Changes
Signal names in simple brackets show the meaning the signal has today.
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 (Amstrad CPC enumeration) exist on Schneider CPC6128 only due to the use of a 36pin Centronics connector.<br>For a maximum confusion, Amstrad has completely changed the pin out on the 6128plus
