- I picked one up a while back. It does run but the speed up is marginal. The
- best I saw was 1.9 time my regular A4000, and that was doing a procedural
- texture in Imagine. Normally it is only 10%-20% faster.
-
- Too use it I needed a better power supply. It might be worthwhile to put the
- actual cpu in a Warp engine if the Warp's clock can be pushed to 50Mhz. I
- might do this rather than get an '060, anbd the wait for a PPC.
