Can a ColecoVision 5v Memory Mod be done on a Rev.D (1983) motherboard?

Hmm that's a weird one. If you changed out the DRAM already, then Maybe your VDP took a dump. These can be a pain to get working right sometimes.

Thanks for the detailed pictures, I wish someone would do this for the "doubledown" power switch mod.

I may try this RAM mod later on down the road

Video Display Processor, the main graphics chip. They can go bad.. Search around the forum in the ColecoVision section for more info

I can confirm this mod works perfectly on a PAL Rev D Colecovision board. Since I have the VGA F-18A mod I had to put. an extra socket on the video processor to clear the raised RAM in it's sockets
