For your convenience, the pin no. are given as specified in the Shugart standard first, followed by the pin no. as assigned by Amstrad and shown in the manual.
Note that pins 35 and 36 (<b>Warning!</b><b>Multiple Amstrad CPC enumeration) exist on /Schneider CPC6128 only due peculiarities have to be kept in mind:* The numbering on the use CPC664/non-German CPC6128 is exactly the opposite of that in the Shugart standard* The Schneider CPC6128 manual is a 36pin 1:1 copy of the Amstrad CPC6128 manual, although the Centronics connectorwould 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 the Shugart standard, but also the plug. E.g.: Pin 2 on the pin out in the manual and in the table below will be numbered 13 on the plug and 33 according to the Shugart standard.<br>* 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.</b> <h2>For these reasons it is useful not to use the entirely useless numbers from the CPC manual at all, but only to keep in mind where wire 1 of a proper Shugart cable belongs to!</h2>
