Security PAL U35 decoding
|

JCM Bill acceptor communication (probably ID-003 protocol)
|

U35 PAL16R8 SECURITY
|
||||
PAL is connect on the BUS D15..D8
|
||||
Write Clock 8 bits in D15..D8
|
||||
Read OE 8 bit on D15..D8
|
||||
|
||||
U50 4Bit D Flop Register is connect on D3..D0
|
||||
this one seem to have 2 use.
|
||||
1. keep track of the PAL16R8 state
|
||||
2. DOOR SWITCH is connect on U50 Clear pin (D3..D0 LOW = Door Open)
|
||||
Write Clock 4 bits in D-Flop Register
|
||||
Read OE 4 bits on D3..D0
|
||||
|
||||
|
||||
Boot Section is locate in NVRAM. Interrupts Pointers are changed on the fly.
|
||||
seem to check hardware WDT ,Power Failure , interrupt system,etc.. before game start.
|
||||
|
||||
INT7 seem to control POWER FAILURE ,WDT.
|
||||
INT7 initialisation is needed to boot the game.
