Like US launch codes? :) Doesn't the military still use 8" floppies for
some operational systems they don't want to replace?

It might be just me, but those look like they?ve got great big holes cut in them?

I didn't see any holes. And, yes, 8" floppies are SUPPOSED
to have a big hole in the center.
Anyway, the labels indicate they have diagnostic programs.

back, kind of like file folder tabs.
Don't think I've seen pouches with that before but probably intended to make it
easy to grab a disk by the pouch when they're all down in the box.
Look at the magnified view of the 3rd pic.

Ah yes, that makes much more sense. I can see it now.

I hope you get them. Cheaply.
And if so, please let us know if the data was recoverable. I have some quite old
floppies to someday get around to attempting to recover. Really curious to see
whether floppies suffer 'data evaporation' over time or not.
FWIW, years ago a friend of mine found some important floppies of his had all
developped mold on the magnetic surfaces. Which fouled read heads, making them
useless. We found that slitting open the covers, taking out the disks and
literally washing them in the bathtub with soap and water, drying, then putting
back in the covers, worked!

Disks of that time period tend to do well.
Some later disks didn't fare so well, such as Wabash, or Verbatim BEFORE
DATALIFE.

and sometimes gentle baking can help
(think food dehydrator)
I have encountered a lot of disks that were not stored exceptionally well,
that had developed difficulty turning in the jackets.
Rubbing each edge of the jacket firmly perpendicularly against the edge of
a tabletop, so that the jacket bowed out SLIGHTLY, often helped
substantially. Then you can usually turn the cookie in the jacket with
fingers through the center hole.

Back in the day, I was working with a group on a four-month project,
where the final version on 8" floppies of the (source) software was put
on display for a little celebration. Management sprang for bottles of
bubbly, some munchies and some T-shirts--and the department had a small
party.
What no one noticed until the next day was that the stack of floppies
had been soaked through with champagne, and put away for the weekend.
Monday arrived--and the disks were a sticky mess. Fortunately, the
treatment of washing and re-jacketing did the trick. But there were
some very nervous people in the meantime.
Needless to say, we made several backup sets and sent two of them off to
the vault.

Because a "make an offer" can carry some risks of OFFENDING the seller, if
they had thought that the value was not in the same general range as your
offer.
Not much known history with that seller.
If nobody else bids, then it will be cheap, other than the shipping (the
seller does not seem to know about media mail: "Computer-readable media
containing prerecorded information")

Just be polite and nice in your message with the offer, explain why it's a fair
offer from your perspective.
Al, why not offer $5 or $10, explain you want to try data recovery for bitsavers,
but the disks may well be unreadable.
It now has 5 watchers. Maybe they are all members of this list, maybe not.
I assume you are aware of snipe-bidding services? Some of those watchers may
be too, but you won't know till after the end.
I've used bidnapper in the past very successfully.

He will know if you tell him.

I made a higher offer than that, still no reply.
I've had very little luck making offers on auction items.
BIN is a different story.
I think eBay changed something so that making an offer on
auctions became a default or something withing the past
few months and it drives me crazy since 'make an offer'
in the past was always only associated with BIN.
It is pretty pointless, since you can't make an offer once
there has been a bid.

I know what the software on those disks is, because I have these floppies too (and the
system they're for). These are diagnostics for a 24-bit Honeywell 4500 process
computer (a successor to the GE PAC 4000 system; some pictures on my website:
https://vaxbarn.com/index.php/other-bits/654-honeywell-4500). I haven't imaged the
ones I have yet, but I will get around to it eventually. Mine are CDC branded floppies as
well, and the diskette drive that came with the 4500 was a Honeywell-labeled CDC drive.

I suspected they were GE-PAC related.
Ended up getting them, we'll see if they are readble
He would have made 5x more if he wouldn't have ignored my offer, sucks to be him.
