Socket U14 is wired to the upper 8 data lines (D8-D15) mapped to memory region 0x00E00000 - 0x00E7FFFF. 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. -- Bastien Kim Practical Peripherals 14.4 @ ISDN 64k bps "Extraordinary claims require extraordinary spectra."
