All the adapter boards were installed. Each board was installed with a hammer, nails, and standoffs. Standoffs may not have been necessary but they do provide clearance for the wires. Attaching the boards with nails was not ideal since they cannot be taken out easily but screws that diameter were not readily available.

Installation of the buttons was straight-forward. Each button was installed in the same orientation so wiring would be simple. Plastic nuts on each of the buttons were tightened with a specialty tool for attaching arcade buttons. This tool was invaluable when installing forty-eight buttons in row.

Fifty switches arrived in the mail in time to be installed. They replaced the mismatched switches used during the interim. Installing each of them was a fast process since arcade buttons were designed to be quickly serviceable.

Replacing old switches

Since an image of the whole 8Gb card was recorded, it was a simple matter to make three more copies, one for each of the octaves. The file has yet to be uploaded.
