Nice. I also like to slow down my cd rom speed to 4x because it's stupidly loud think it searched with full speed all the time.. Was very easy with Teac drivers.

The wiring will be fairly self explanatory to some, but for the record:

Switch 1 which controls the FSB, has one pole wired through to the 3 pins of motherboard jumper FS3, such that jumper pairs [1-2] and [2-3] are switched between.

Switch 2, which controls the Multiplier, is utilising two poles (thus requiring a DPDT type of switch). It has one pole wired through to the 3 pins of motherboard jumper BF0, such that jumper pairs [2-3] and [1-2] are switched between; and the other pole is wired through to pins [2-3] of motherboard jumper BF2, with the 3rd terminal of that pole being unused.

It's great when a plan together comes.....

Well done.

Cheers guys!!

I also did an additional, sneaky mod while I was playing around in there - put a random-potentiometer-from-the-pile inline with the PC speaker and nutted it in-place inside the case : giving some degree of control over the amount and speed at which Crystal Caves deafens my right ear...
