PowerBook 140
Laptops1991Uncommon
The PowerBook 140 was the mid-range of Apple's original 1991 PowerBook lineup — a 16 MHz 68030 with a passive-matrix display, positioned between the Sony-designed 100 and the premium 170 with its active-matrix screen. It established the PowerBook form factor that competitors scrambled to copy: trackball centered below the keyboard, wide palm rest, portrait-oriented display.
