Atari ROM chips NEC & Intel Bootlegs? anybody know what they are?

[SAVETHEPAST]

I just bought these ROM Chips and PCB boards. Anybody know what they were originally used for? Out of the 43 chips all but 5 work on my Atari 2600. I figured that somebody just made the kit to use at home. One of the PCB's has a switch that says 16/32 some of the chips only play on the 16 and some only on the 32. The Intel chip dates range from 1977 - 1980 and the NEC chips have no dates that I was able to decipher. Anybody have any useful info about what exactly these are?

 

They seem to be all normal common games. I haven't had a chance to play them all, just put them in to see if they worked. I'm not sure if there are any difference in the original games and the ones I have. The ones I have compared seem to have the same opening screen. I listed what was written on each chip below.

Yes, that's a pretty common hack (I have one as well) normally done by ex-employees (where I got mine from) to run production rom sets they pilfered at the time. A trick sometimes as well during that time period was to remove the rom and return the cartridge to the store as defective, keeping them to run in a setup like that.

 

A trivia piece, but nothing ultra valuable.
