> A floppy disk can hold a maximum of 1,457,664 Bytes. Ahhh, the kids of today. Having started with the 133mm 1541 on the Commodore 64, with its double-your-disk-capacity-with-a-hole-punch, and then onto the Amiga with its 89mm disks of 880KB capacity, and then working on Honeywell front end processors in the early 1990's with their 203mm disks with around 240KB ...

Ahhh, you kids that started with the Commodore 64/1541 and 170k of capacity. I started with a TRS-80 Model 1 with a Shugart SA-400 drive connected to an expansion interface. 85K capacity.

  Well, I started with a VIC20 and a tape drive -- but in terms of floppy disks, that wasn't until sometime after the C64 arrived. My neighbour was a developer working in assembler, producing games for the TRS-80, and my first 'real' (as in monies being handed over) job was as a tape-copying, paper-folding, inserting-both-into-a-ziplock-bag monkey.

    The original comment was regarding floppy drives so I mentioned the first computer with a floppy drive I used. The first computer I would have used was my father's Heathkit ET-3400 microprocessor learning system in 1976. That required each time typing in the machine code for the high/low game I played on it. The TRS-80 Model 1 was purchased a year or so later and originally had a tape drive.

RISC OS is the original OS for the ARM chip, and the Raspberry Pi can run it natively. It apparently doesn't support floppy disc drives (the Pi lacks the interface, and USB drives appear like USB memory sticks to the OS). If it did, the ADFS (Advanced Disc Filing System) would format discs to 800 or 1600KB. https://en.wikipedia.org/wiki/Advanced_Disc_Filing_System https://en.wikipedia.org/wiki/Advanced_Disc_Filing_System (PS, it's 90mm. Odd that even outside the USA we said 3½ inches.)

Still have my doubled C64 floppies, of which some were horribly scarred by the big blunt scissors I started out with. You could also convert Amiga floppies from single to double density by adding a hole, giving you 1760kB. I didn't have money for quality disks, and found that "punching" the hole with a hot soldering iron lead to less problems than using what was probably the wrong bit in my dad's drill.
