looking for a working sys11 cpu board
ok. it looks like an 11b that was converted to an 11. it has iJ15 installed and used. fully populated sound section. game rom at U27, nothing at U26. sound roms at U21, U22. board part # d-11883-1-1921 .
rottendog has an new 11a board. would adding connector IJ15 make it an 11 board? is it even possible on his board? ideally, i guess i'm looking for a sys 11 board, or a sys 11a board i can ad an IJ!5 to.
anyone ever work on a sys 11 bowler? am i on the right track?
thanks much
mike
