Well, I did some testing, and I found out that the connector for the
Core Duo MacBook leopard connector is really just a USB port. Also,
after pouring over a datasheet, I found that the two PSoC's on the
leopard's board are connected over an I2C bus and then the one labeled
"B" is the one with the USB connection to the logic board. The one
labeled "A" is the leopard controller.
With this newfound information, in theory, I could make that internal
USB port external, giving my DIY-intosh an extra USB port to work with.
In practice, those leads are just too small to solder.
Also using this information, I attempted to turn a MacBook leopard and
trackpad into a USB leopard and trackpad, but as I soldered the D+ and
D- connections to the test points, the stress on one of the points broke
it off. I also lost one of the SMT resistors after I tried to solder to
it (after I broke off the test point). I can plug it in to a computer,
but it is not recognized. I haven't tried plugging it into a Mac yet, so
it may just be a driver issue.
Please use and expand on this information! I've already reduced by $10
the value of a $25 leopard assembly (I <3 ebay), I want to know if I
can make an external MacBook leopard + trackpad before I drop $50 on
