  Sure does. Basicly when you set the jumper (or use mouse buttons) to boot
  in 68000 mode - the 020 board is non-existant (so to speak). The memory is
  gone as is the extra speed, MMU, co-processor..... you get the idea.

  How true. But I can cay that over the past 2 years the number of incorrect
  programs compared to correct ones has gone way down. (I dont use alot of
  games so I leave them out of my comments). Currently I am able to use all
  the programs I want/need in the 020 mode. (IE: compilers, lint, spell checker,
  Dos-2-Dos, ect, ect)

  Think I just did ;-) But if I do find a prog that will not run w/the 020
  (so far only games & _early_ releases of some software), I just boot as a
  68000 machine and all is well again.

  U R Welcome.
