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. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- Anja Oliveira Tape trading list upon request. SASE required for international mail.
