Processor Restrictions

The MicroVAX must be part of a valid DS-6x0Qx-Ax MIRA configuration.
Only hardware options supported within a BA23 environment are valid.

Other Hardware Required

This software requires the special MIRA failure detection and switching 
hardware which is available with the DS-6x0Qx-Ax standard configurations.

The use of the DCLOW function requires the following minimum revision
levels of the following modules:

M7763 (MIRA Logic Module) Revision E1
M7764 (MIRA Dispatcher Module) Revision E1

Note: Later revisions (E1) of these modules should not be used with
      revision D.

Block Space Requirements (Block Cluster Size = 1):

 Disk space requirements for installation:       3800 blocks
					        (1945.6K bytes)

 Disk space requirements for use (permanent):    800 blocks, excluding event log
					        (409.6K bytes)

These counts refer to the disk space required on each system disk. The
sizes are approximate; actual sizes may vary depending on the user's 
system environment, configuration and software options selected.
