Apple produced one generation of all-in-one connector for Audio, Apple Desktop Bus (ABD) and Apple 15-pin video called the Integrated Desktop Cable, designed for use with Apple Audiovision Monitors. There were two converter cables, codenamed Cannelloni (290-0796-A) IDC - 15pin, and Calimari (IDC breakout). This one is Calamari, because it looks like a squid.
