I have for sale one working Monarch GXL-4 Pong.
This would be a good candidate for a composite mod because as you can see the image via RF is troublesome on modern tv's.
Has a AY-3-8500 chip and a instruction for the mod can be found here : https://mrpjevans.com/2014/05/binatone-composite-mod/
This is ofcourse a different system but should work just fine.
Comes with a dutch manual which has some writing in it and a box (although it has seen better days).
Asking 7 euro's + postage
