The A2040 is designed to go in the processor slot of
an A2000.
Now the Zorro 2 slots in the A2000 and on your A500 do not
carry all the nescesary signals to reqired by a processor card.
However they can be modified to do so, so I suggest you
look at the pin configurations of the slots and add the required to your Zorro slots.
