The PowerBook 150, introduced by Apple in July 1994, was the final model in the 100-series and the most affordable PowerBook at the time, featuring a 33 MHz Motorola 68030 CPU, 4 MB RAM (expandable to 40 MB), and a 9.5" passive-matrix grayscale display with a resolution of 640×480. It was notable for being the first PowerBook to use IDE hard drives instead of SCSI, but it lacked an ADB port and external monitor support, reflecting its budget-focused design.
