Bus Architectures

Series 700 Bus Architecture

Since its initial introduction, the Series 700 has grown enormously in

breadth and ability to be conﬁgured. The ﬁgures shown illustrate the

Series 700 conﬁgured as a workstation, although Model 735 can be

conﬁgured to support additional 735 or 755 workstations as a cluster

server. The Model 770 features multiple GSC+ buses, for versatility and

I/O efﬁciency.

Model 712

Figure B-1, “Model 712 Bus Relationships,” shows the Model 712 bus

diagram, which has capability for up to 2 graphics cards and 2 graphics

monitors (which show up on ioscan as 0 and 1). Core I/O descends from

slot 2 off the system bus, and optional cards show up as slots 5 or 6.

Optional cards include support for IBM TokenRing, LAN, X.25, serial,

and telephony. A third-party card is also conﬁgurable for video and

multimedia capabilities.

Sample Addresses

A parallel printer is likely tohave a hardware address of 2/0/6.0. A disk

might have an address of 2/0/1.5.0, if the SCSI address on the device

itself were set to 5.
