Recently, I have the GamePlan MPU board in production and selling on the Pinside store.
Now, I am adding a replacement board for the lamp driver.
This board only replaces the LDU-2 (if anyone knows which games exactly use LDU-2, please let me know).
It is also licensed by GamePlan like the MPU.
And I added the anti-flickering to the circuit, so that you can add modern bayonet LEDs to your game.
I only have 3 to sell at the moment, more will arrive in late August.
