PowerBook 145B
Laptops1993Uncommon
The PowerBook 145 and 145B were modest refinements of the 140 — a slightly faster clock, a cleaner LCD. Intended to maintain the PowerBook line's price/performance position while Apple developed the 500 series. Solid road warriors for anyone who needed full Mac software in a laptop package without paying for the premium active-matrix display of the 170.
