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 Sun sold these computers as both servers and desktop workstations from the mid to late 1980's. They were superseded by the sun4 SPARC RISC systems, which are supported by NetBSD as NetBSD/sparc.
Nathan Williams and Jeremy Cooper are the maintainers of NetBSD/sun3.

Supported System Models
See Supported System Models page.
Disk and RAM Requirements
- 4MB RAM, ~80MB disk
- 8MB RAM, 200MB disk
- Normal + X11
- 16MB RAM, 300MB disk
The complete NetBSD sources without objects require 200MB of disk.
To run the X Window System or compile the NetBSD system sources (i.e. development), more RAM and disk are recommended. Good performance requires 8MB of RAM, or 16MB of RAM when running the X Window System.
The following Sun3 devices are currently supported:
- RS-232c Serial ports:
- built-in z8530 SCC as ttya, ttyb (zs)
- Sun Video adapters:
- 1 bpp framebuffer, (bwtwo)
- 8 bpp framebuffer (cgtwo)
- 8 bpp (+overlay) framebuffer (cgfour)
- Network interfaces:
- On-board AMD LANCE Ethernet (le)
- On-board Intel Ethernet (ie)
- VME Intel Ethernet board (ie)
- SCSI bus host adapters:
- On-board NCR 5380 SCSI Bus Controller (si)
- On-board Emulex SCSI controller on sun3x (esp)
- Sun-3 VME SCSI (also NCR 5380 SBC, Sun part # 501-1236) (si)
- SMD Disks: (the big, heavy ones)
- Xylogics 450/451 (xy)
- Xylogics 753/7053 (xd)
- Floppy drive:
- Sun 3/80 built-in floppy drive (fdc)
- Input devices:
- Sun keyboard (kbd) and mouse (ms)
- 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 SCSI card is not yet supported.
