About NetBSD/acorn32

NetBSD/acorn32 is a port to ARM- and StrongARM-powered Acorn RiscPC compatible machines and is maintained by Reinoud Zandijk (). The first formal release of NetBSD/acorn32 is 1.6. In earlier releases of NetBSD, these machines are supported by NetBSD/arm32.

The port first saw light as RiscBSD in 1994 and was later transformed into NetBSD/arm32. In 2001, the arm32 port was split into separate ports for the various supported hardware types. NetBSD/acorn32 was one of these.

Supported Computer Systems

These are systems made by various computer manufacturers for which support as a whole exists.

Earlier ARM-based Acorn machines are supported by NetBSD/acorn26.


Core processor support was written by Mark Brinicombe (most of it) and Neil Carson (some of libkern and pmap, floating point emulators and libraries).

Support for Acorn platforms was written by Mark Brinicombe (most of it) with help from Scott Stevens (various device drivers), Melvin Tang Richardson (VIDC console), Mike Pumford (EtherH driver) and Andrew McMurry (Acorn FileCore filing system).
