About NetBSD/x68k

NetBSD/x68k is the port of NetBSD for the Japanese personal computer SHARP X68000/X68030 series. It runs on some models of X680x0 with MMU and FPU. When you use NetBSD/x68k, you may have to replace your machine settings (e.g. changing MC68EC30 with MC68030).

The History of NetBSD/x68k

The NetBSD/x68k port was started in 1993 by OKI Masaru. At first, it was ported from NetBSD/amiga, and tracked NetBSD 0.9, NetBSD 1.0, and NetBSD 1.1. NetBSD/x68k has been included in the official release of NetBSD from 1.2 onwards.

Since April 2002, Nishimura Takeshi is maintaining the NetBSD/x68k port.

There is also a separate homepage in Japan and a mailing list of NetBSD/x68k.

It is necessary to install Xellent30 or Jupiter-X MPU accelerator for X68000 series.

040turbo and 060turbo are also supported for X68030.

  • X68030/X68030HD
  • X68030compact/X68030compactHD

Supported Peripherals

NetBSD/x68k requires Motorola 680[346]0 processor (with MMU), SCSI board and harddisks, and over 4MByte memory and 100MByte of disk space.

Although the in-kernel FPU emulator can be built into the kernel for 68030-based systems, we recommend to install a FPU.

Peripherals for which support was added in NetBSD 1.5.3 are marked (1.5.3). Peripherals for which support was added in NetBSD 1.6 are marked (1.6).

  • Sharp genuine MB89352 SCSI host adapter and their compatibles
  • Most SCSI devices
  • Built-in floppy drives
  • Built-in frame buffer (both of the text and graphics screen)
  • Built-in Z8530 serial
  • Built-in parallel (Centronics printer interface)
  • The standard keyboard
  • The mouse / trackball
  • NS16550 UARTs
  • Neptune-X DS8390 Ethernet
  • Nereid Ethernet (1.5.3)
  • Mach-2 SCSI host adapters
  • Tsukumo TS-6BE16 extended memory
  • Built-in ADPCM voice synthesizer (1.6)

Not Yet Supported

Hardware that we do NOT currently support, but get many questions about:

  • Old (SASI compatible) hard disk interface

We are planning future support for many of these devices. Contributions are welcomed!
