The unit is a Hewlett Packard HP-HIL ID Module 46084A. It has the older style HP keyboard and mouse interface ports. It is a computer bus used by Hewlett-Packard to connect keyboards, mice, trackballs, digitizers, tablets, bar-code readers, rotary knobs, touch-screens, and other human interface peripherals to their HP 9000 workstations. The bus was in use until the mid 1990s, when HP substituted PS/2 technology for HIL. The PS/2 peripherals were themselves replaced with USB-connected models.
