The PowerBook 150 was introduced in July 1994 and discontinued by October 1995. It was designed to be a mid-level laptop like the PowerBook 140/145 models.

General Information

The PowerBook 150 computer retains the physical appearance of the PowerBook 145B computer except that it houses a logic board built upon the PowerBook 200 series system architecture. This new logic board not only increases the processing performance of the PowerBook 150, but also allows for greater flexibility of RAM expansion. In addition to the increased performance and new RAM expansion capabilities, the PowerBook 150 also incorporates an internal IDE drive, rather than an internal SCSI drive.

CPU

The PowerBook 150 uses a Motorola 68030 clocked at 33MHz. There is no math co-processor in this model.

Memory

The PowerBook 150 includes 4MB RAM onboard, expandable to 36MB (single memory slot). The RAM expansion slot accommodates Macintosh Duo system RAM expansion cards up to a total of 40 MB of RAM.

Video

Liquid crystal display: film super twist nematic (FSTN) 2-bit-per-pixel (4-level) grayscale, 640-by-480 pixels, with adjustable backlighting.

The PowerBook 150 video display is a 9.5-inch flat panel film super twist nematic (FSTN) dual-scan liquid crystal display (LCD). It provides 640-by-480 2-bit per pixel resolution, is capable of displaying 4 levels of gray, and has on-demand cold cathode fluorescent lamp (CCFL) backlighting. The video implementation on the PowerBook 150 is similar to the video on the PowerBook Duo 230. The video RAM is a 128K x 8-bit device that stores the data required to update and refresh the flat-panel video display.
