PowerBook 145

Compared with the PowerBook 140, this model has a faster 25 MHz 68030 in the same case, which made it about 35% faster. It came with 4 MB of memory and a 40 MB hard disk, and it still has no FPU. It sleeps or shuts down when the display closes. It replaced the 140 and took the PowerBook 100's place as Apple's entry-level notebook.
