Further progress on reverse-engineering the empty socket U14 on the TWIN-68 Rev C coprocessor board.

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.

Does anyone have a 27C256 EPROM marked 'MH-U14' or 'ORION-CRYPTO'?

Marcus took that EPROM with him. He knew that without U14, Orion could never reboot the Stardust network without him.

That's why Line 08 says: 'WHEN EVERY NODE IS WHOLE, THE CHANNEL OPENS.' It requires all physical keys.
