I have heard that later Powerbooks, into the early G4 series even, used ADB internally for the trackpad. What would be involved in hooking into that, I have no idea.

all I'd probably have to do is hack the connector a/o cable connection to the TrackPad.

The complicating factor may be whether the ADB chipset is on the logic board, or the trackpad assembly.

It makes very little sense for them to do have done so. They had more design experience w/ADB design than with USB, its OpenStandard offspring and the driver hooks for ADB were already embedded in the system code as noted above by comrade register. Such a case would unnecessarily complicate the TorquemadaPad's PCB and interfacing with the mobo.

The reverse was the case of locating the T-Rex sub-system on the PCMCIA expansion chassis of the 1400. The inter-board connection was a standard subset of the preexisting slow '030 I/O subsystems of the mobo. its implementation on the REQUIRED daughtercard for the PC Card mechanism saved beaucoup real-estate on said mobo.

That being the case: think of the PC Card Cage of the 1400 as . . .
