What is this thing?

[TacticalAvocado]

EDIT: It may be a discrete logic chip, i am about to confirm or deny it on the EEVblog Forum.

 

 

I found this in a box of my grandpa's old stuff (I can't ask him what it is because ashes don't talk) and im trying to figure out what it is. Sorry if the pictures arent great.

Why are you going through a dead person's stuff?

Probably because they're not alive to go through it anymore, so someone has to.

Isn't it still rude though? IDK honestly.

Since he's no longer among the living, I'd say it doesn't matter much if people go through his stuff or not. If nobody ever went through or took stuff that used to belong to people who are now deceased, think of all the stuff that would be everywhere, never being touched or used again. Very wasteful.

 

I've gone through some of my great grandfather's belongings after he passed away, some of them had little/no value to my great grandmother (still living), so she let whoever wanted said stuff have it, and had no issue with us going through it.

Not sure what the chips say, and it's just a book that he gave me while he was still alive, i think there may have been a cd in it somewhere at one point.

Because whatever i didn't take was most likely going in the trash since my grandma has no use for it, i think of it as carrying on the legacy.

IT may be some sort of discrete logic chip, i'm am about to figure that out, ill have some better pictures eventually

[TacticalAvocado]

Not sure how good this picture but here's one of the chips.

[DannyRyu]

welp, I tried couldn't even find out who made the chips on the site,

I counted 50 pins on the gold pins if that helps any, good luck

Fairchild 7404 IC inverter?  That's definitely the Fairchild logo.

Image quality is potato.  Is there any text on the PCB itself or the 52-pin connector?

[DannyRyu]

The middle part might be called a 50 pin Winchester connector, as for the rest I don't know atm

[MadModder]

It looks like an old SCSI connector. My "guess" would be for either a drive, or printer.

[0xNika]

It looks like a bus terminator you would put on an unused bus to reduce noise by preventing a signal from being reflected.

 

EDIT: After a bit additional googleing I'm not sure anymore, that's one strange connector... It seems to be this thing, a military rack and panel connector.
