Description
HP A1703-60022 Multifunction I/O Board SCSI Parallel Printer APMUX16 Card
The HP A1703-60022 is a multifunction I/O expansion board providing integrated SCSI, parallel printer port, and APMUX16 interface connectivity in a single card form factor. Designed for HP 9000 series workstations and servers, this board consolidates multiple I/O functions that allow the host system to communicate with SCSI storage devices, printers, and auxiliary multiplexed peripherals from one slot. The bracket is clearly labeled with its three port functions and includes a Term Power LED indicator for SCSI bus termination status.

Applications
The A1703-60022 was used in HP 9000 series workstations and servers — HP's PA-RISC-based systems running HP-UX — which were widely deployed in engineering, scientific computing, and enterprise environments from the late 1980s through the early 2000s. In that platform, multifunction I/O boards like this one provided the host system with access to SCSI storage (hard drives, tape drives, CD-ROMs) and parallel-port peripherals such as printers and plotters, while the APMUX16 interface connected to HP-proprietary auxiliary multiplexed devices including terminals and serial concentrators. These boards remain sought after for maintaining legacy HP 9000 installations, repairing aging HP-UX workstations, or restoring vintage HP engineering systems. The integrated Term Power circuitry ensures stable SCSI bus operation without requiring a separate terminator on the bus.
This HP A1703-60022 Multifunction I/O Board has been inspected and is in good used condition. It was pulled from a working environment where it was in active use and functional. The PCB shows typical handling and age wear consistent with normal service life. The bracket, connectors, and Term Power LED are intact and appear undamaged.
