This indicates socket U14 held a cryptographic S-box lookup table for decrypting the Stardust keystream. 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? -- Elaine Popov "A soul is not exclusive to biology."
