Kenbak-1 Front Panel Question

[OCM]

Does anybody know what what was the purpose of the slot in the top right corner of the original Kenbak? The slot has two screw holes on each side, so obviously something was supposed to be mounted there.

Thanks in advance

John intended to add a card reader for punched cards in that location, but he never got that far.
