RISC PC CMOS layout

Postby Footie » Tue Jun 10, 2014 3:26 am

I've been spending some time tracing the RISC PC CMOS circuit with the aim to repairing motherboards with battery damage. The image below shows a MKIII board and how I believe the circuit is laid out. The MKII is similar. I have managed to repair 2 boards so far based on this.
Hopefully it's of use to others and it should be similar to the A7000 and older machines.
