NetBSD/sun3 is the port of NetBSD to the Sun Microsystems sun3, and sun3x series of computers, which are based on the Motorola 68020 and 68030 CPUs respectively, with a Sun-designed custom MMU. Sun sold these computers as both servers and desktop workstations from the mid to late 1980's. They were superseded by the sun4 SPARC RISC systems, which are supported by NetBSD as NetBSD/sparc.

Supported System Models
See the Supported System Models page.
The following Sun3 devices are currently supported:
- RS-232c Serial ports:
- built-in z8530 SCC as ttya, ttyb (zs(4))
- Sun Video adapters:
- Network interfaces:
- SCSI bus host adapters:
- SMD Disks: (the big, heavy ones)
- Floppy drive:
- Sun 3/80 built-in floppy drive (fdc)
- Input devices:
- Battery-backed real-time clock
If you have a device that's not listed, it might be compatible with something else, or we might have simply forgotten it. If all else fails, maybe you could write a driver!
Note: The Sun VME sc(4) SCSI card is not supported.
