Radikal Bikers by Atari/Gaelco   1997?
Not standard Jamma pinout,  Damage will occur if Jamma
harness is connected. IC#1will be damaged. 
IC#1 is a TD62064AP 16 pin DIP.
 See below

Eproms   U-24,25,26,27,32,33,34,35    are 27c010 devices

Eproms  U-6, 12, 14, 19  are 27c040 devices

This is not a complete set.  Surface mount EPROMS still need
to be read.  IC's 8, 10, 17, 15, 23, 45, 48

           Pinout differences between normal jamma:

don't connect pin 5 (component side --- normally   -5 volts)
pin 9 and K (K is opposite of 9)  9 is left speaker + and K is speaker -
pin 10 and L are normal speaker connections (right +and -)
Coin 2 isn't used.
             Player 2 - none of these pins are used

             Player 1:
Up = volume up
Down = volume down
left =  handle bars pulled back  (wheelie?)
right = not used
push 1 = View
Push 2 = Brake
Push 3 = accelerator
push 4=  Left and right potentiometer
