10*33644Sbostic  * Standalone definitions peculiar to vaxen:
11*33644Sbostic  *
12*33644Sbostic  * The mba devices in the standalone system are addressed as
13*33644Sbostic  *	type(mba, 0, drive, partition)		(disks)
14*33644Sbostic  *	type(mba, formatter, transport, file)	(tapes)
15*33644Sbostic  *
163266Swnj  * The mbadrv macro gives the address of the device registers
17*33644Sbostic  * for the specified unit.
183266Swnj  *
19*33644Sbostic  * The uba devices in the standalone system are addressed as

21*33644Sbostic  *	type(uba, formatter, transport, file)	(tapes)
22*33644Sbostic  *
233266Swnj  * The ubamem macro converts a specified unibus address (ala pdp-11)
243266Swnj  * into a unibus memory address space address.
