The MPU on my Baby Pac has suffered from the acidic destruction of a leaky battery and appears to be beyond repair. Does anyone have a working AS2518-133 MPU board gathering dust?
If no one on here has one for sale, you can always pick up one of those "Ultimate MPU" boards as a last resort if you want to lay down the cash. Marcospecialties has them for $199, and your Baby Pac is on the list of games the board will work for.
