I am 74. I got into computers in 1979 before there were any pc.
I am 74 also.
5 incn floppies were 128k, PC's later wrote on both sides of the 5 inch floppy making them 256k.
The 3.5 inch floppies in the hard case were 400k then Apple upped them to 800k. I think they were advanced to 1.4 meg later.
To think that we used to run a Mac on a 400k floppy that held the operating system, MacWrite and MacPaint with room left over to hold all your documents.
I think there were 8086 and 8088 chips before the 286 and 386. </C>
