    • Namco '6xA1' reproduction

      Here's my last reproduction of a custom IC, or better, this is a 3-in-1 replacement of the Namco MCUs marked '60A1', '63A1' and '64A1'.












      They are mostly the same part with identical package (DIP40) and pinout but they are not interchangeable.


      • '60A1' found on Pac-Land, Dragon Buster, Sky Kid (all revisions except early one), Sky Kid Deluxe, Alien Sector, Baraduke, Metrocross, Rolling Thunder and all other System86 games.


      • '63A1' found on first revision of Sky Kid.


      • '64A1' found on all System 1 games (Splatterhouse, Galaga88, Pac-Mania, etc)


      Needless to say the original part is very prone to failure (especially the '64A1')


      My replacement covers all three MCUs, you can simply select the desidered one via a dipswitch:







      Here's testing of the replacement on different boards :



      '60A1' on Rolling Thunder :






      '63A1' on Sky Kid (first revision)






      '64A1' on Splatterhouse :





      A special thank to my friend 'uchopon' for helping me to achieve this result.
