After doing a few quick checks and then power up unfortunately it doesn't boot.
So now I'm going to see if I can find some schematics and then we're going to start doing some troubleshooting on this system.

Thanks to Jonathan

Update: After replacing the 2114 RAM it now boots.
The 65xx Chips are all okay.
