hello,
i have opened an old A500 and found this pcb near the expansion trap.
the amiga is on 1.3 rom and boot normaly ( i think)
it used to have a multirom sytem on it (2.0 and 1.3).
thanks for your answers.

I've seen this before on a pic in Amiga hardware possibly ? I'm not sure but I don't know what it is. Is it a commodore / factory mod ?

If you can look for some marking on the trapdoor memory card
that looks like some kind of memory fix addon for the card
since it's connected to the gary IC..
