Apple PowerBook 145b The Apple Macintosh PowerBook 145b features a 25 MHz 68030 processor, 4 MB of RAM, either a 40 MB or 80 MB hard drive, and an internal 1.44 MB floppy drive in a compact portable case with a 9.8" monochrome passive-matrix display.

The PowerBook 145b is quite similar to the PowerBook 145 it replaced, but the 145b was "re-designed" to lower production costs and had 4 MB of onboard RAM rather than 2 MB.
