15.12 Futurebus+ on DEC 10000/7000
This section describes some of the details of DEC 10000/7000 Futurebus+
implementation.
15.12.1 The DEC 10000/7000 Futurebus+ Bridge
The DEC 10000/7000 platform contains an IOP module which interfaces to the
DEC 10000/7000 I/O subsystem. The IOP supports up to 4 bridges to remote
I/O buses. Currently the supported I/O buses on DEC 10000/7000 are XMI and
Futurebus+. The Futurebus+ bridge on DEC 10000/7000 is implemented in a
distinct Futurebus+ module called the Flag. The DEC 10000/7000 Futurebus+
backplanes are 10 slots. The Flag must be installed in slot 5. Slots 0-4 and 6-9
are available for user Futurebus+ options.
