This is a toy my husband played with when he was a child. He played with it a lot, and it has a Showa era feel, so please be aware of that. I have confirmed that it works, and I have replaced the batteries. It's an LSI game machine called "Toryu-Oh" (Stealing Base King) by IC Moritani (MMC), a microcomputer baseball game. It's a retro electronic game from the Showa era. In the center of the main unit, there is a circular screen that simulates a stadium, and there are operation buttons for the offense and defense. When a runner gets on base, you can "steal a base," which is the biggest feature of this game. - Model Name: Microcomputer Baseball - Colors: Orange/Green/White - Features: Baseball game Thank you for looking.
