In comp.sys.apple, Rankins@DOCKMASTER.ARPA asks about enhancing a IIe:
          >1. How can I tell for sure if my //e is enhanced or not?

              You can tell through software. Location $FBC0 holds
              $EA if original ROMS, $E0 for enhanced ROMS, and $00
              for a IIc.

          >2. ...  Is this something I could do myself or...
          >   ...how much approximately would they cost?...

             I did it. It helps if you know how to handle chips. Also,
             I actually found enhancement kits at the Crescent dept.
             store in Spokane for $5.00 (!). I bought two of them and
             gave them to friends. I installed one for one friend but
             the other one did it on his own, bent a bunch of pins
             and blew a drive chip somehow. He destroyed his enhancement
             and spent $40 bucks for repairs. Caveat Emptor. If you
             do it yourself, it actually is very simple. Just be very
             patient with removing the old chips, slowly prying them
             up with a small screwdriver, being careful only to pry up
             the chips and not the sockets, then very carefully inserting
             the new chips by putting in one side, then applying slight
             sideways pressure until the next side of pins are lined up
             enough to apply downward pressure to seat the chip in the
             socket.
