Reelf,

Out of interest, which parameter(s) of the '84A that differed from =
those of
the '84 were you caught out by? I am well aware of the differences
documented on the Microchip '84 -> '84A Migration note (which I have in
front of me now), however I'm just curious about what particular =
problems
you encountered. Did you find that some programmers designed to work =
with
the '84 didn't operate correctly with the '84A, maybe?

Appologies in advance if this has been discussed before. No doubt it =
has :o)

Cheers,

Trevor.
