I can't help you specifically but I note that that tape would've held some posts
from mid-1990 and want to wonder out loud:
Wonder if the same posts were on the "Usenet CD-ROM's" that were sold (or
maybe just discussed) in the early 90's.
"Sterling Software" is one name associated with that but I also remember a
Vancouver BC based company doing similarly.
Likely I just replaced an unreadable tape with an unfindable CD. I have no idea if the
"sell-usenet-on-CD's" ever actually sold any.

I remember the company in Walnut Creek, California selling them. When I was
stationed on an Aircraft Carrier between '94-96 I'd buy at least some of
them, and put them on the laptop I had running Linux. Mostly I bought the
Linux CD's, but I also got a few others like USENET, CP-M, OS/2, and others.
All my old CD's from that timeframe are something else I should probably get
put together in one location. At the moment they're spread throughout the
garage, with probably one or two in my Office.

I have been working on collecting Walnut Creek CDs for CHM. I don't recall
there being Usenet CDs from Walnut Creek, though.
Jason at cd.textfiles.com has been doing a great job of CD preservation. Had
a chance to talk to him when he was out here a few months ago.

There were two main companies I was buying from, if it wasn't Walnut Creek,
it must have been the other.

Definitely an invaluable resource. I was able to find a most interesting
2nd Volume to one set where the first Volume was one of my very first
CD-ROM's, that I purchased in Washington DC.

Sterling Software was at least successful giving away piles of these CDs
at conferences, as I got a couple (which are buried in storage somewhere).
I seem to recall that DejaNews (maybe after it got folded into Google?)
was at one point asking for people with those CDs to contribute copies
so they could complete their coverage. I know I tried to participate,
but can't seem to find that email now...

Help Us Complete the Usenet Archive
Google is attempting to compile the most complete archive possible of Usenet posts, and we
need help doing it. We are looking for archives pre-dating 1995, in particular the
"NetNews CD Series". These CDs were commercially available through Sterling
Software and later through CD Publishing Corporation between early 1992 and 1995. The CDs
were released separately and each CD covers approximately a two week time span. We've
already located NetNews CDs #6 - #31, which cover March 92 through January 93.
If you own NetNews CDs or if you know somebody who does, please contact us at
groups-support at google.com. We will pay a finder's fee for any NetNews CD we do not
own already. Thanks for helping us build the most authoritative Usenet archive online.
Thanks,
The Google Team

This really sounds like something that should be "preserved somewhere." I'm
starting to add more archives to the gopher server and having a Usenet
archive hosted on Gopherspace seems highly appropriate, actually.

I want to add some RF shielding to a new addon device and without having
to go with bent aluminum shielding, I thought I'd go the old Apple ][
route and get some spray on RF coating, anyone know where I can purchase
that kind of material in a spray can form?

You want nickle impregnated spray paint...

GC (aka, General Cement) used to offer it too but it doesn't look like
they do anymore.

Thanks, that'll do the trick and I found a distributor right up in CT
not far from me....

When we were building cases from structural foam, we'd have the paint
place spray the inside with metallic zinc, which did the job.
I think this stuff is the rattle-can equivalent (there are many
brands of the stuff):

Which do you think is more effective - Zinc or Nickle flake ?

Copper- or silver-flake, but I suspect that zinc or nickle are about
equivalent for RFI shielding.

Ah... the solid metal enclosure that you didn't want ;-)
Any sort of (spray) paint on shielding is a compromise. There are
challenges in getting it bonded well to the actual ground and in getting
a uniform and consistent coating that maintains the shield.
You really need to know what the emission levels are before you paint
it... and then again afterward... to see if you've made a noticeable
(or acceptable) improvement. The whole situation is then also frequency
dependent... so again, you need to know where the hot spots are and
address those accordingly.
Are you making a thing you are going to sell and needs FCC part 15 (or
other authority) compliance or are you trying to fix a one-off project
that is interfering with something?

Good points. We did the zinc coating as the last step in getting VDE
certification (tougher than Part 15). We'd already wrapped just
about everything in sheet-metal shields with bonded (spot-welded)
grounding braid,, but some RFI was escaping and the zinc spray took
care of it. I've seen it on the inner sides of other cases as
well, but I don't recall that it was the sole line of defense.
