: I'll have two PS/2 trackballs, both connected to a PI Electronics PS/2 port splitter, which then runs to my computer's PS/2 port. From there I plan to use AdvanceMame to seperate and use the two trackball's signals for two-player games (marble madness, etc etc)...
That won't work, the trackballs have to be connected to different places, a "splitter" only switches between the two to make the computer think that they're one trackball.
: I'm also going to have a Hagstrom K72 encoder. Is there a good reason I should get the K72T and run the trackballs to that before they go to the computer? Is there any difference?
If they're arcade trackballs they have to each be connected to an interface. If they're PC trackballs you don't need an interface.
