On the A500, A2000, A3000 and CDTV the IndivisionECS goes where the Denise chip sits. Obviously AmigaKit have some leftover pin/formfactor-compatible paula adapters for some other hardware that they are selling for use with the IndivisionECS in A1000. As long as the adapter is pin for pin transferred over there should be no problem in using it and just ignore the "Paula" socket on the adapter. The adapter is just to move the IndivisionECS out of the way of the A1000 PSU.
