This pinout description is wrong if we can use the same RGB cable for A1WX, A1WSX, Turbo-R, etc because some pins not correspond.
I said to *not* look at the pin numbers, only the layout:
Don't pay attention to the pin numbers, they are almost all messed, take a look in the pins position, which are correct.
I put both connectors pinouts side-by-side in this image:
I guess now it's clear why the normal cable works in A1WSX.
A picture is better than a thousand words
This should be added to the wiki!
I said to *not* look at the pin numbers, only the layout:
That's what I did.
YS and AV are inverted relative to the RGB cable for A1WX, Turbo-R, etc.
There the question is still unanswered.
I guess I'd better send Europe's most famous Japanese computer refurbisher a mail as he has probably seen a lot of them.
I asked and got an answer. (if you do not use a data recorder) A Panasonic/Sony compatible RGB cable will work on a WSX.
