H8 SYSTEM SUPPORT I

    The H8 System Support I board combined many of the most often desired "extras" in an H8 Heathkit Computer system. Most of these features don't take up enough board space to justify an entire board devoted to performing specifically that function. For example, if every function that is performed by the System Support I were put on a separate board, it would take all the slots! By integrating all these functions into one multi-function board, it will conserved H8 backplane slots, power, and cost.
