I took a chance and won these in a lot on ebay. The pcbs are the same as the normal release. Is there any way to put a date on these eproms or CHR Ram? Any reasons to believe these are not real? Thanks.

It's kinda weird to see a unrom proto not on a proto board but otherwise nothing looks out of place.

The eproms will have date codes that give you an earliest possible date but your pics are too low res to read them.

Yeah i don't know why the resolution uploaded like that. I assume the format be YYWW?
It reads  
JAPAN  7202
the other is
JAPAN 8702
Would an eprom be from 1972? 

you are not gonna find an eprom from 1972 in that size being the first one was invented in 1971. It seems suspicious to me because UNROM games had their own board, so it seems weird for me. I think the easiest way would be to look for differences. I can't comment on the CNROM game though.
