SB-300 (HARDWARE_REV 2) Bally/Stern Arduino adapter kit

This kit will work with all of the same games as our original Classic Bally/Stern Arduino adapter board kit, plus it has one added feature: It supports using the Arduino BSOS to control the SB-300 sound board used in 21 classic Stern pins starting with Meteor (September 1979).

You need this board ONLY for one reason: You intend to make or use new Arduino software that controls the original SB-300 sound board for sounds. If you intend to use a .wav trigger board for new sounds in your classic Stern, you DO NOT need this board. This is true even if you intend to dual-boot your pin to use the SB-300 when the original factory code is selected. You can use our original Classic Bally/Stern Arduino adapter board kit instead, and save two dollars.

If you have any doubt about whether you need this board, send a pinside mail to RoyGBev and I will be happy to answer questions.

To use this board with the BSOS in any game, the define for rev 2 must be set in BSOS_Config.h to compile the code to work with it:


This kit includes everything needed to connect your Arduino Nano to the MPU board. The compact PCB attaches to the MPU board's J5 connector. A jumper selects between the original 6800 and Arduino code versions, and connects to a .1" header, so a remote switch can be added for easy dual-boot operation. The assembled board shown here is installed on a Stern MPU-200.

Compatible with Bally AS-2518-17 and AS-2518-35, Stern MPU-100 and MPU-200, and Alltek boards. Comes with all parts shown here, and assembly instructions.

$31 with free domestic shipping. For international shipping send a Pinside Mail message to RoyGBev.
