Stephh notes for 8085 code:
0xe01d : game slot number (range 0-3) - sometimes inc'ed/dec'ed/zeroed, but also filled based on games slot status (code at 0x01e8) :
0x8009 and 0x800a : main timer (BCD, LSB first)
0xe054 to 0xe057 : display timer (main, LSdigit first, stored in 4 lower bits)
0xe058 to 0xe05b : display timer (game slot 1, LSdigit first, stored in 4 upper bits)
0xe05c to 0xe05f : display timer (game slot 2, LSdigit first, stored in 4 lower bits)
0xe060 to 0xe063 : display timer (game slot 3, LSdigit first, stored in 4 upper bits)
0xe064 to 0xe067 : display timer (game slot 4, LSdigit first, stored in 4 lower bits)
display timer (main) "filled" with code at 0x054e
display timer (game slot n) "filled" with code at 0x04e3
coin insertion routine at 0x0273
coin 1 triggers code at 0x02d7
coin 2 triggers code at 0x028f
in each coin insertion routine, you need to insert n coins (based on DSW settings) then you are awarded u units of time (also based on DSW settings)
I can't tell ATM if units are seconds (even if values in tables seem very related to them)
