Jumper Array Summary
Tables 4-13 through 4-16 show a summary of the functions for each pin of

pering a socket group for devices not found in the jumpering tables, and also,
which signal appears on each jumper pin and what pins they can connect to
on the 32-pin sockets.

In Tables 4-13 through 4-16, "From" indicates the source of the signal, and
"To" indicates the destination of a particular line.
