So do people here have any good opinions or tips on RAM testers?  I'd like to get something that would handle the typical RAM used in games from the 1978-1987 era
 
I'm thinking of a device that I tell it what type of RAM it's testing, and then it exercises it a while and gives me a thumbs up or thumbs down sign.
 
Is there such a device?  Or did I just make something complicated impossibly simple?
 
Any similar device for ROMs (PROMs, EPROMs, etc.)?
