What kind of chip is this?

[SLCE30318is]

Dax (built his F20c E30 all by himself) was kind enough to send me an old chip that he had found in his glove box and had used for a while before he swapped the engine on his car.

Neither of us are sure what brand chip it is. Just curious if anyone may know.





Thanks for the help
