@McTrinsic:
I'm not familiar if Derringer uses a socketed or soldered to the motherboard 68030 CPU, however in order to reach 50Mhz, besides getting the above-mentioned oscilator, you will also need a 68030 CPU capable of running at that speed. AFAIK, you need at least a 40Mhz 68030 in order to clock @ 50Mhz without fear of creating damage.
If your 68030 is socketed, this job will be quite easy! If not... :-( percise soldering is required.
