I had a think and thought about firstly updating the FPU chip from the stock 33MHz to a 40MHz one from Exxos' store. I know that the original one can be over clocked but I just want to put the least stress on my precious TT. I also wanted to make it as intrusive as possible and went about trying out the 40MHz and 48MHz to test and plumped with the 48MHz as the system handled it under stress testing.
To make this intrusive I just wanted to be able to plug this in without any soldering to the board. Initially I created this simple XTAL, DIL and leads setup.
Below shows the individual components and the one with leads is the 48MHz crystal in the dil socket wired and wrapped in insulating tape.

What makes this a plug and play solution is the circuit can be plugged into the +5v and GND pins on the top of the Storm memory card and then the output lead to the middle pin on the FPU clock selection jumper.

I will post benchmarks of stock and overclocked FPU shortly.
