Inspect each socket carefully, and straighten any bent pins before attempting
installation.
Install the eight pin IC socket at location U1 observing orientation.
Solder.
Locate the sixteen-pin low-profile DIP IC socket. Install the 16-pin
socket at location U2 observing orientation. Solder.
Note:
It is very easy to bridge adjacent pins on these sockets because of
the very close spacing; be very careful when soldering. If bridges
occur, remove them using a solder sucker or solder braid.
Locate the push-action DPDT (double-pole/double throw) switch.
Install the switch at location SW1 on the PC board. The white
switch shaft should face the edge of the PC board. The body of the
switch should be flush and parallel to the PC board surface. Solder.
Locate the spool of insulated jumper wire. Install the jumpers as directed below:
Note:
For the following steps you will need to determine the proper
wire length needed for each jumper. The jumpers will vary from
about 2 inches to 3.5 inches for the longer runs. The wire
jumpers should rest on the PC board, in the area between the red
LEDs CR0 to CR9, and U1, U2 and SW1. Prepare each jumper
by cutting the wire to length. Strip about 1/8” of insulation from
each end in preparation for soldering.
Strip insulation back 1/8-inch from each end.
Install a jumper between points W8 and WI on the PC board. Solder.
Install a jumper between points W4 and WE. Solder.
Install a jumper between points W9 and WJ. Solder.
