We just added back in stock the much awaited Data East replacement MPU. We have a limited quantity due to pre-orders from customers who were on a waiting list. If you need one, now is the time to buy before we run out again. Not sure if you should have your existing board repaired or to replace it - we can help you to determine that. In most cases if your current board is "clean" (free from poor previous repairs and acid damage) we can repair it for far less than the cost to replace it. Call us toll free: 1-877-775-5399.
