Sun-3

Sun-3 is a series of UNIX computer workstations and servers produced by Sun Microsystems, launched on September 9, 1985.

[1] 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.

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.

Unlike previous Sun-3s, these use a Motorola 68030 processor, 68882 floating-point unit, and the 68030's integral MMU.
