It's not done by grinding, but it can be done by dissolving the epoxy
encasulation in fuming nitric acid. I found some good descriptions of
the process several years ago while researching the security problems
associated with Mondex.

What do you use in this thing? I've got a VAX 4000/300 with a TK70,
but it didn't come with any media and I'm wondering what I should be
looking for to feed it :)

I know this is a late response (I didn't see your posting until now), but, yes,
I'll take a handful (dozen?).
I find that I not only use these PCMCIA ethernet/modem cards...I use them *UP*
and they occassionally die on me. Still, I find that using a couple of old
Pentium class laptops for my basement web and email servers is the way to go.
(This topic was a recent discussion item a month or so ago.) They come with
their own UPS (battery pack) and they are quiet, and draw very little juice.
So, yeah, I'll take a stash of potential replacement network cards, dongles
would be nice. For some reason a 24/7 situation with these kind of PCMCIA cards
tends to wear them out over a 6 to 12 month span. I just had to replace one a
month ago. A handy stash would be very welcome.
Let me know if you were able to snag these cards, and we'll work out pickup
arrangements. I'm actually in Utah County.
Thanks.

Heh, if you need TK50 tapes, I have a slew of them, just dug up (unboxed
and put with the rest of the takes) a brand new VMS 5.7 tape. Probably
have a few CompactTapeII's in there somewhere too. Also have boxes of
90M DAT tapes, all free to anyone who wants them (heh, and 90M DAT's,
you're talking 100's of them).
Also have a few external SCSI TK50 drives, I think 2 or 3 I could stand
to get rid of if anyone is interested.
Oh yeah, and have a couple of DecStation 5000/125's to get rid of, if
anyone has any interest.
And for PC's, an Everex Cube, 486/33(?) EISA box, I think loaded with
like 6x600MB 1/2-height SCSI drives, but I'd have to look.
Not looking for money for anything, just trying to find good homes for
some stuff I haven't used in years.
If you need a a few TK50 carts, I have some.

Oops, sorry about the previous reply. Hit the wrong button!
There is nothing added in that reply ...

Your help is much appreciated, Tony!
But, if you know what and why to do something, a swap is not a crime.
Of course, you swap only *one* board. If that solved the problem, you
can label the swapped board with a note of the seen symptom.
I say that it solved the problem, not fixed it. That's for later ...

That's what I'd do, the diagnostic output is descriptive enough. However,
... I don't have the printset of the RK611 :-( and it is not on bitsavers :-(
I'm afraid I will have to put the RK07/RK611 on hold for a short time ...

Addendum addendum: apparently the DLT tapes were left in the library
as an oversight and they are not being offered...

Of course, the free version runs on classic NeXT hardware!
Not affiliated, but I have a pretty high regard for some of Frank's
other work which I use on my NeXT.

Hi all -- Sellam fixed his web site (there was a drive crash) -- and so VCF
East 3.0 exhibit registration is now open. If you signed up for an exhibit
already, you'll have to do so again. Sorry. The link is
http://www.vintage.org/2006/east/exhibit.php
For those who might be wondering, the reason I'm making this announcement
instead of Sellam is because I run the local club hosting this edition of
VCF. After all my newsletter just isn't * enough * extra work each week!
;)
A refresher: VCF East is no longer in the Boston area. It moved to the
InfoAge Learning Center (http://www.infoage.org) located in Wall, NJ, which
is on the NJ coast about one hour east of Trenton, south of Newark, and
north of Atlantic City. It's very easy to reach from the I-95 corridor or
>from the west via Pennsylvania. This edition is a ONE-DAY event (Saturday,
March 13) but it will be a loooong day.
The prices aren't yet determined but they will be fair and in line with past
rates.
