It had a terminal attached to it, and was serially controlled, since it predated all the gui crap that is around today. We have one or two stashed around here, but they are rare. I have only seen two on Ebay in several years that were worth buying. I guess people kept the parts that were labeled related to target processors, and trashed the main box for some reason. The ML 4100 analyzer would not have a socket on it, and would have a 60 pin cable that goes to the 4100's front connector. The ML 4400 has to have special analog circuits on the pods, and has several plug in cards, ranging up to some that are pretty competitive with the HP 16500s with 2m x 500mhz deep capture cards in them. The bad news is that the pods are rare, as most ML4400's were married with Pentium or Pentium Pro run controls that had custom logic for the analyzer, and no general purpose way to hook up to the devices under test.

The interface from the pod to the emulator *card* (what you call the interface card) varies based on the emulator itself (think of the pod and the emulator card as a single assembly that is split to minimize the amount of logic that needs to be out near the target system -- that the emulator pod plugs into). The interface from the emulator card to the rest of the "system" is somewhat standardized. I can dig up details of the connector signals if necessary (though you really won't be able to *do* much with that info as it is also "proprietary"). There is also often a ribbon cable on the "outside" edge of the emulator card that ties in to the high speed memory card on some emulators (IIRC).
