1.45 miod 22: OpenBSD/arc used to run on the machines compatible with the <i>Advanced RISC
1.37 miod 23: Computing</i> specification, known as ARC machines, based on MIPS processors
24: and initially designed to run Microsoft Windows NT.
1.45 miod 25: Such machines included the long dead Acer PICA, as well other machines
1.37 miod 26: manufactured by other companies such as MIPS, Deskstation, NEC, and Olivetti.
27: </p>
28:
29: <p>
1.45 miod 30: The ARC specification is extinct, and no new ARC BIOS machines for MIPS are
31: likely to ever be manufactured.
32: Microsoft has stopped supporting MIPS platforms after NT 4.0.
33: OpenBSD/arc used to provide a good alternative to NT!

1.47 ! deraadt 37: <strong>The OpenBSD/arc port was discontinued after the 2.3 release.</strong>

40: <p>
41: There is currently no one working on bringing this port back to life.
42: The source code is still available in the CVS Attic, and code can be found in
43: NetBSD as well.

1.37 miod 61: The early history of this port is not very clear. Apparently the first work was
62: done by CMU as part of their Mach project. The initial hardware was the DEC
63: R2000/R3000-based DECstations. This code was later used by both the Sprite and
64: BSD groups. The 4.4BSD code, known as the <i><a href="pmax.html">pmax</a></i>
65: port, was made freely available in mid 1993. It was merged into the
66: NetBSD tree by a variety of people, but took several years to really become
67: stable and mature, mainly because of compiler toolchain problems.

1.9 niklas 71: Per Fogelström became familiar with the code after porting it to a
1.37 miod 72: home-built IDT R3081 based board. Subsequently he added R4400 support
73: when porting it to the MIPS R4400 Acer PICA board. Willowglen
1.1 deraadt 74: Singapore purchased a second PICA board for Theo de Raadt so that he
75: could improve the port for use as a development system for an internal
1.37 miod 76: project. Since then Theo, Per and others have completed the port.

1.37 miod 80: As a result, the code has been modified to make it more versatile, and
81: eventually support a larger range of ARC machines. Unfortunately the death
82: of this platform, as well as the lack of general availability of this hardware,
83: eventually turned people away from working on this port. Eventually, it was
84: decided to stop supporting it and remove the code from the tree.
