PowerBook 145

The PowerBook 145 replaced the 16 MHz PB 140, using a 25 MHz 68030 CPU that made it significantly faster than the previous model.

PowerBook 145As with all early PowerBooks, when buying one be sure it has all the memory you need (new PowerBook RAM is getting difficult to locate, especially at reasonable prices).

The PB 145 has an 8 MB memory ceiling, although you can go beyond that by using Virtual Memory (slow and free) or RAM Doubler (faster, not free, and discontinued). Another option is RAM Charger 8.1, which offers better memory management than the Mac OS.
