Note how the cable turns sharply near the bottom of the Port to take advantage of the
space that will exist between the upper and lower halves of the case. It is easiest to
route the cable with the center section of the case in place on the lower case half.

CPLD. The connector used is very fragile and was not really designed for multiple
insertions, so take your time, but make sure the plug is fully seated in the connector
on the 41CL circuit board.
The two connectors for programming the CPLD and the FPGA on the board are
identical, and plugging the serial port connector into the wrong one will damage the
board. The 41CL circuit board is shipped with a blank plug in the FPGA connector to
prevent accidently inserting the serial connector in the wrong jack.
This step is where the double-sided tape holding the cable in place is useful, as it
keeps the cable from popping out of the channel on the side of the calculator where it
resides.
