Jim,
Actually I'm just guessing that these are emulator boards. I'm not
positive what they are.
I have several of these but ot the machine that they go into, just the
pods and interface boards. The pods that are attached to interface boards
with two ribbon cables. There's also a short ribbon cable that connects to
the pod and to a DIP plug that looks like it's supposed to replace a CPU.
The pods are in metal box about 10 x 7 inches square and slightly over an
inch thick. The bottom over on the pod is hinged and you can open it up and
see the emulator card. This card is marked 6800/02/08. The interface card
is about 6 x 10 inches square and has female connectors that are made to
fit over small male pins. I don't know the name of these connectors but it
looks like the same connectors that used on the SS-50 computer cards. I'll
try to get some pictures tomorrow.
The box is the emulator pod. 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).
