I can only guess. It may be that this facilitates some interleaved addressing mode. I once saw where Apple swapped pins so their EROMs would not be interchangeable with the standard product.

Well, this is a very dumb question. Sorry for that.
I'm creating a circuit using the 27C160 EPROM memory in BYTE mode. The pin Q15/A-1 has the function A-1 in the BYTE mode. I'm so sorry, but it means that the memory is adressed A-1, A0, A1, A2 instead of A0, A1, A2...A-1????
Thanks Alexandre Souza
