what's this cartridge adapter?

I saw this over on Facebook- it's from a video of a 99/4 playing Soccer.

 

What kind of cartridge adapter is this?

This is one of TI's GROM simulators- when the tv program was made the game had not been put into a module yet. It uses the same sort of GROM simulation that we have in FG99 today using auto-incrementers.

Actually, that particular box is called an EGROM Box. The case is a phenolic plastic. It has a TI console power supply in the bottom and a board on top that acts as a GROM simulator for up to five GROM chips, using two 4K EPROMs per GROM. I have two different versions of the device. Note that this one uses EPROMs and not RAM chips like the GSIM device Ciro pictured (I have one of those too).
