Conchess Plymate 5.5MHz

It is almost identical to the other Plymate dump, most of the differences are due to changed timing I guess.

hap, I'm a bit confused about your new Conchess driver:
In the previous version the T8 was implemented with 8_MHz_XTAL/2, but now you've changed this to 16_MHz_XTAL/2 !?

Does this mean that the T8 has in fact a 16MHz XTAL, which is divided by 2 for the CPU clock?
Most articles on the internet say "4 MHz (8 MHz Quarz)" for the T8.

There's also a Monarch T24,

and it says: "Taktfrequenz: 24 MHz (12)" (in one of the pictures there's really a 24MHz XTAL!).

So shouldn't the T8 also have an external 8MHz XTAL? But then it would actually run only with 4MHz (and a T6 with 3MHz, etc.).
