Significance of this Accomplishment
 
  Significance
• This chip enabled "Motorola's" first high volume computer.

• This was Bill's first project at Motorola.

• Motorola supplied nearly 100% of the silicon components in the Coco:  Highly profitable, volume sales.  

• The MC6847 directly inspired the MC6845 design (used by nearly all IBM PCs).


Skills Transferable to Your Projects:
 
  Juggler		 Leadership / Management
