Before there were CD's in PC gaming their were this thing called a Floppy Disk and it required at least some sort of windows command prompt command in order to install or even play the games every single time you wanted to play it. It was not like modern PC games where all you have to do is click on the icon. instead you had to type into a command prompt called MS/Dos
There are 2 types of floppy disk. the original floppy disks or the late 1980's were big, flat, and square and flimsy and could not hold much data, at all, compared to today data standards,
Then there were the harder, smaller, less flimsy floppy disks of the early 1990's and they worked vary similar to the old, larger, and flimsy floppy disks. the newer harder and smaller floppy disk and held more data a little over 1 megabyte, I think.
however both floppy disks and floppy disk drives drives ended up on both Apple and Windows PC's of the 1980's and 1990's.
Does anyone remember the buzzing sound difference the big and smaller floppy disk drives? if not then I'll tell you my larger floppy disk drive had a vary low pitch buzz almost like a fart while my smaller newer floppy disk drives still had the buzz but it was louder and more high pitch. this was back in early 1990's
