To reinstall a board, first check the positioning of the black plastic pin guide to
ensure that the beveled openings are aligned with the receptacles on the
board. Position the board’s leading edge in the top and bottom card guides for
the Testhead slot and carefully insert the board until resistance is felt. At this
time, it is crucial to ensure that the pointed ends of the Patchboard pins are
properly aligned with the receptacles on the board. When the alignment is
correct, a slight “give”will be felt as the pins begin to seat. At this point, place
your thumbs on the white tabs and firmly seat the board. Ensure that it is fully
seated by comparing the position of the rear edge of the board with the rear
edge of neighboring boards.
If excessive resistance is encountered or a high pitched metallic noise is heard,
stop and remove the board or damage to
the pins and/or receptacles may occur.
Repeat the procedure from the beginning.
In some cases, temporary removal of boards
in adjacent slots may be helpful.
