There was once a persistent entrepreneur who founded a chip company which became, at the time, the fastest growing company
.
The company waxed fat as the spread of IBM clone PCs encompassed the globe.
Then the persistent entrepreneur (who was an ex-Intel guy) decided to go one step further and replicate the x86 microprocessor as well as the chip-set.
It was a step too far. The resources he spent developing the processor and fighting legal battles with Intel saw his company overtaken by others in his core, chip-set market.

Portable devices become powerful enough
to run standard applications. And now there
are user-friendly thanks to the most famous
one. Which is powered by ARM cores.
Which company was this?
