Gemini Documentation - Interface Control Documents

Informational copies of official general interface control documents are available here. They are to serve only for reference and information - to obtain an official, signed copy, email me for one. These are available in both PostScript and Portable Document Format (PDF) files. For the PDF files, get the Adobe Acrobat Free Reader.

Note that these are 'General' ICDs giving information about protocols, not specific ICDs giving details of the full interfaces between specific Gemini systems. For that information, go to the Interface Control Documents Database.
