OpenBSD/arc OSREV runs on the following classes of machines:
	- Acer PICA61 (RISC-PC) Systems.
	- Deskstation rPC44.
	- Deskstation Tyne.

OpenBSD/pmax OSREV does *not* (yet) run on these machines:
	- Mips Magnum
	- Olivetti systems.
	- SNI RMxxx machines.
	- NEC Risc.

The minimal configuration requires 8M of RAM and ~60M of disk space.
To install the entire system requires ~150M of disk space, and to run
X or compile the system, 32Mb of RAM and ~1G of disk is recommended.
