EspañolSUN-3
'Sun-3' was the name given to a series of UNIX computer workstations and servers produced by Sun Microsystems, launched in 1985. 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.
Models are listed in approximately chronological order.
(Max. RAM sizes may be greater when third-party memory board were used).
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'.
Sun 3/260s upgraded with Sun 3400 CPU boards were known as Sun '3/460's.
