Following on from Reverse engineering the coin box, the microcontroller used is the MC68HC908JL3 DIL-28, or a similar derivative.

Documentation

MC608 28 pin, at Mouser

 

In particular, I need to obtain a dump of the embedded code contained within one of the pre-programmed µC from the coin controller PCB and be able to program other microcontrollers with that image. See How to read flash from Motorola/NXP mcu which provides these links:
