I ran the identically labeled lines for a 27C128 to the ECM.  IE: A0-A16, 
O0-O7, power, ground, OE, etc.  the lines that were additional on the 
27C010 should only be A17 thru A19, and those were switched to ground thru 
the thumbwheel switch.  I can draw up a diagram tonight and send it to you 
(and the list for that matter, as much interest as there is!)
