk of plutonium that, on its own, glows at a high temperature.
Since the temperature of space is near absolute zero, there is a large temperature difference.
A relatively simple, dependable thermocouple generates electrical power from this temperature difference,
making a really long-lasting, dependable battery -- but not of the sort you want in your kid's toys :-)

Hi
For my DSP experiments, I got one of those "SoftModems".
It had a A/D-D/A, ADSP2100 Analog Devices DSP and RAM to load
the programs into. It only cost me $75 when new.

Hi
You must know something about the military that I don't know. When
I was in the military ( middle 70's ) we were still using some pieces
of gear that were made during ww2. The military often doesn't replace
something until you can't get replacement parts any more. In some
cases, even then, ways are found to keep them running.
They do get a lot of new gear but that is usually to add function
and not to replace.

Voyager Mission Operations Status Report # 2003-03-14, March 8 Through
March 14, 2003
Command Transmission & Verification Operations
Voyager 1 command operations consisted of a command loss timer reset on
03/11 [DOY 070/1555z]. The spacecraft received the command.
There were no Voyager 2 command operations during the period.
Sequence Generation Operations
Continue sequence development of CCSL A047 and B119 mini-sequence.
Data Return Operations
Voyager 1 Data Processing and Operations:
There were 79.1 hours of DSN scheduled support for Voyager 1 of which
2.5 hours were large aperture coverage. There was one real-time change
made on 03/11 [DOY 070] when 1.3 hours of DSS-25 support was released to
Ulysses. The total actual support was 77.8 hours of which 2.5 hours
were large aperture coverage. There were no significant outages during
the period.
Science instrument performance was nominal for all activities during
this period. One frame of GS-4 data was recorded this week. The AHELI1
cyclic for recording additional GS-4 data was enabled on November 17,
2001. A frame from this cyclic was recorded on March 8. The EDR
backlog is 23 days.
Voyager 2 Data Processing and Operations:
There were 73.9 hours of DSN scheduled support for Voyager 2 of which
18.0 hours were large aperture coverage. There were no real-time or
schedule support changes made or significant outages during the period.
Science instrument performance was nominal for all activities during
this period. One frame of GS-4 data was recorded on March 12. The
PRA receiver recovered from it's 84th POR event on March 11. It has
been 393 days since the last POR event. Twenty-six frames of GS-4 data
were played back on March 12. Approximately 96.95% of the data were
recovered. The EDR backlog is 23 days.
Flight System Performance
Voyager 1 performance was nominal during this report period. Activity
included an ASCAL on 3/12 (DOY 071).
Voyager 2 performance was nominal during this report period.
Activities included a PMPCAL on 3/11 (DOY 070), X-Band high power and
DTR playback on 3/12 (DOY 071), and turning ON Gyros B/C on 3/13 (DOY
072).
