Hi.
The adapter.. What kind of RAM does it take ?
Does it look anything like this that i submitted to Big book ?
http://www.amiga-hardware.com/showhardware.cgi?HARDID=1697
MY expansion, the Gary adapter connects to the trapdoor expansion via a 3 wire cable.
It did not employ a cable to the Agnus, it employed a single cable from a solder point (JP9) over near the CPU that connected to the Gary adapter.

Yeah sorry, I did mean JP2.
I only went with the instructions in the manual, to use THAT jumper block as the source to wire to the Gary adapter.
JP2
