The problems with Apollo cards are that they stupidly did not solder the timing crystal. The crystal moves, if the computer is powered, you can fry parts of it. The card may not die altogether right away, but it will be flaky. One day you'll power up and get a black screen. BTW this happens with 68040' cards as well.
This happened to my Apollo 1240.
I did get it repaired, and had an 68060 installed, but it runs at 40 mhz, still better than any 68040 out there and cooler with no fan needed. So yeah I have the slowest 68060 card in the world..
