1943 CAPCOM Board Battle of Midway 8751 security ic 7K
Hi
does anyone have a eprom dump for the 8751 ic 7K?
I have a bootleg 1943 with no sound. It has a 8748 on a sub board along with a 7404 to invert things like the reset line to work with the 8748 in place of the 8751. GREAT I thought the 8748 does not have protection on it! but when trying to read it in the dataman 48LV it just shows the EA pin faulty and therefore can't read the eprom! and I am sure is why there is no sound! (if EA pin is not grounded properly inside then it won't read the eprom section)
so back to square one! needing a dump of the 8751, can anyone help with the code dump???
many thanks
Andrew
