Playcable missing chip?

I have a big doubt looking inside my Playcable. There is a red empty socket (sorrounded by a red rectangle in the picture), is there any missing chip? I never plugged it into my Inty, I want to be sure that there is nothing missing.

It seems that the MCM411XXXXX chips are RAM, the the empty socket could be firmware?

Thank you for you help.

I'd say it's a general instrument rom chip, 40 pin, 10 bit similar to the exec chip. It would have the code to build the titlescreen and menu. I think it would also handle the address and bus decoding for the ram chips. My guess is that if you pluggd this into an Intellivision you would get a black screen. If it were complete I think you would get a standard exec titlescreen and nothing more.

Are there five mcm4116 ram chips? That would be 80k bits or 8k x 10 bits.

With or without the chip. The Playcable is without use nowadays.

You should plug it in and see what it does; we could be wrong about the rom chip. I think most of the code for building the menu and the music is downloaded anyway.

I'm not much of a collector, would a collector pay more for one that produces the initital titlescreen over one that doesn't.

Yes, blank screen, the missing chip is the main controller.

Yes, there are.
