Years ago I was hell bent on getting something used in the development of video games. Not completely sure why. Of course being a poor high school student without a job my options where limited.
Eventually I was able to obtain these empty ROM boards to satisfy what my crazy brain was telling me to do.
One is for Sega, my guess is genesis or 32x (most likely Genesis) and the other is for Super Nintendo.
I realize their value is proportional to a game actually being on them, but as themselves as a dev tool, what could the be worth being original parts used in video game development.
