Does anyone have the schematics or know anything about the electronics who control the floppy?

The system cant read or write floppies and the drive has been replaced without any difference.
From what i could see on the circuitboard there are one complete floppycontroller-in-a-chip and three other normal 74xx chips that is all that is connected between the drive and the cpu.

WD1772PH-00-02 seems to be quite hard to find locally too, so if anyone in sweden has one (or an old atari with that chip inside they want to sell) please contact me.

Anyone?

[Ted Olausson]

YES!!!
Now it works again!! Burnt trace inside the multilayer circuitboard...

Regarding the total lack of response: am i the only one in the world now, who can repair optifile???

Have you tried contacting Jean Pierre Lafont?
His new venture:

If he was the original constructor, then Yes we did...
-We got one answer from him and then nothing more

But we also mailed every possible studio/repairplace and everything else that we could think of, but no useful answers from anyone.
-Thats why i had to reverseengineer it to fix it, but now it works again

The original designer and manufacturer was Pierre Antonini.
As far as I know he is living in Canada now.
JP Lafont, like many console manufacturers, used automation systems from Antonini in his consoles.

It would have been much nicer to have all these names a month ago when i needed them, now they are quite useless...
But from what i heard, the original constructor is working at funkyjunk in france.

Pierre Antonini's son is working at Funky Junk.
Pierre lives in Canada and has completely left audio and electronics aside.
