True ... is that the program or personality chip. I know it needs both... not sure exactly how they all work. Still really new to the E machines.... but getting a hell of an education with the help of Yall on NLG .... I love being here. :dancing_2:

ok ... since it is missing these items ... what do you want for it ...  really. It will not work at all without a ram board... the chips can be burned to match the machine, but without the ram board.... its missing the major component of the board, besides the program... which I have mentioned... can be burned. The ram board needs to be there for it to function. If I am misinformed ... more than glad to be enlightened on this.

The 4 empty black 24 pin sockets are where the game software eproms go, I guess they would be called the Personality eproms. I think they are 2kx8 size, like a 2516 or 2716 eprom maybe. Not all 4 sockets are used by some games. The larger 40 pin black socket is where the 2650 cpu chip goes. At the top corners of the board are a couple of green sockets, these are not for chips, they are for ribbon cables that connect the mpu board to other boards in the machine, like the I/O board.
