When a 5Mb drive was big.

I like this bit:
In 1976, Shugart Associates (later Shugart Technologies, then Seagate Technology) joined forces with Wang Laboratories to produce the first 5.25-inch floppy drive, which was used for years in early IBM and Apple personal computers. Why was the 5.25-inch disk size selected? Interesting story, as Jim Porter tells it: "Well, the guys from Schugart and Wang got together to discuss the project, and they went out to a bar one night for drinks. One of them looked at the cocktail napkin and said, 'That's looks like a good size for the disk we want to make.' So it made it into the instructions for Shugart back in the Bay Area to make a floppy disk drive the size of a cocktail napkin—5.25 inches square." All that for 218K capacityLast edited by Sysman; 28 February 2013, 17:21.Behold the warranty -- the bold print giveth and the fine print taketh away. -

And I have worked with Fujitsu Eagle drives (slide 13). If I remember correctly you could format them to look like 2 RM05 drives, might have been 3 with later models.Comment

Our 1st PC had a 20mb drive.
It cost us £1400..."I can put any old tat in my sig, put quotes around it and attribute to someone of whom I've heard, to make it sound true."

That seems to be engraved on my soul.
Double sided were 500k, but you needed a different disk drive to use them.
If you wanted to use SS & DS, you needed a special disk drive that had two index hole detectors.
Wonderful piece of design.
1.2M was the size of the HD 5.25" floppies on the AT.
PC XT used 320k DSDD disks, then 360k (extra sector).
Not sure if the PC used SSDD 160k disks.Comment
