What is it?

This is a pre-assembled board meant to be used as a replacement for faulty 'CUS98' custom ICs used on Namco arcade PCBs like :

• Pre-System86 hardware (Gaplus, Pac-Land, Sky Kid, Dragon Buster, Toy Pop, Metro Cross)

• System86 hardware (Rolling Thunder, Ski Kid Deluxe, Hopping Mappy)

Why did you make it?

I did it because the original part breaks very easily, making expensive and valuable arcade PCBs useless.

What makes it special?

The replacement has exactly the same functionality of the original part which is known to be prone to failure.It's the only replacement available so far, nobody else made it..
