I am trying to find any resources about this item. I know that Argonaut made a Ramboy and Rambaby, both regular sized famicom cartridges used to aid in the development of games. I am presuming that this had a similar function. The Argonaut cart had a ribbon connector leading from the cartridge that connected to a pci card.
This ram casette has some headers that I presume was for programming the eeproms, maybe utilizing it like a quick-flash cartridge with some extra RAM for debugging? Wanted to get some thoughts for anyone who worked with original hardware in those days, or might have some knowledge on this subject.

Other variations of this style cartridge I've seen is the the campus challenge 92 and 94 cartridge, as well as the service center top loader control deck tester seen here -

This mold has special cutouts for the various LED's on the deck tester, which is different from the Ram Casette, which has the mold that I've seen on the powerfest 94 cartridge that a friend owns, seen here -
