The CoCoVGA button board carries a mini DIN socket for the DIN-to-HD15 VGA cable included in the kit and two buttons for controlling features of CoCoVGA. Although the installation guides describe how to drill the 5 holes necessary to install this board inside the system case, some CoCoVGA users may prefer to keep their installations easily reversible to stock and/or avoid drilling holes to mount this button board. If the button board ribbon cable can be routed out of the computer case (perhaps between case halves or out another rarely-used port opening in the case), then it may be protected in a 3D-printed case.
Below are examples of button boards installed inside system cases and externally.
Internal button board - installed inside computer system case
External button board - protected within 3D-printed case
