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? -- Mathieu Nakamura -- Royal Institute of Technology, Stockholm "Marcus is not one man."
