Just say no?????" - me I'm mailing this because we don't have outgoing posts turned on. If you are into it perhaps you could post it for me. Actually the A501 lives in $C00000. This turns out to be on the same side of the gate as the Chip memory so behaves as slow memory. However I don't think this is where the other 512K of chip that the Fatter Angus will use will live. From my hardware background I would guess that the additional chip ram will live from 080000 to 0ffffff. I haven't had a chance to stare at the gate hardware but it is on my list of things to do. -c -- cire|eric Eric B.
