A16 CASTING MOTHERBOARD ASSEMBLY 05340 - 60015
A16 is a six layer interconnect board used to interconnect assemblies A4 through A15 and also to
provide connections to other points in the counter. The symbol denotes a feedthrough point.
For example, the inhibit signal connects to
XA10(10), XAll(lO), and XA12(10). The signal is
used by A10 and A12. The connection at XAll(10) is for convenience only and is not used by All.
Since multilayer construction is used for A16, extreme care should be used when unsoldering
wires, connectors, and jacks. Use the minimum amount of heat necessary to unsolder parts.
When replacing the printed
- circuit connectors, clip off the connector from the top of the board,
then unsolder each pin.
Care should be taken when connecting cables to
J1 through 57.
Use a straight on motion for
mating the connectors.
