What is it?

This is a pre-assembled board meant to be used as a replacement for faulty '503' custom ICs used on some Konami arcade PCBs from 80s like:

Pooyan
Track & Field/hyper Olympic
Shao-Lin's Road/Kicker
Pandora's Palace
Roc'n Rope
Time Pilot
Time Pilot '84
Yie Ar Kung-Fu
Gyruss

Why did you make it?

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

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.
