OpenBSD/hp300

History and Status:

OpenBSD follows in the footsteps of 4.4BSD by supporting the hp300; most types of machine are supported with 68020 or better processors, along with SCSI and HPIB storage devices.

OpenBSD/hp300 runs 8k pagesize executables natively (the first operating system for the hp300 to do so), maintaining the standard binary format used by all other OpenBSD m68k platforms.

Supported Hardware:

• CPUs:
  • 68020-based: 318, 319, 320, 330, and 350.
  • 68030-based: 340, 345, 360, 370, 375, and 400¹.
  • 68040-based: 380, 425¹, and 433¹.
• Disks:
  • Most HP-IB/CS80, including: 7912, 7914, 7933, 7936, 7937, 7945, 7957, 7958, 7959, 2200, and 2203.
  • SCSI-I², including magneto-optical and CD-ROM.
• Tape drives:
  • Low-density HP-IB/CS80 cartridge: 7914, 7946, and 9144.
  • High-density HP-IB/CS80 cartridge: 9145.
  • HP-IB/CS80 1/2": 7974A, 7978A/B, 7979A, 7980A, and 7980XC.
  • SCSI: HP DAT, Exabyte, and SCSI QIC drives such as the Archive Viper.
• RS232 interfaces:
  • 98644 built-in and add-on card single port (dca).
  • 98642 4-port (dcm).
  • 98638 8-port (dcm).
• Network interfaces:
  • 98643 built-in and add-on LAN cards.
• Displays:
  • 98544, 98545, and 98547 color and monochrome Topcat.
  • 98548, 98549, 98550, and A1416A color and monochrome Catseye.
  • 98700 and 98710 Gatorbox.
  • 98720 and 98721 Renaissance.
  • 98730 and 98731 DaVinci.
  • A1096A monochrome Hyperion.
• Input devices:
  • General interface supporting all HIL devices: keyboard, 2 and 3 button mice³, and ID module.
• Miscellaneous:
  • Battery-backed real-time clock.
  • 98624 built-in HP-IB interface.
  • 98625A and 98625B `fast' HP-IB interface.
  • 98658A built-in and add-on SCSI interface.
  • Printers and plotters on RS232 and HP-IB.
  • SCSI autochanger.

¹ 400-series machines configured for Domain/OS are not fully supported, notably, the keyboard doesn't work and the ROMs must be in HP-UX mode in order to boot the system.
² SCSI-II drives are known to work, though this may require changing a jumper on some drives. See your disk's documentation for details.
³ Serial mice connected to a HIL to quad converter are also known to work.

Notable Unsupported Hardware:

• SGC bus on the 425e, and all associated displays.

Snapshots are made available from time to time.
