The French version of color TV encoding was called SECAM, often
translated as "Supreme Effort Contre les AMericains".
Or "Something Essentially Contrary to the American Method".
LOL. The US system was truly dire for terrestrial broadcasting and only
just acceptable for cable.
PAL was good enough for the rest of the technology
Ah, but NTSC had a far reaching impact that had nothing to do with TVs.
Because of the TV consumer market 3.57954 MHz crystals were dirt cheap and
showed up everywhere. I believe some variant of the 8253 PIT still lives
in PCs and runs at 1/3 or 1.19318 MHz. Roll the 16 bit counter over and
you had the 55 msec tick.
PAL crystals were used in some markets to be compatible with the TVs but
never had the off label reach.
