PowerBook 145b

Compared with the PowerBook 145, this model has all 4 MB of memory on the logic board, which leaves the memory slot free for expansion. Apple cut the price to US$1,649 and shipped a single backup floppy instead of a full set of system disks. The 25 MHz 68030, the 9.8-inch black-and-white screen, the case and the 40 MB hard disk did not change.
