Tracing the address decoder lines on the motherboard reveals what was supposed to be in socket U14.

Without U14, the board can track the 14.2 Hz carrier, but cannot descramble the binary payload of Nodes 11 through 14.
Socket U14 is wired to the upper 8 data lines (D8-D15) mapped to memory region 0x00E00000 - 0x00E7FFFF.

Did Marcus take the decryption EPROM with him when he left the lab?

Marcus took that EPROM with him. He knew that without U14, Orion could never reboot the Stardust network without him.
