The Megadrive Expansion Port was largely detailed based on tracing the circuits in a MD1 and a Teradrive.  Since there are schematics on the wiki I added info from them to the expansion port pinout.

Still some details I'd like to know, about some of the signals, but I don't think it's terribly important.
