Well you have quite a basket case there. The only thing you need is the a6 slot which is the antenna board. Granted you need to go into the menus and turn off what ever was in the old slots. By the way when you get to the menu it will at least give you a clue as to what the board was. If you get a down converter then the system would actually come up without the options. It will have the rollover issue so you have to figure out the gps week minus 1024 etc. But you are a long long way from that concern. Can't comment on the replaced parts. I am however sure it will bight me one day. Far sooner then later. Good luck Paul WB8TSL
