A question for the tech guys.

If there was a series of momentary contact buttons available, say six or so, how would you get the Empeg to pay attention to them? Both hardware and software wise that is.

Can the display board be hacked to accept more inputs? Use the serial port with some kind of simple circuit? Something else unexpected?

The uses could be many, radio presets, clock on demand, info on demand.

What would you do with a few more buttons?

If you wired them to a resistor network, you could plug it into the tuner module and it would work like the steering wheel control interface. At that point, a kernel hack could remap the values to any IR commands the player would normally interpret.

If you wired them up to a custom PIC like in John Lambon's system, then you could program the PIC to send whatever ASCII codes you wanted to the player's serial port. You could either use existing serial port commands or come up with some kind of hack to re-interpret those commands.
