Apple Macintosh PowerBook 150 build in 1995
The Apple Macintosh PowerBook 150, using a variant of the PowerBook Duo 230 motherboard, features a 33 MHz 68030 processor, 4 MB of RAM, and a 120 MB hard drive in a compact portable case with a 9.5" grayscale passive-matrix display.
The PowerBook 150 replaced the 25 MHz PB 145b. It offered the faster performance at a lower price and was the final model in the 140-145-145b-150 line of economical PowerBooks. Finally, the 150 sported a 640 x 480 display, the same size as a regular monitor. Using the same memory modules as the Duos, the PB 150 was far more expandable (to 40 MB!) than other PowerBooks in the 100-180 series. The PB 150 was also the first PowerBook to use an IDE hard drive.
