About NetBSD/sun2

NetBSD/sun2 is the port of NetBSD to the Sun Microsystems sun2 series of computers, which are based on the Motorola 68010 CPU with a Sun-designed custom MMU. Sun sold these computers as both servers and desktop workstations from the early to mid 1980's. They were superseded by the sun3 systems, which are supported by NetBSD as NetBSD/sun3.
