==== TODO : refactor of Parrot PAL signal ====
I found a running 15kHz TV, with [http://github.com/mist-devel/mist-board/blob/master/tutorials/soc/lesson11/lesson11.png mist-board tutorial lesson11 Parrot PAL] running fine, but not my CoreAmstrad. It's the same TV I used some years ago at festival with original CPC. I have to refactor Parrot tutorial and adapt it on CoreAmstrad in order to generate a better TV signal quality.
=== DONE : CRTC1 ===
