: The only interesting tidbit in there is the (TTL or MCOcS COMPATIBLE) phase. Anyone know what this means?
If the ouptuts are TTL compatible, a logic 1 must be at least 2.7 volts and a logic 0 no more than 0.5 volts (at least that is what I remember from way back, I'd need to look it up to be sure). If the other acronym is synonymous with HCMOS, then I think that the logic 1 level would be a bit higher. My guess is that it will put out something close to 0v for a logic 0 and close to 5 volts for a logic 1. It also sounds like they are putting out quadrature outputs for x and y. This probably means that it is not a serial or PS2 interface, and one would need to have something equivalent to mouse circuitry to decode the quadrature signal into either a serial or PS2 interface. You could probably use one of Happ controls interfaces, or tear apart a mouse and find the points where the quadrature signals are generated and wire in these signals. The thing might also be a power hog, so you may not be able to power it from the serial or PS2 ports either.
Of course, all of that is based on a babelfish translation, so take it with a grain of salt.
