Look at what Al Kossow has managed to do with
bitsavers. Yup, a lot of
"collectible" documents have undergone spine-ectomies, but had he simply
rented a warehouse and shelved everything, I'd guess that none of us
would have heard, much less benefited from, bitsavers.
In the real world "good enough" trumps
"ideally."
Exactly. You can collect paper of marginal historical
value faster and with greater volume than you can afford to store it.
There is absolutely no way that I can afford to keep the paper that I
currently have, and have been working on triage and recycling for several
years now. Bitsavers is just under 100gb right now. That is a LOT of linear
feet of paper!
I've been scanning hundreds of magazine dups at CHM for the past two months
just to OCR and index the text for research on the exhibit we are building.
I'm not concerned about the images of the ads (including the WPS ones). We
approached other institutions, and they were not interested in the paper.
The spines were cut, and have been scanned using a high speed sheet feeder.
They are worth more to researchers as indexed bits than as pallets of dead
trees.
Newsprint is an even worse problem.

An IBM729 Mark 5 tape drive grabbed the data for NASA.
I presume that this implies NASA had tried and failed to find such a
drive via IBM?
Good to see that some old tapes retain their data!

:?) I was about to post that link, too.
I suspect that the museum might welcome contacts from anyone with
experience of restoring such elderly kit - it sounds from the news
story that they are rather daunted by the task!

Golly, why use an IBM pinch-roller drive (I remember the 729-IV on
S/360 gear) when a CDC vacuum-capstan drive would be far gentler on
the tape? A modern streamer might be gentler still.
Just curious about the selection of the drive.

But it's just a plain old 1/2 inch tape drive. And Fortran wouldn't care about
the specific model... In fact, if it's Fortran it could be easily ported to GCC
Fortran and run with any convenient 1/2 inch SCSI tape drive on a PC...

Best yet, they could just ask NASA for the data. EVERY BIT OF EVERY
MISSION is archived and (mostly) available online. Some of the more
obscure data still needs to be pulled of WORMs. Mike at RCS/RI says
DEC WORM drives.

That's what I thought. I can't imagine that NASA would consign

Minor correction - most is not online, but it all can be ordered and a
tape or CDROM written.

NASA would consign
mission data to the dumpster, particularly given the (comparatively)
small number of missions.
I think this is all blown up from a few researchers over the years
that have been looking for the original telemetry tapes. At least one
group recently has been looking into something with anomalies in
signal transit time or something, and the raw telemetry data could be
distilled to get some real data. NASA, however, did not keep many of
the telemetry tapes - but they never intended to keep them. As soon as
able, the tapes were read and decoded into the data they wanted from
the probes and eventually made public to the zillions of scientists
that were foaming at the mouth for it. Keeping the telemetry tapes
would be similar to Jay archiving this list with all the TCP/IP
headers and junk.
I think RCS/RI has one of the original Viking mission tapes kicking around.

40 years ago, when I was working at the National Space Sciences Data
Center (building 26, Goddard Space Flight Center), tapes, decks of cards,
and Fortran source were going missing on a regular basis, and some of the
people managing the tape collections felt that only the most recent data
was worth keeping. On a few occasions, I was handed "scratch" tapes to
use for output and transfer to plotters that had important sounding prior
labels on them. "I'm sure that there must be a few more copies of that
data around somewhere."

I remember chatting with a guy in the next office over who was on the
MDSF project (remember Skylab?). He quoted some fairly astonishing
numbers to me on the amount of the raw telemetry data that was
actually discarded in processing.
Was any of the software from MDSF ever archived?

Memories in IT are short.
Tape drives (let alone tape /streamers/) are an archaic, historical
curiosity now. You have to be a veteran of the IT industry - that is,
around for a decade or more - to remember primitive tech like DAT
drives. Most such people are now so senior they never handle kit any
more.
Tapes are history.
The slight snag being that there's nothing to replace them with. Now,
a common solution is a virtualised tape library - a rack of disks in a
RAID pretending to be a tape drive with lots of cartridges already
loaded. This probably talks to the server being backed up using iSCSI
- SCSI packets encapsulated in TCP/IP and then sent to the storage
server over Ethernet. Layer upon layer upon layer of emulation.

Not hardly. They've finally got stiff competition in off-site

We have a bigger taller cousin, two very large conjoined cabinets with a
scary robot arm, a few drives, and a shedload[1] of LTO4s. If you want
to see what the previous generation looked like, see the cover and page

This is the backup for our mirrored pair of filers.

After reading the article, I get the impression that it is at the
stage of, we have some tapes that were recorded with data that have
been kept in controlled conditions for 2 out of the last 35 years, and
we have located a drive designed to read the tapes. If there is still
data on the tape, and it can be read by the drive - that is something
we will find out in mid Jan!
