There was also J.A. Lawrence's Mudd's Angels (1978) which featured adaptations of both TOS Harry Mudd episodes, as well as an original novella called "The Business, as Usual, During Altercations," which ends up with Harry Mudd being exiled from the galaxy.
And which was incredibly terrible. It annoys me that the Mudd episodes were left out of the 3-volume anniversary reprint of the Blish adaptations in production order, since I got rid of my copy of Mudd's Angels long ago, so those are the only two adaptations I don't have. (It was later reprinted as Mudd's Enterprise, IIRC.)
