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.
- 310 and all other 68010 based systems.
Snapshots are made available from time to time.
