UnitsThe Heritage/1 minicomputer consists of several units. Each unit is a rack-mount multi-cards frame with its own power supply and internal buses. Different configurations are possible by combining different units in a number of possible ways. They can all populate a single rack or arranged in different ones as needed.
Units communicate each others by the mean of a 39-lines bus called U-BUS. Externally the bus consists of two cables ended with D-SUB connectors (37-pins and 9-pins respectively). Cables plug to units in a daisy-chain fashion. The last unit in the chain requires to be terminated by the mean of a two terminator connectors.
Wires in the bus carry either signals or ground. No power is provided through the U-BUS.
