Thunder Board

The Thunder Board was an 8-bit mono personal computer integrated circuit sound card from Media Vision, that had Sound Blaster compatibility at a reduced price. It was widely advertised as “proudly made in the USA”; possibly a reference to the Sound Blaster, manufactured by the competing Singapore-based Creative Technologies.
