	Well, we have a 'Hardware available/wanted' page:

	Could I encourage people to submit items for addition to
	the page, both available and wanted - offering to help someone
	interested in working on a port would definitely be worth an
	entry :)

	Dave/Scott - would you be willing to list your hardware?

	Toru Nishimura ( was looking for a
	64bit capable pmax box to work on NetBSD/mips64 - maybe he might
	be interested in a r4400 or better SGI instead? Toru? :)

	IRIX used to use E?COFF, but now uses ELF.


                      Neighbours should be one of:
                a) Understanding   b) Distant   c) Deaf
