I tried replying attaching a couple pictures, but I did not see it come through. I'm guessing maybe because of the attachments being too large. I posted pics of the chips in question here: https://missilecommand.org/misc/1101_1011_RAM.JPG https://missilecommand.org/misc/1011_1101_RAM.JPG See attached pics. 1101 were Intel's first RAM. The top ones in the pics I think are National Semiconductor brand. The bottom ones, no clue. I suppose they could be 1101's too and someone made the mistake of putting the 1 in upside down on the stamp (see middle bottom). I'm having a hard time finding anything definitive on 1011 RAM, so maybe that was the case.

Anyone know of any device or any way to test 1101 RAM and/or 1011 RAM?

What manufacturer and date code? I don't recall that number offhand...
