The jumper setting might be the same as a couple of mine. I will take a look when I get time and let you know.

If you want to add more ram consider 2 new developments. The Kipper 2k 8MB and the ACA500.

The Kipper2K adds 8MB of ram to the A500 and piggy backs over a chip in the motherboard. I've got the A600 version and it works perfectly.

The ACA500 is something quite interesting. It plugs into the side expansion slot and adds 2MB fast ram, but also provided a 14MHz 68000 and CF slot that works as an internal HDD. Giving the same ability as using one on an a1200. Quite cool.
