Sun-4
From Computer History Wiki
Sun-4 is a series of Unix workstations and servers produced by Sun Microsystems, launched in 1987. The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68K family CPUs of previous Sun models.
Sun-4 support was included in SunOS3.2 onwards and Solaris 2.1 to 2.4. OpenBSD and NetBSD also will run on the Sun-4 architecture families.
They ranged from speeds of 16.6 Mhz to 33 Mhz.
