When was the first laptop computer introduced?

Kiwozzie, The media surface was a disc. 5.25 inch were floppy.

Kiwozzie, You're thinking of the 3 inch disc. There were also 5.25 inch discs where the covers were like cardboard.

I had no idea it was so early that the laptop was introduced! Thank goodness for the 60% hint!

Never heard of either of these machines. I started using an Apple Classic in 1985.

Ah the floppy disc - not a disc and not floppy. When computers had A: drives.
