     There's a fellow in our local club that uses a SuperController
  II, and has a SmartWatch installed in its ROM socket.  He has a
  question concerning the drivers found in SWCLOC.AR in Lib 10.  They
  are all slot-specific which seems to mean that they assume that an
  MPI is plugged into the system.  However, since he doesn't use an MPI
  (the SCII handlesuhis HD, FD, and RS-232), he's wondering if it even
  matters which SWClock driver and GetClk program he uses in his
  system.

       The only differences that I've been able to find among the like
  modules contained in the ARchive (besides the CRCs) are the slot
  select codes.  For instance, the module SWCLOCK4 has, starting at
  1EB, an 8633 (LDA immediate) followed by a B7FF7F (STA), and SWCLOCK3
  has an 8622 followed by the POKE (STA) that actually does the slot
  select.
       Since the B7FF7F is addressing the Slot Select byte that only
  means something if an MPI is plugged in, would it be necessary to NOP
  the 86xxB7FF7F instruction sequence with 1212121212, if no MPI is
  plugged into the CoCo?
