Interesting.  (Netters: I wrote Davex, by the way.)  Does any other software
have trouble with your card installed?  Do I understand correctly that the
card replaces the F800-FFFF ROM range when the switch is in one position,
and has no effect in the other position?

Are you using a II+?  IIe?  What ROM routines have you modified?

What sort of a "screeching halt" does Davex come to, and when?  (Does it
hang, crash [where?], etc., and what is on the screen at the time?)
