What is it?

This is a pre-assembled board meant to be used as a replacement for faulty 'RCDM-I4/RCDM-I5' custom ICs used on some DECO/Data East arcade PCBs like:

  • Karate Champ
  • Karnov
  • Last Mission
  • Express Raider
  • Bogey Manor
  • Psycho-Nics Oscar
  • Boomer Rang'r
  • B-Wing
  • Break Thru
  • Breywood
  • Darwin 4078
  • Fire Trap
  • Shoot Out

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.
