Macintosh PowerBook 150

Introduced: July 1994
Terminated: October 1995


The Motorola 68030 processor running at 33Mhz powered the Macintosh PowerBook 150.  It came with a hard drive of either 120 or 250MB and had a 1.44MB floppy drive.  The 4MB of RAM was expandable to 40MB.  It had a 9.5” grayscale passive matrix LCD with a resolution of 640 x 480.  There was an expansion slot for a 2400-baud modem card.  The 150 had serial and SCSI.


At $1,300, the PowerBook 150 was the first PowerBook that was priced for the general user.  Lacking an ADB port was a limitation as was the lack of Ethernet or monitor jacks.  But for the price, it was lightweight and fast.

  • It has been such a long time when I saw devices like this work. Just look at the Window of this notebook. I am just wondering if there is a rich history of processor manufacture in Motorola. - Guy Riordan
