My MicroA1-c just locks up on occasion. It's either the core voltage or the fan-cooler. I'm probably going to replace the PPC 750FX with something G4-level after the announced CPU-modules come out in June. Then I should be able either to use it or sell it and buy a PowerVixxen LT for my A1200.
I bought it when it looked like the Micros had the bugs fixed that the XEs had. It seems that I was wrong about the Micros but I'm still happy with the AmigaOS 4.0 prereleases.
