- Yeah. I guess I'm the liar.
- Acorn's 32000 transistor cpu does not include cache. It's also only
- a part of a cpu. The Acorn team will put this cpu on a chip along with various
- goodies and extras. This can include cache, mmu etc. The cpu part takes up
- about a quarter of a 22 mm die.

- But still, being fast and cheap, why aren't they used in more places?
