SPS Control Card (SUN820-200)
CARD DESCRIPTION
The SPS control card replaces two Trancon cards and the TranSCSI card. It consists of a
possible five transputers namely, TranSCSI, File Server, Assignments, Automation and
Allocation. The links between them and how they are intended to fit into the system are
shown in the diagram below. The Assignments processor may not be fitted and can be
jumpered out of the Link and ISP chains by fitting J12 (Note U65 and U66 must be removed
in this case). All links shown on the right of the diagram with the exception of the Debug link
are available on the backplane.
