Where do you get “several hundred megabytes”? The article says that it can load from a floppy disk. The largest of those IIRC was the 1.44 meg 3.5” floppy.
Perhaps I wasn't being clear in context. I was referring to the various iterations of the Microsoft Windows operating system. My recollection is that it is several hundreds of megabytes. I don't even know how big is the latest version of it. I quit upgrading after XP.
3.5” 1.44M was technically a ‘flexy.’ [There was also a 2.88M high density version.] The biggest true 5.25 inch floppy was a 1.2M high density version, introduced in 1984.
Nope. I had a 2.88 Mb floppy drive. They never really caught on, because by the time they came out, CDs were starting to really take over.
