- The r4k indigo has cpu, cache, and clock on a seperate board for
- similar reasons, in hopes of being able to go to 67 or 75 Mhz
- (maybe 100?) someday without changing anything but the processor
- module. Of course, I couldn't say when or if we will announce
- such an upgrade.

- Such hopes don't always work out, as can be seen by studying
- older systems that tried to use this scheme.
