> with the first machine, the SPARCstation1 (a.k.a. Sun 4/60, a.k.a Campus), being delivered in 1987. Quoting WiKipedia: 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 processors of previous Sun models. These all proceeded the 4/60 aka SPARCstation (1), which wasn’t introduced until April 1989.
