Spectrum e-TEC Dart Machine Motherboard Circuit Board USED 2 * Motherboard * IO Board For repairs or spare parts. These were removed and kept when a friend's dart venue switched from e-TEC to Live. They were working normally before removal. An older Spectrum Elite that was in the same place was working fine, so I think this is also okay, but I haven't been able to confirm it because I don't have an e-TEC machine. Due to the age of the machine, and to prevent parts-swapping, please understand that returns and claims are not accepted. Spectrum e-TEC
