Price:
$30 by itself ( just the dual crystal)
$40 full kit (dual crystal, wiring harness, socket, 3-pin NH connector)
Dual crystal module designed by @Derick2k
When installed and used in conjunction with Darksoft's CPS1.5 multi this device will automatically select and use the correct clock speed for the game being played. Either 10mhz or 12mhz.
How to install:
Step 1 --- verify your A-board is working correctly with the multi.
Step 2 --- desolder the crystal from the A-board.
Step 3 --- either install and solder the socket or directly solder dual crystal module in place of the old crystal. There is an arrow that indicates pin 1 on the module.
Step 4 --- desolder the three pin connector for Dash, Reset, and Q sound from the top of the multi. It is located next to the SD card slot. Proceed to install the 3-pin NH connector on the bottom side of the multi as shown in the picture below.
Step 5 --- Take the wiring harness provided and identify the two longer wires. One is Reset and the other is Q Sound. Solder them on the underside of the A board as shown in the multi manual or for a cleaner install use the two topside solder points from the pictures below. On this harness shown Reset is yellow and Q sound is green. Wire colors may vary.
The provided wires are long enough to reach the underside comfortably however feel free to trim these wires shorter I'd using the above solder points for a cleaner install.
Step 6 --- plug the 5-pin connector into the dual crystal module and the 3-pin connector into the newly installed 3-pin connector.
Your install should look like this now:
It is helpful to lay the multi pcb next to the A-board when plugging in the 3-pin connector to minimize stress on the dual crystal module, especially if using a socket.
The socket is great if you may want to revert your pcb to stock but if the install is meant to be permanent I recommend directly soldering the module to avoid accidentally shaking the module loose.

. If you have doubts about desoldering the old crystal have someone else do the mod.
