Multiple Module Cage Configuration
Multiple MVME187s may be configured into a single VME card
cage. In general, hardware multiprocessor features are supported.
cage. In general, hardware multiprocessor features are supported.
GCSR Location Monitor Register
Other MPUs on the VMEbus can interrupt, disable, communicate
with and determine the operational status of the RISC processor(s).
One register of the GCSR set includes four bits which function as
location monitors to allow one MVME187 processor to broadcast a
signal to other MVME187 processors, if any. All eight GCSR
registers are accessible from any local processor as well as from the
VMEbus.

Ethernet LAN (+12 Vdc) Fuse
The MVME187 provides +12 Vdc power to the Ethernet LAN
transceiver interface through a 1-amp fuse (F2) located on the
MVME187. The
