The detachable keyboard contains indicator lights on both CAPS lock and NUM lock, whereas the rest of the keyboard mimics IBM's design. The AT&T PC 6300 contains another key set of features that combines the IBM PC and IBM PC-AT together. Note that the 16-bit expansion bus accepts boards proprietary to the IBM PC-AT design. The bottom cover opens revealing an 8MHz 8086 processor, a battery-backed clock and calender, up to 640K worth RAM banks, an opening for the optional 8087 NPU, and so much more, all in a case a little longer front-to-back than the IBM, but quite a bit smaller side-to-side. The 2-piece case opens on top to reveal the 7 slot expansion daughterboard, including 2-3 16-bit ISA slots, built-in video card, 110V PSU, and disk drives. AT&T built a solid IBM-PC compatible based on what worked in the past, what workes now, and what the future needed. The AT&T PC 6300 was AT&T's first attempt at making an IBM PC compatible, and it did a fabulous job with it. AT&T had taken its size, household name, budget, and reputation for quality into the computer marketplace with the 6300, an imported Olivetti-made IBM PC compatible. For better or worse, the breakup of Ma Bell had forced giant AT&T to crawl out from under the monopolistic blanket of protection and into the competitive high-technology arena.
