About NetBSD/sun3
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late 1980's. They were superseded by the sun4 SPARC RISC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.

The RAM column is maximum supported RAM in megabytes.
Sun made a variety of VME bus cabinets with different numbers of
bus slots; ultimate RAM and I/O expansion is more a matter of how
many bus slots there, rather than the particular CPU you have.
The Sun3/80 RAM capacity varies with the boot ROM revision - 3.0.2
allows 40MB, 3.0.3 allows 64MB.
The Sun 3/50 has 4MB soldered on the motherboard;
all RAM expansions for that workstation were provided by third-party
solutions (read "hacks") of one kind or another.
The Sun 3/E is a 6U VME single-board computer intended as an embedded
system component.
The Sun 3/80 workstation and Sun 3/400 series servers are sun3x
architecture machines based on the Motorola
68030 CPU. They were Sun's last design using Motorola
microprocessors, and were somewhat complicated by the fact that the
mc68030 has an integrated MMU in the CPU chip.
Sun Microsystems stopped designing systems with Motorola
microprocessors when their own SPARC CPU design became a commercial
success.
Features of NetBSD/sun3
- Native boot programs for disk, network, and tape
- Automated installation tools (using a "miniroot")
- SCSI drivers supporting DMA, interrupts, and (optional) disconnect/reselect
- Frame buffer drivers compatible with SunOS and X11R6
- Support for the Virtually Addressed Cache (VAC) on Sun3/2XX models
- Storage Module Device (SMD) disk drivers
- Supports most SCSI devices (CD-ROM, disk, etc)
- Diskless (network) boot capability
- Built-in kernel debugger
- SunOS 4.1 Compatibility
Disk and RAM Requirements
Minimum
Normal
Normal + X11
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.
Supported Hardware
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:

- Input devices:
- Sun keyboard (kbd) and mouse (ms)
- Miscellaneous:
- 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.
