Re: [hatari-devel] "SECAM" STE's

Interesting.

I see that 31.922046 clock is mentioned in DOIT and Atari-Forum:

Hm, I wonder whether Atari installed the wrong oscillator or someone
else changed it later.

Other French STEs have a 32.084988 MHz crystal oscillator, as can be
seen on these photos:
https://www.exxosforum.co.uk/forum/viewtopic.php?f=51&t=3625,
https://www.exxosforum.co.uk/forum/viewtopic.php?f=51&t=851 and also in
the STE's schematic.

In other word's: I would not change Hatari based on a (presumed)
odd-one-out STE.

Here are photos of the oscillators of the mobo in question. Looks like factory work.
