Sun-3
Sun-3 is a series of UNIX computer workstations and servers produced by Sun Microsystems, launched on September 9, 1985. The Sun-3 series are VMEbus-based systems similar to some of the earlier Sun-2 series, but using the Motorola 68020 microprocessor, in combination with the Motorola 68881 floating-point co-processor (optional on the Sun 3/50) and a proprietary Sun MMU. Sun-3 systems were supported in SunOS versions 3.0 to 4.1.1_U1 and also have current support in NetBSD and Linux. It used to be supported by OpenBSD but the port was discontinued after the 2.9 release.
Models are listed in approximately chronological order.
(Max. RAM sizes may be greater when third-party memory boards are used.)
The Sun Type 3 keyboard is split into three blocks:
It shipped with Sun-3 systems.
In 1989, coincident with the launch of the SPARCstation 1, Sun launched three new Sun-3 models, the 3/80, 3/470 and 3/480. Unlike previous Sun-3s, these use a Motorola 68030 processor, 68882 floating-point unit, and the 68030's integral MMU. This 68030-based architecture is called Sun-3x.
Sun 3/260s upgraded with Sun 3400 CPU boards are known as Sun 3/460s.
