Hardware disassembly report for Motorola hardware hackers.

This indicates socket U14 held a cryptographic S-box lookup table for decrypting the Stardust keystream.
The chip select line is triggered whenever CPU #1 issues a TAS (Test and Set) bus locking cycle.

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.
