64-way bus board and service aid in uP systems - a new two-dimensional extension bus with 7 + 2 connectors

64-way bus board elektor december 1983 The first time a microprocessor bus system is used it seems enormous, but before long it begins to seem a bit limited, and then cramped, and finally completely inadequate. So after our first bus with 3 connectors, and the second with 5, we now introduce the new extension bus with no less than 7 connectors, which, unlike its predecessors, is perfectly symmetrical. 64-way bus board and service aid in pP systems a new two- dimensional extension bus with 7 + 2 con- nectors The new Elektor universal bus differs from its predecessors in that it has seven 64-way female connectors, plus a male connector at one end (the "input") and a female con- nector at the other end (the "output"). In addition to this, its upper side (connector side) is copper-clad and acts as a screen. The layout of the board also allows easy interconnection between lines.
