I got the US Digital PC interface card. It has 4 channels, so, while I'm
only using 2, one for X and one for Y, I can expand to a Z axis if
necessary. At this point I don't know what I'd do with a 4th dimension,
speed I suppose.
A common usage for the fourth channel would be for a rotary table, or
something along that nature,
