BDub has previewed a new adapter for the Vectrex that adds impressive stereo audio features. The mod consists of a socket coupler with an audio lead, and is designed to fit between the AY-3-8912 sound chip and the Vectrex logic PCB. There is a commercial seller offering a similar mod, but it is quite expensive and presumably BDub’s simpler solution would be much cheaper to produce.
