Eprom Ecu{how do i tell if i have one}

[1990Gst6bolt]

I have a 1990 gst and i was wondering how to figure out if i have an eprom ecu. I was told it had one when i bought it but i am not sure. Are there any numbers i can look for on it to make sure. I was told that they were really rare in those cars but i am not sure about that either. Thanks
