- Probably the best Amiga MBus solution would include room for a significant
- amount of memory on the MBus side of the conversion. The only real reason
- for doing an MBus board at all is to eliminate the engineering cycles necessary
- to take advantage of new SPARC processors.

- I'm a software type who has been out of touch with the hardware details
- for too long. I checked with one of the hardware types, and he confirmed
- that it would be a royal b*tch to interface the Tsunami/microSPARC to the
- MBus; so there wouldn't really be a low-end MBus solution. I still think
- the microSPARC would make a great co-processor in the Amiga. And a directly
- interfaced microSPARC should be highly compatible with an MBus-based high-end
- SPARC.
