PowerBook Buyer's Guide

PowerBook 140/145/145B

The 140, 145, and 145B were the first PowerBooks to include an internal floppy drive. They have 10" black & white screens which are suitable for viewing text or spreadsheets, but are not really designed for viewing graphics. The 68030 processors running at either 16 or 25 MHz are faster than the processor in the 100 and fine for basic applications. These PowerBooks were the first mass-distributed 'Books and were likely to be found in your local Circuit City or other computer store back in the early 1990's. Of the three, the 145B is the best buy with its larger hard drive and more memory.
