    The result of this was a 'dead' amiga, so the original 1.3 chip was replaced
    & all was well again.

    Hello,

    You have to connect pin 1 and pin 31 at the socket (not the ROM!). Then you must leave pin 31 out of the socket and connect pin 31 and pin 21 on the
    ROM. This works fine at my A 500 Rev. 5 with Kickstart 3.1 (40.63).
