PICTORIAL 1-6
NOTE: You may have been supplied two 6-pin and
two 20-pin sockets or two 26-pin sockets. Use the
steps that match your sockets.
26-PIN SOCKETS
Refer to Pictorial 1-6 for the following steps.
( ) Locate the two 26-pin sockets. Then refer to
Detail 1-6A and cut off the indicated lugs at one
end of each socket.
1. Push the socket onto the edge of the circuit
board next to the data jumpers.
2. Make sure the circuit board is between the
two lugs at each socket connector. Also
make sure each lug lines up with a foil on
the circuit board. NOTE: The socket hole
where you cut off the lugs must be between
foil contacts 24 and 25 as shown.
Detail 1-6A
NOTE: Perform the following carefully. The sockets
are very difficult to remove once they are installed
wrong.
( ) Use the following procedure to install one of the
26-pin sockets on the circuit board:
3. Solder only lugs 0 and 24 to the foil on the
component side of the circuit board. The
other lugs will be soldered later.
( ) Similarly, install the remaining 26-pin socket
on the edge of the circuit board next to the other
socket. Make sure the circuit board is between
the two lugs at each socket connector. Also,
make sure each lug lines up with a foil on the
circuit board. NOTE: The socket hole where you
cut off the lugs must be between foil contact 49
and the nearby corner of the circuit board. Sol
der only lugs 25 and 49 to the foil on the com
ponent side of the circuit board.
