Sun-3

A Sun 3/60 workstation with disk and tape

Sun-3 was the name given to a series of UNIX computer workstations and servers produced by Sun Microsystems, launched on September 9, 1985.[1] The Sun-3 series were 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.[2]

(Max. RAM sizes may be greater when third-party memory board were used).

Sun-3x

A Sun 3/80 workstation

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 used a Motorola 68030 processor, 68882 floating-point unit, and the 68030's integral MMU. This 68030-based architecture was called Sun-3x.

Model Codename CPU board CPU MHz Max. RAM Chassis
3/80 Hydra - 20 MHz 16, 40 or 64 MB "Pizza-box" desktop
3/460 Pegasus Sun 3400 33 MHz 128 MB 12-slot VME (deskside, older design)
3/470 Pegasus Sun 3400 33 MHz 128 MB 12-slot VME (deskside, newer design )
3/480 Pegasus Sun 3400 33 MHz 128 MB 12-slot VME (rackmount)

Sun 3/260s upgraded with Sun 3400 CPU boards were known as Sun 3/460s.
