As others have stated, PC cards don't emulate the Intel processor set but they generally fo emulate the PC graphics function. For the Orange386 card, the CGA graphics emulation is the really slow bit. When I installed a VGA card in the Orange386 expansion slot, I was quite surprised by the speed -- pretty much what I remember from a real 386. For more info on the Orange386, visit http://www.mandrake.demon.co.uk/Apple/O386.html. John Ruschmeyer has documented the AST 286 card very thoroughly at http://homepage.mac.com/jruschme/Mac286.html. I have one of these cards too but haven't played much. The 286 card is a lot less hackable than the 386 and I'm waiting for some inspiration about how to use it. Using the once removed rule, it's also worth mentioning the AST 8088 card for the SE (never seen one of these), the Dayna MacCharlie for the 128 and 512 compacts and Apple's own 486 cards for the Quadra 610 and others.
