Here is the goods from an Apple Document:

  To convert a IIe to an enhanced model, it must have an old revision B logic 
board or newer.  If it has an old revision A board and it is not stamped "VAR", 
it is elegible for the free Rev.A to new rev.logic board swap under repair 
extension code OAA324.  The enhancement kit consists of a new CD ROM 342-0304, 
EF ROM 342-0303, 65C02 cpu (338-6503), and Video ROM (either 342-0265 for 
English or 342-0306 for French).  If double hi-res graphics are to be used, the 
jumper on the extended 80 column card must be connected. (However the new 
mini-extended 80 column cards don't have this jumper).


  I recently bought about 20 IIe enhancement kits and sold most of them to a 
gentleman in california, Charlies Appleseeds as I remember, if your interested 
I can look up the info and you can order one from him (it has everything, 
shrinkwrapped even!).
