Guess what I found? Luke Dormehl and the original Mac PowerBook 100. My first Mac notebook, circa mid-1992.
The October 1991 PowerBooks came in three configurations: the low-end PowerBook 100, the midlevel PowerBook 140 and the high-end PowerBook 170. These ranged in price from $2,300 up to $4,599.
I bought mine in late summer 1992 for $999 from Businessland. 40MB hard disk drive. Black and white display.
