I'll back that up. The first "had a job to do" program I ever wrote, in
1978, was for a video production helper, laying a new digital academy
leader on a finished commercial, intended to function with an automatic
station break machine. This was at KRCR in Redding CA.
I used a cosmac super Elf, buying its case and an s-100 backplane, built
the video board and added a then $400 for the kit 4kx8 static memory
board to the cosmacs 256 bytes and the interface to a Sony 2850 3/4"
u-matic tape machine it was controlling.
I went on down the road looking for greener pastures after their long
time chief came back to work from the heart attack he had 2 weeks after
I was hired. I had no more contact with the station until '94 when I'd
taken 2 weeks to visit an aunt in Salem OR who was fading. Calling to
catch up, I found that in 94, 14 years later, my program was still in
use many times a day. In a television stations control room, thats
amazing, because while the technology used to play that commercial is
constantly changing, the need to do that job accurately hadn't.
And after scareing Microtime out of their shorts when I found the bare
beginnings of such at their booth at the annual NBA shindig in Vegas the
following year, and mentioning to the bow tie in the booth that I had
already done that, only better, it had dissappeared an hour later and
was never admitted to exist ever again. And no one else has ever
attempted to do it unless they did their own version in house and kept
it quiet.

I don't recall I needed to do any muls or divs, but did do some bit
twiddling. My version of the time code was actually better than drop
frame for tracking wall time. Not that it mattered over the maximum of 2
minutes and 10 second duration of laying down that new leader and the
audio tones on one track of the audio that tied the tape to the station
break machine. But I figured if a had to do it, do it right. :) FWIW, I
still have 2 audio carts filled with backups of that program and a type
written printout of its program on the top shelf of the bookcases on the
walls of this room. My man cave. Memories of times past...
