Looking for some guidance on controlling cheap Radio Shack rotator

Bought a $55 special TV rotator from my local Radio Shack, and I would like to use something to control Azimuth (Elevation is obviously fixed, I have it at 30 degrees which seems OK for my use). It has three screw posts (probably +/- DC voltage and ground for motor control?)
I have an older PC with a parallel port (serial port is used to control the rig). What pre-existing interfaces between parallel port and the screw posts of the rotator are available? I don't have the time to build my own kit, and would rather buy off-the-shelf solution.
Thanks.
