Space Commander compatibility

[Jon A.]

I'm squirreling away ultrasonic remotes like a squirrel squirrels away nuts... haha. Anyway, I'm just wondering which Zenith sets will work with my Space Command remote. Rather spartan design, but my favorite nonetheless. I know that not all features of this remote would work with sets it might be compatible with. I have seen other variants of this remote, one with a single volume button, others lacking the zoom button.
