Replacement battery holder for the CPU board

The Data East holder is soldered at two points, but the board is drilled for a six-point holder, so the sturdier Williams holder A-15814 (as used on WPC-S and later) fits after clearing the four extra holes.

Systems

• Data East CPU Version 1/2
• Data East CPU Version 3
• Data East/Sega CPU Version 3b
