rowe r91 help needed

[scottie]

ive just bought a r91 hideaway and wall box

bought as a non working machine for a project

the computer is giving error 9 which according to the manual is a coin switch fault, as im using a wall box(mhg/rainbow) there is nothing plugged into the computer's coin switch socket, would this mean there is a fault with the coin switch on the wall box, the display on the wallbox says error 1 but i can find no info on this type of wallbox

for my project the wallbox is not needed so what i am thinking is to get a hold of a r91 kepad/display and hopefully this will let me clear any error codes and use them instead ofthe wallbox stuff
