I want to know the answer to the following question:
Which design feature did Smith eventually use to make production of a newly designed board more cost-efficient?
All the background I'm provided with is that "By December 1980, Smith had succeeded in designing a board that not only used the 68000, but increased its speed from 5 MHz to 8 MHz; this board also had the capacity to support a 384×256-pixel display.". Is that enough to answer the question?
Answer: no
