RCIM IV Registers
This section contains the address map and registers on the RCIM IV board.
Note that some registers appear at two places in the physical address space. For these
registers there is an associated
Xregister. For example PCSAT and XPCSAT. The Xregister
accommodates systems with a 64k, rather than the old 4k page size.
