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).

Supported System Models

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

040turbo and 060turbo are also supported for X68030.

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.

Not Yet Supported

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

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