+=== New Super-K Power Box ===
+
+This box is designed to be driven by the Hytec 2256 VME module, or any other source
+of step/direction pulses

+=== Old Power Box for MACRO/Super-K ===
+
+This is a Bud box with a 12V power supply, a PCB and 3 connectors (DB15, DB25 and 20 pin header).
+It provides power switching electronics for a 5V motor.
