@ OP:
Welcome to the forums. Most of us are well versed in multi-platform systems. We all have a love for the older macs as we feel they had more personality than the machines now. So we toil on keeping the ones we have running and finding new (conquests, liberations) sources of parts and machines to fuel the madness.
RE: DX2
The DX was shipped at 33MHz. The DX2/66 is clock doubled to 66MHz. This occurs inside the chip, not the mobo. Yes I know most older 486 board had jumpers, but back in the day we also had to set the proc voltage and sometimes it varied. They (Intel) went to a clock tripled setup shortly with the DX4/75 and DX/100 machines. The DX4/100's were awesome.
When the Pentium came out, all we needed to set via jumpers was bus and multiplier ratios (voltage jumpers were still present if you had a Cyrix or AMD CPU though). This was years and years ago, I could be off on a detail or 2.
Enjoy your stay here.
