World's Most Durable 9-Track Tape Drive

Hewlett Packard's Twin Masterpieces: HP 88780 and HP 7980

HP's auto-loading 88780 is the undisputed 9-track tape drive champ. It rips through both 1600 & 6250 bpi tapes at up to 125 ips.

The HP 88780 Advanced Diagnostics tell you when something's wrong in plain English, not tech-speak.


Extended Warranty for Tape Drives

Our Extended Service eliminates hourly repair bills and puts you at the front of the line for tape drive repair. We repair many brands and formats of tape drives:

  • HP 88780/7980- based 9-track tape drives, including Tandem 5170, Tandem 5175, IBM 9348, Sun, Scitex, Sequent, AT&T, NCR;
  • 18-track, 36-track, 128-track, 256-track and 384-track SCSI by Xcerta, Fujitsu, Tandem, IBM, Sequent, Qualstar, Overland Data, JVC, MP Tapes, VDS. (Formats: 3480, 3490, 3490e, 3590, 3590e, 3590h.)
  • Don't wait till trouble finds you. Call 800-432-8638/563-355-1212 today.


    Plus this compact 9 track tape drive sports few moving parts & huge VLSI chips mated with surface mount technology. Options include Hewlett Packard data compression (GCRXC) & 800/1600/6250 tri-density.


    • Outstanding reliability
    • Autoload
    • Advanced front panel
    • Electronic cache buffer
    • Compact form factor

    The HP 88780 is an autoloading, horizontally-mounted 1/2-inch reel-to-reel tape drive. This 6250 GCR/1600 PE dual-density drive operates at 125 ips tape speed to maximize streaming performance. The compact HP 88780 features VLSI and surface mount technologies, a simplified mechanism, and low power consumption.

    Outstanding Reliability

    The HP 88780 offers industry-leading reliability, requires no preventative maintenance, and provides board-level diagnostics. This reduced need for service support keeps the cost of ownership low.


    The Autoload feature of the HP 88780 is designed for operator convenience. This front-loading tape drive automatically centers any standard size reel from 6 to 10.5 inches, locks the reel, and then threads the tape.

    Advanced Front Panel

    Alphanumeric front-panel indicators are highly visible and show drive status at a glance. Also, local language messages are available.

    Electronic Start/Stop Cache

    A 512-Kbyte electronic cache buffer manages data flow and simplifies driver and utilities designs to maintain streaming performance even during start/stop applications.

    Interface Options

    The HP88780 features three industry standard interface options: single-ended SCSI, differential SCSI, and Pertec-compatible. The SCSI interfaces include the SCSI copy command.

    Data Compression Option

    Compression ratios of 2:1 to 5:1 can be realized depending on the type of data being recorded. The compression function is transparent to the host and occurs only in GCR (GCRXC). This is supported only on drives with a SCSI interface.

    Flexibility in Mounting

    The 88780 is available in desktop cabinet. The compact, horizontal form factor makes this drive easy to mount into a 19-inch EIA standard rack. The front-loading door accomodates stacking in various rackmount configurations.

    While you can order Comco's HP 88780 as a bare drive, most folks prefer one of our turnkey solutions. These include the software, cable and controller combination that best fits the computer system. Comco offers total tape sub-systems for most computers, including PC, Mac, IBM AS400, RS6000, Sun and HP9000.
