NEC PC Engine Controller PI-PD6 Operation Unconfirmed

Thank you for looking! (^.^)
This is a listing for a TurboPad controller for the PC Engine Duo.

I don't have the main unit at home, so I can't confirm its operation, but it was working before.

I disassembled the controller for this listing, cleaned the exterior, and finished it with a plastic cleaner.

The interior has also been cleaned with alcohol.
Contact restorer has been applied to the controller terminals.

The exterior has some minor scratches due to its age, so please refer to the images. m(__)m I believe it is relatively clean. m(__)m

As this is a used item, please refrain from purchasing if you are sensitive about condition. m(__)m
Also, please refrain from purchasing if you are unable to provide a receipt evaluation on the same day you receive the item. m(__)m

Thank you for your consideration. (^.^)
