OK, its the correct CPU so thats a good start.

According to Clay's old guide - Part number D-11883-xxx (where xxx is the game number) & 573 is the correct game number.

Its the photo which shows the area around header pin 1J15 that concerns me.  Looks like its been robbed it that area, but looking at the manual thats normal.

I wish I still had my Police Force, miss that game heaps.

My restoration / repair days are long gone unfortunately !
