In which city is this company headquartered that uses the HIL bus to connect keyboards, mice, trackballs, digitizers, tablets, barcode readers, rotary knobs, touchscreens, and other human interface peripherals to their workstations?
HIL bus The HP-HIL ("Hewlett-Packard Human Interface Link") is the name of a computer bus used by Hewlett-Packard to connect keyboards, mice, trackballs, digitizers, tablets, barcode readers, rotary knobs, touchscreens, 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.
HP-IL The HP-IL ("Hewlett-Packard Interface Loop"), was a short-range interconnection bus or network introduced by Hewlett-Packard in the early 1980s. It enabled several devices such as printers, floppy disk drives, tape readers, etc. to be connected to programmable calculators such as the HP-41C, HP-71B and HP-75C/D, the 80-series and HP-110 computers, as well as generic ISA bus based PCs.
