23: OpenBSD/arc runs on the machines compatible with the <i>Advanced RISC
24: Computing</i> specification, known as ARC machines, based on MIPS processors
25: and initially designed to run Microsoft Windows NT.
26: Such machines include the long dead Acer PICA, as well other machines
27: manufactured by other companies such as MIPS, Deskstation, NEC, and Olivetti.
28: </p>
29:
30: <p>
31: The ARC specification is extinct, and no new ARC BIOS machines for MIPS will
32: likely be manufactured.
33: Microsoft has announced that it will no longer support MIPS after NT 4.0.
34: OpenBSD/arc used to provide a good alternative to NT.

43: There is currently no one working on bringing this port back to life.
44: The source code is still available in the CVS Attic, and code can be found in
45: NetBSD as well.
46: If you are interested in reviving the arc port, make it work and contact
47: <a href="mailto:pefo@openbsd.org">Per Fogelström</a> and

1.37 miod 66: The early history of this port is not very clear. Apparently the first work was
67: done by CMU as part of their Mach project. The initial hardware was the DEC
68: R2000/R3000-based DECstations. This code was later used by both the Sprite and
69: BSD groups. The 4.4BSD code, known as the <i><a href="pmax.html">pmax</a></i>
70: port, was made freely available in mid 1993. It was merged into the
71: NetBSD tree by a variety of people, but took several years to really become
72: stable and mature, mainly because of compiler toolchain problems.

1.9 niklas 76: Per Fogelström became familiar with the code after porting it to a
1.37 miod 77: home-built IDT R3081 based board. Subsequently he added R4400 support
78: when porting it to the MIPS R4400 Acer PICA board. Willowglen
1.1 deraadt 79: Singapore purchased a second PICA board for Theo de Raadt so that he
80: could improve the port for use as a development system for an internal
1.37 miod 81: project. Since then Theo, Per and others have completed the port.

84: <p>
1.37 miod 85: As a result, the code has been modified to make it more versatile, and
86: eventually support a larger range of ARC machines. Unfortunately the death
87: of this platform, as well as the lack of general availability of this hardware,
88: eventually turned people away from working on this port. Eventually, it was
89: decided to stop supporting it and remove the code from the tree.
