 Hi,

 I  have a coin jam problem. I tried to install a new bill acceptor (110v) and when I plugged in the nine pin plug and inserted the bills for a test, everything went fine until a "coin Jam error came up on the screen. Now I can't get it to register points. I power up the machine and everything is fine, put money thru the bill acceptor and can hear the pulses..but no points register and then coin jam appears. If I startup and hit the setup button I can change the bonus settings, but then when i hit it to exit, the coin jam message comes up again. When I try to put points on manually by taking pin 18 to ground it registers the points, but the dreaded coin jam appears. I tried removing the memory chips and doing that I broke off two pins, but was able to resolder them on. The board is now back to the previous state. Any ideas??   and     Does anyone know where to get a replacement memory chip? Chip says:

Winbond
W27C512-70
909GE28511710-511VE

(sticker on chip says)
VH96SE-L

One of the resistor packs on the board may have gone bad I would check them
