Comments
The Macintosh II represented a break from the all-in-one original Macintosh. It was Apple's first attempt to put the Macintosh platform head-on with the expandable IBM compatibles. The Macintosh II was a completely different computer than the previous Macs. It was expandable, complicated, loosely configured, and very powerful. The previous Macs were tightly configured all-in-ones with closed-systems, which sacrificed performance for economy. The Macintosh II, on the other hand, was three times as expensive as the all-in-one Macs. It was a box-monitor (modular) system with a removable top and expansion slots like the Apple II. The Macintosh II had six powerful NuBus expansion slots available to expand its basic features.
