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. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- Yuki Souza *PLONK* filter active for trolls.
