I installed three switches and reassembled it. Getting the floppy drive plastic to pop back into place was a pain.

The top switch is momentary reset, then latching speedup, and latching Tandy graphics.

Interesting things happen when toggling the Tandy switch during games. Well, not that interesting, but mildly entertaining in that it can enable and disable the "blinds" effect on-the-fly.
