Ex-Bostonian that I am, I can't resist chiming in, even though I can't add much (if any) new info, having left town in '87.
The syndicated TTD was not shown in Boston at all; it was available to those of us who could pick up WMUR in Manchester, NH (the location of my folks' house on a hill about ten miles north of the city afforded us Channel 9's broadcasts.) One night, I just happened to tune in to the season premiere featuring defending champ Thom McKee, in the last stages of his record run. (I think either Providence's WPRI (Channel 12) or WJAR ("Providence's Television Ten") may also have carried TTD.)
The TTD that KrisW73 remembers on then-WNEV (Channel 7) is most likely the brief CBS version.
WCVB (Channel 5) blacked out ABC programming on Saturdays from 8 - 9 PM (including "Super J!" and "Monopoly") to show "Star Trek: The Next Generation."
Channel 27 in Worcester was originally called WSMW. At one point, they were showing reruns of Cullen $25K Pyramid five nights a week; I remember catching Freddie Prinze (Sr.)'s sole appearance. (Hey, this was an era where we rarely saw since - deceased people on game shows, with the possible exception of Wally Cox, who seemed to live forever on nighttime syndie HSq.)
Esoteric Eric, having OT memories of "Uncle" Gus Bernier, WMUR's afternoon kiddie show host / evening news meteorologist, and Bob Fouracre, host of WSMW's candlepin bowling show; talk about a "host-ism," how about a guy whose favorite superlative IS "superlative" (as in "A SUPERLATIVE strike for Charlie Jutras!!!")
