  Ok, here is the definitive answer on CPU replacements for the Atari
8-bit series....
  
  400/800 - CPU can be switched with a 65C02, and 65802.  Nothing else is
needed.

 1200xl, 1450xl, 600xl, 800xl, 130xe, XEGS - all require a special board
to perform some multitasking stuff in order to replace the CPU.  The
only board (that I know of) that does this is the DataQue 65816 CPU
upgrade.

  The particular design (NMOS/CMOS) used in the chip makes no difference
(except perhaps in power consumption, and that is negligible).
