The clock card
The clock card generates the main clock signals used throughout the console. On other boards there
are a few local clocks used, for example, for the serial Rx and TX connection to the remote CPU.
This table shows the signal flow from the clock card to the various boards in the D8B. The clock card
fits into connector J23 on the backplane board. From there, the signals are distributed to other boards
either by ribbon connectors, or using the backplane’s buses to the Tape cards, FX cards, and Digital IO.
Have a look at the schematics/pcb layouts of the clock card. The last page of that chapter has a pcb
layout with traces and some signals and voltages marked. Also refer to the connectors chapter for more
details of each connector mentioned in the table below.
