Neither the 200-4R nor the 700R4 (yes, the "R" is in a different place) are computer controlled. The only computer function on either is the torque converter lockup, which you can control with a toggle switch. Both use a TV cable because they were designed to operate behind turbo and/or diesel motors that don't have a consistent manifold vacuum signal. The TV cable simply combines the functions of the vac modulator and the kickdown cable. It is essentially a mechanical throttle position sensor.
