 Where the ABC had played around with the previous season's 45-minute format by splitting the episodes in half, with Season 23 they moved the show to an early Saturday evening slot and edited two 25-minute episodes together.So the fourteen episodes took only seven weeks to get through and once the marathon tale was finished the ABC retained the timeslot to continue, in the same two edited episode format, from where they'd left off at the end of 1986 with Tom Baker repeats.In September 1987 the program was moved to 1pm Saturdays, sticking with the two episode format for another six weeks.
