scanning of books, magazines, ads and letters • Re: BBC Master 128 Circuit Schematics (Remastered PDF) Mainboard and keyboard

IC40 Pin 2 is labelled as blank but on the MDFS scanned schematics it's pin 3?

Another small bug, IC11, the 146818 cmos chip, pin 16 should be pin 18

Transistors Q11 Q13 are PNP transistors in the diagram they are shown as NPN and are connected in reverse (emitter and collector should be swapped around) to what they are in a BBC master.
