I used to have (still do, just don't use it anymore) a ][+ with a Videx Ultraterm that sounds similar in design. It had two RCA-type phono jacks (ie. monitor jack) whereas you would run the output signal from the motherboard into the interface and then the output from the interface to the monitor. This allowed for the signal to be processed before getting to the screen. The only snag in this (wild and crazy?) theory of mine, is that you stated it had two pairs (ie. four) of jacks similar to the *speaker* jack.... Anyone else wanna take a guess?

Some of the Videx-compatible have similar jacks. The cord which attatches to one set of the pins converts the two-pin output to an RCA-type jack (which goes to the CRT.) The second set of pins may be the input port for a Light Pen. (No, I don't know how it works. :-) ) -m@ (Matt Braun)
