Ah. Mea culpe. I thought, based on the dates that it would have been there when you posted your original message.
Well it tells you that there was a daughter card. That gives you the general idea of how it was done. True, it doesn't tell you the specifics, such as that monitor spanning was available and all of the peripherals of each could be used. On the other hand, I'm basing all this on the Outbound literature and have never gotten my hands on one (the docking card) darn it. I've often wondered if all four serial ports are available. Also, it seems like performance of anything at the Macintosh end would suffer, since that cable is maybe 8 bits parallel at most and operating at serial port compatible speeds (some peripherals use an 85C30 to interface to it).
What level of detail did you want regarding the connection of the daughter card to the host? Schematics would be nice.
