So what keyboard/how many keyboard encoders would i need for that CP setup? Will 2 x GP-Wiz49 cover all the inputs, or will i need a I-PAC4 aswell? Also do i need a Opti-PAC for the spinner, as the trackball is a Happ USB/PS2 one, so i wont need a Optic-PAc for that, is there a spinner that uses USB/PS2, cos then i wouldnt need a Opti-PAC at all unless i need one for the 49ways with floyds conversions?
