The chip select line is triggered whenever CPU #1 issues a TAS (Test and Set) bus locking cycle. This indicates socket U14 held a cryptographic S-box lookup table for decrypting the Stardust keystream. Did Marcus take the decryption EPROM with him when he left the lab? -- Bruno Kang Tape trading list upon request. SASE required for international mail.
