SYM-1 6502 Single board computer

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.
6502 MOS 1Mhz CPU (Rockwell)
6522 Complex Interface Adapter (Synertek)
