Hewlett-Packard 9122C Disk Drive

The HP 9122C is an external floppy-disk peripheral documented for HP-IB systems. The owner manual is the controlling reference for its disk support, setup, addressing and host-specific operation.

IDENTIFICATION NOTE: Do not treat the 9122C as a generic PC floppy enclosure. Confirm the complete suffix, installed drive configuration, supported media and required host software from the owner manual.

Model specifications

Catalog subcategoryExternal floppy mechanisms
Exact modelHewlett-Packard 9122C IEEE-488 floppy disk drive
Mechanism / media3.5-inch flexible-disk system; exact mechanism configuration, media types and formatted capacity should be matched to the model manual.
Host interfaceHP-IB (IEEE-488 / GPIB) connection; configure the bus address and cabling for the intended HP host.
Disk formatHP-system disk formats documented for the 9122C; do not assume that PC-formatted media or arbitrary IEEE-488 software can use it.
Host compatibilityCompatible HP systems with appropriate HP-IB hardware and system software. Verify support in the host-specific manual before connecting or formatting media.

Model-specific compatibility checks

  • Use the 9122C owner's manual to identify the exact configuration and supported system family.
  • Set HP-IB address and bus termination correctly; avoid double-terminating an already-terminated endpoint.
  • Identify disk format and file system separately from the physical 3.5-inch media size.

Preservation and service notes

Record drive configuration, address switches, host model and software version. Follow the model's service instructions for cleaning and repair; do not substitute generic PC alignment assumptions.

For archival work, capture provenance and retain disk images in the original format before conversion. Keep test writes away from source media.
