First of all, I think that the latest Norton Utilities are soooo
bloated, they possibly won't even run on a damaged computer. High-res
pictures of your computer components are the latest thing you need when
you can't find a vital data file. For example, what good is it to have a
data recovery program you can't run if you just formatted your hard
drive?
That said, I think NU is a good tool, but Spinrite is still better than
NDD.

This is a case of the law being intended (originally) for quite
different purposes. The story behind it is that the Nevada Legislature
has an email system where the public can send comments to the lawmakers
when the Legislature is in session (every other year for a few months).
It seems last year someone flamed one of the senior politicians, he got
pissed off, claimed it was racially motivated hate mail and tried to
outlaw flaming. Someone (the state attorney general) pointed out to him
his proposed law violated both free speech and right to petition for
redress in the Constitution, but he wouldn't back down and withdraw his
bill, so to keep it legal it was changed to an anti-spam law, and in
theory flame mail can be legally defined as spam too. No one expects
this law to ever be enforced.

USD five ?
I don't think ths law will have any impact - very spaming friendly.
Just done to get votes but avoide any change.
Yes, I have returned. Lord Almighty, what a haul!! I can say with
confidence that I definitely tested the maximum load specs for the (rented)
Ford Windstar minivan. Every time I went over a good bump, the rear springs
-almost- bottomed out.
I'll be updating my web page soon with the gory details. Suffice to say
I've got more than enough to keep me going, project-wise, well into next
year. Among the more 'classic' items in the haul were a Kennedy 9100 tape
drive installed in a nice 5-foot DEC rack, and a box full of 9-track tapes
containing mostly DECUS RT-11 SIG libraries.
Tony, I know you'll get a kick out of this. I also got hold of another
11/44 CPU box, loaded with cards (including a Unibus UDA50 disk
controller). Between that one and my current unit, I should be able to get
the power supply going AND fix the broken one for a spare!
Since I'm not heavily into RT-11 (yet), I'd like to offer the RT-11 SIG
tapes to whoever's interested and willing to pay shipping. There's about
six or so, maybe a couple more.
And would you believe I'm already planning next year's run?
I know I'll see at least some of you at VCF in another couple of months.
Until then...
Banzai! ;-)

Majorly true.
I worked in pharmaceuticals and though they didn't use super clean rooms
(class 10,000 worst case) the equipment was under a laminar airflow curtain
with a flow of 100 linear feet per minute and the air under there was class
100. The air flow was obvious ly of the the machine then into the room
where super clean was less important.
< I would have thought looking for backscattered light would be more

The air flow and the sensing area cross section are important. Using a
light source like a laser is helpful in getting the backscatter brighter.
This is the problem of how many Angeles can dance on the end of a pin.
You build a clean box and use a good HEPA filter. With 100-200cfm of
incomming clean air once the dust in the box has been blown out it will be
clean especially if gloved hands are the only thing inside.
I'e heard a lot of "good luck", "it will not last" and "too dirty" from
those that haven't. I've done it, when RD53s and 54s were in desperately
short supply here and it does work without the clean box with some care.
Obvious tricks like wearing nylon gloves to avoid finger prints, a canister
of dry air to blow things off and keeping the unit covered when possible
all reduce risk.

< I'm not sure what that means, but I assume that the servo surface

< possible to realign the thing with another servo platter?
First it depends if the servo is embedded or dedicated platter or stepper
(or other absolute positioner).
For dedicated platter one head is assigned as the servo head and since they
are all mechanically one assembly the rest just follow along. Now if a
platter is changed it's data may be offset relative to the others. Same
thing is true for replacing a head as the RELATIVE alignment between heads
is disturbed. This case I believer the disk can be low level formatted
and reused but existant data may be lost. If servo information does not
exist (DeMIL'd drive) it's likely good for parts as servo tracks are hard
to regenerate.
If it's embedded servo per head each head as selected will follow the
selected track servo signals and making relative head alignment less
critical. If the servo is blown there is no way to regenerate easily.
For cases of absolute positioners like older ST506/412/225/251 (and a swarm
of others) drives getting alignment to cylinder 000 and beteeen heads would
be critical for complete data recovery. If the drive is to be reformatted
however a bulk erase and reformat will establish new tracks in some cases
and make a mess in others.
In the case of removable pack drives that is a totally different can of
worms though simpler as they so have alignment procedures for field or
depot use.

Doug, if you indeed do go to Munich to see the Deutches Museum I suggest
you set aside at least a _full_ day to see only a couple of sections or
several days to see most of the museum. Roller skates or rollerblades would
be of great help to see more in less time<g>
I'm the type of person who studies a museum and have spent two to four
hours in each of the few sections I've visited during the three different
visits to the Deutches Museum. As Hans just said in a previous msg in this
thread, the computer section is indeed about 12,000 square feet. Loved it!
Seriously, I do recommend seeing the collections at Deutches Museum to
anybody who may visit Munich. Something for everybody. Check out URL:
http://www.deutsches-museum.de/dme01.htm if you're interested.
Have fun in Europe,

Yes, dual head positioners on both sides plus four twenty pin
connectors on both sides as well.
David is correct as well, I have confirmed this HDA is from an IBM
4381 mainframe and uses a 3880 controller. Does this HDA have a
lineage that goes back to the IBM Ramac? Any idea when this HDA was
introduced? It certainly will make a great paper weight.

Good Lord... unless I miss my guess, that's from a System/390 mainframe!
Let me guess... dual head positioners on either side, yes? And big
connectors with about a zillion pins?

Thanks Doug.
Now I know - I have to have a MAD1 - I _must_ have any 80186/88
system ever build - just a obsession - maybe because I like
the PC-D a lot .)
