“The Air Force completed a replacement of the aging SACCS floppy drives with a highly secure solid-state digital storage solution in June,” Sounds like flash drives. Perhaps even USB.

EPROMs, and the UV lamp is locked in a cupboard with a highly secure combination lock

The sources I could find say that they didn't replace the computers accessing the data. They are still IBM Series/1 [1] machines. So whatever is being used, there has to be some kind of floppy (or tape, etc) emulator in front of it. It's likely the floppy drive in question was an IBM 23FD "Minnow"[2]. The capacity and timeframe matches up. [1] https://en.wikipedia.org/wiki/IBM_Series/1 [2] https://historyofinformatio…

Well, they will also need 8" to 5.25".

This might be controversial, but I don't see anything inherently wrong with non-networked computer systems using old tech. I think a lot of tech nerds see the tech as the sole capability of a system, ie 2x the clock speed is 2x the capability, but that's just not how real world systems work. The biggest issues seem to be getting replacement components as systems age or new systems are purchased (like with the scaling…

Nothing lasts forever. Things need to be fixed and patched continuously, (especially since floppy disks aren't exactly known for their durability) and at some point it's just not cost-effective or even reliable to maintain the old tech anymore. Eventually, a non-networked system will have to be upgraded with newer hardware.

8" was the standard size before 5.25" became the norm. Which happened because of the IBM PC using them as standard.

And just to point out, the logical capacity of those disks increased with each physical reduction. Nearly doubling each time. (The best 8" disks had about 1/2 of the capacity of the worst 5 1/4" one, and the best 5 1/4" disk had about 1/2 of the capacity of the worst 3 1/2" one.) I guess even if IBM didn't put it on the PC, everybody would migrate into 5 1/4" disks on almost the same timeline. Those changes were very…

The standard 8" floppy by 1980 was 2MB, 5.25" never beat that, and 3.5" only beat that technically, 'ED' 2.88MB, LS120 and SuperDisk were all very rarely used in reality.

What's funny is that the floppy discs they used weren't the 3,5" hard ones people remember from the 90's (the save button icon) but the old 5,25" ones that were actually floppy. That was some ancient shit.

Weren’t they ever bigger than that? I have a vague recollection that it was some sort of 8” oddball format. Maybe even a one-off?

From the subhead of the article:

> The Defense Department has transitioned away from a 1970s-era nuclear command and control system that relied on eight-inch floppy disks.

Is it safe to breathe that dust? I'd like the smell of nuclear floppy in the morning.

Depending on how the microplastics were disposed of, you may already have fragments of the nuclear floppies in your bloodstream.

If you ever have feelings of self doubt remember you are partly made of nuclear bomb code plastic

You could use Stacker to get a bit more :-).

8" was the standard size before 5.25" became the norm. Which happened because of the IBM PC using them as standard.

Even before then, 5.25" was popular among personal computer makers, such as Apple, Radio Shack, Commodore, Atari, and Osborne. (Though the TRS-80 Model II used 8".)

I worked at a place that bought 5.25 inch floppy drives on ebay since they can't be bought new any more. Seems like a huge supply chain risk.

Apple, Commodore, Osborne and others were using 5.25" disks at around or before the IBM PC came into play. IBM used 5.25" drives in the PC because they were inexpensive, reliable commodity hardware, much like the rest of the IMB PC.
