- This is an overdriven chip. Motorola only guarantees it operates at
- a frequency of 33MHz. You can push them at higher frequencies iff a) the
- particular chip you have can take it (not all chips can be pushed) b) you use
- one mother big heat sink to deal with the extra power that needs to be
- dissapated. The problem with overdriving your chip is that it may work when
- you first get it, and it may work during a "burn-in" test to see if the chip
- works, but because of the extra heat you can have damage creep into the chip
- until it is eventually unusable.
-
- However, it is NOT like the DX2 chips by INTEL (as one of the other
- posters had mentioned). The DX2 are rated to go at the doubled speed, and
- yes they have an external speed of half the internal speed, but if you have
- a decent internal cache, you still see signifcant speed increases (much larger
- than the early ST accelerators that only accellerated the CPU without
- accelerating the memory it accesses).

- Sounds like it would be neat to see in action. Does it come with
- more connectors? Like VME, SCSI-2, PDS, others?
