• This was "Motorola's" first high volume computer. • Motorola supplied nearly 100% of the silicon components: Highly profitable, volume sales. • The novel design used a unique MC6809E CPU (which very nearly became the CPU in the IBM PC). |
 |
Leadership / Management • Bill led the entire computer project (Motorola's role). Theory / R&D • Bill's experience designing DRAM controllers (MC6883) and video display chips (MC6847) enabled this computer. • This includes Bill’s numerous insights in hardware design (CMOS design, pipelining, memory architectures, video standards, NTSC, PAL, SECAM, ALUs and microcode). • Bill proposed and prototyped innovative graphical input devices, too. Software • Bill directed software development for testing and for demonstrating the computer. • Bill architected special test software and supporting hardware for the initial chip "bring up" for the MC6883 which served as a system-integration chip for the computer. Hardware • Bill designed all of the logic in the MC6883 and MC6847, and their integration with the CPU (all, except the mass storage interface). |

By pushing beyond the current state-of-the-art, there are these opportunities: • Although Windows PCs have dominated for years, their high power consumption and high silicon complexity have severely slowed the progress of battery-efficient, low-cost, portable applications. • As this computer design demonstrated, fresh re-thinking of the system, as a whole, can make enormous simplifications, thereby driving down battery-drain and costs (e.g. See the Negroponte $100 laptop per child project). |
