PowerBook Duo 280c
Laptops1994Uncommon
The Duo 280c updated the 270c with a faster 33 MHz 68LC040, the first 68040-based Duo. Still in the same ultra-thin chassis introduced in 1992, the 280c represented the pinnacle of the 68k Duo line before the PowerPC transition. Its successor, the 2300c, would bring a PowerPC G3 to the same concept.
