 * The mba devices in the standalone system are addressed as

 *	type(mba, formatter, transport, file)	(tapes)
 *
 * The mbadrv macro gives the address of the device registers
 * for the specified unit.
 *
 * The uba devices in the standalone system are addressed as
 *	type(uba, ctlr, drive, partition)	(disks)
 *	type(uba, formatter, transport, file)	(tapes)
 *
 * The ubamem macro converts a specified unibus address (ala pdp-11)
 * into a unibus memory address space address.
