3DA
3DA was an alliance formed between The Santa Cruz Operation and Hewlett Packard in September 1995. Its purpose was to unify SCO's OpenServer product, UnixWare, and HP-UX from HP; the resulting product would then become the de facto Unix standard for both existing x86 systems and the upcoming IA-64 processor architecture from Intel.
In September 1996, SCO announced that they were offering a "code-level preview" of the system, codenamed Gemini.
By 1998 the alliance had ground to a halt, setting the stage for Project Monterey.
