Re: Reimaged New XF551 Disk Drive PCB: eventueller Fehler

Hi, Was sagt denn der Hersteller der Platine dazu? Dropcheck sagt sinngemäß, daß nach der ursprünglich getesteten Platine noch ein paar Anpassungen vorgenommen wurden und daß es unverständlich ist, warum dabei der FDC falsch verdrahtet wurde. Dropcheck will die Platine bezüglich der gemeldeten Fehl...

Are you able to post the PCB files here for your version of the board?

I haven't tried my board with the ROM's installed yet. Will try that later.

I'm not sure how we can have the exact same rev of board (v6.0_B) yet they are different boards!

Pulling the schematic (see attached extract) the pin joint between U2 and U1 doesn't seem to align with the schematic?

Re: Reimaged New XF551 Disk Drive PCB: eventueller Fehler

Interesting when I went to look at cutting the tracks tonight my board looks a little different to your even though we are both rev 6? It might be easier that I just lift the legs of the IC U2 and solder wires directly to the legs of U1 yes? That means lifting legs U2-3,4,5,6,7 and 8 right? U2-3 -> ...

Fantastic!

Can you show a picture of the traces you cut and the jumper wires installed?

Hi All, Sorry for the English. I have been working on the XF551 V6 board without success. I have built two boards and both have been an issue. I was able to put in the wire to allow power but I now read the three transistors on the board are the wrong way around. I will fix that on my board. Are the...
