Does anyone know anything about a Tullamore/Victoreen SCIPP 1600? I
have found one of these, and it appears to be some sort of computer-
based "analyzer" from the 70s, but I can't find much using google,
besides references in papers to having used one.

Pretty sure I've seen the sources already on the net.
Pretty sure I also have them somewhere.
I definitely have TECO-8. And it was available from the DECUS library in
the past, but that was many years ago by now. (That's where I got it from.)
Maybe you should start looking at our own ftp archive? :-)

As I didn't end up getting the OMR-2000 that ended on ebay yesterday,
I'm still sort of looking for a punch card reader, preferably something
that's functional, and that won't take too much effort to connect to a
machine I already have (eg, one of the surplus Documation? 2000 election
units).
I don't have a big budget for this, or any REAL need, but I do have some
cards I'd like to archive at some point from Purdue's old CDC gear, and
of course who doesn't need to have a punch card setup laying around??

Pretty sure there have been one or two in the DECUS archives. But I'd
have to make some searches to locate it. But you can perhaps do that
yourself on trailing edge?

Hey,
I watched the following auction, just for curiosity:
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=290357667738
Now it has ended. The 12 tapes went for $430!!!
None of those has an original DEC label. Is there anything extremely important on them?
Or are DECTape reels rare, uncommon and valuable?
Any ideas?
Regards,
Philipp

Hi, All,
Some of the equipment I have has been through the wringer before it
got to me so I have a couple of items of unpainted, galvanized steel
where the galvanization is gone in patches larger than your hand and
the steel underneath has oxidized to black (not so bad) or red (not so
good). At the moment, I'm dealing with a single-board-computer "base"
and a semi-custom rack shelf that both need some help. I know I can
treat red iron oxide (rust) with naval jelly, but then I still have
bare steel with no galvanization. I'm not expecting to get a
cosmetically perfect item, but is there a good way to restore/protect
things like this, or should I just expect to paint the entire item (it
would look strange to just paint the formerly-galvanized area).
Obviously, descaling, sanding and painting is one way to deal with
this. I'm looking for possible alternatives.
Thanks for any suggestions or pointers,
-ethan

Looks like the message was eaten.
The pdf is on bitsavers for you to take a look at.
CHM hasn't issued a press release about it since we're still doing things
like trying to convert the interleaf formatted manuals to pdfs and are organizing
what we have.
What HP actually donated was materal from about the last 10 years of the product's
life (RTE-A, mostly). The earlier code is coming from other holdings.

I have more or less fixed my Teletype Model ASR33. The pieces are out of
alignment, but overall it's minimally functional.

Everybody has to draw boundaries over what they're gonna try to do, and what they not try to do.
I think it is reasonable for the Catweasel people to say they only log transitions on the floppy and that they don't try to do anything else.
Other people can pick up where their expertise comes in.
Details of file formats of every obsolete 12-bit OS is not something I would trust the Catweasel people to do in fact.
I know of floppy disk formats that in fact are not in fact fixed sector size, they are more like a cassette tape filesystem where sectors vary in length as necessary.
Remember Al, that's why we go for image files as the actual archive with everything else just an interpretation or display.
