    Let's make this a thread of things that posters have just learnt.

    I'd like to start with this one:

    The British Airways Boeing 747-400 fleet, up to its retirement in 2020, used 3.5-inch floppy disks to load avionics software.

    A windows 10 installation iso would require approximately 3500 3.5" floppy disks.

    From memory, Win 3.1 was on 10 or 11 3.5 HD disks.
     
  6. I'm wondering how many word documents you could squeeze onto a 3.5 floppy disks - do you know? I'm guessing a few hundred to a thousand max

    That will depend on their size, plus there will be an overhead per document.

    An A4 sheet of plain text is about 2k bytes, so you could store about 500 A4 pages on a floppy disk. IIRC correctly War and Peace is under 2Mb in size.

    Not as many as you used to be able to.

    2 really. The 1.44 MB HD floppies when formatted could only hold about 1 MB.
     
  13. Where they only 1.44 MB?

    I've always had a problem with how coal was formed. I just cannot picture all those trees falling over & just laying there until something came along to cover them over. I've always wondered why there wasn't something that will one day become coal but isn't quite coal yet.

    I remember the storm that blew over a really BIG tree during my childhood, I remember it 'cos it was a fantastic tree to climb. The pathetic & decayed remains of that tree are still there all these years later . . . .

    I recently learned that back when coal was formed, fallen trees didn't rot away like they would today, because the enzymes, the bacteria, the fungi & the insects that attack fallen timber hadn't yet evolved.

    Ive also learned why I never got inside Julie Brewers knickers in '76, bumped into her & her wife whilst out walking last week :)

    Wrong way round. 2Mb pre-format, then 1.44Mb once formatted.
