<b>Warning!</b>
<b>Multiple Amstrad/Schneider peculiarities have to be kept in mind:
* The numbering on the CPC664/non-German CPC6128 is exactly the opposite of that in the Shugart standard(Shuhart 1 = CPC 34, Shugart 2 = CPC 33 and so on)* The Schneider CPC6128 manual is a 1:1 copy of the Amstrad CPC6128 manual, although the Centronics connector would need to be mounted top-down in order for the plug numbering to match the pin numbering as shown in the manual, which it isn't.Thus, the pin numbers in the manual mismatch not only mismatch the Shugart standard, but also the plug. E.g.: Pin 2 1 on the pin out in the manual and in the table below will be numbered 13 36 on the plug and 33 34 according to the Shugart standard.
* For a maximum confusion, Amstrad has completely changed the pin out numbering on the 6128plus. Here, the numbers on the connector were rotated in order to match those of the plug, but still they do not match the Shugart standard: Pin 1 on the 6128plus is wire 2 of a Shugart-compatible cable, so that wire 1 cannot be connected at all and all signals are shifted by 1.

<h2>For these reasons it is useful not makes sense to use forget about the entirely useless numbers from the CPC manual at all, but numbering by Amstrad/Schneider completely and only to keep in mind where wire 1 of a proper Shugart cable belongs to, relative to a standard numbered plug!</h2>

¹: Assuming you are using a cable which is made to match the Shugart standard on the floppy side.<br>
²: Original cables from Amstrad/Schneider had blue wires to mark pin 1 (which is pin 34 in Shugart standard).<br>
³: Although it might look like it, /RDY and /DSKCHG are not compatible. The CPC expects the drive to become ready (=0) by itself, while the DSKCHG signal stays high until confirmation through the PC, so the drive will never become RDY.<br>
^4: Due to the first signal being on pin 1, there is no pin left for the first wire of the floppy cable (usually red). You can just cut it off, it's just another GND.
