Marcello,

A further thought on this - can we assume that what you have in the  29C010 
is the fuel / ignition map ONLY, i.e. no executable code?  If  it contains 
both, then more complexity is needed, because you only want to  assert the altered 
higher address lines when a fuel / ignition lookup is being  performed.  But 
you could still use the simple approach Bevan & I are  advocating if you have 
four images of the executable code as well, each with  their own respective 
map but otherwise identical.

Regards

Will Cowell
