Hi, answering for Kipper2k :

You'll need to install the new pins .

and Possibly the 8572a for the 1mb chip, Expansion ram to chip (not fast memory)

But not 100% sure on the address line hookup etc.

; vague I know but this needs testing. Maybe someone else here will know more.

Do you have an a500+ to test , would be easier than modifying your rev5

Kipper2k added:
"8572a, 512k expansion and some jumpers cut/reset"


Here is a good reference regarding upgrading a500 :
