Retröhead

Sun Ultra 20 produced in 2007 can't really be described as retro, more like obsolete hardware. Nevertheless as I've never seen a Sun workstation before or used one I grabbed this unit with me for 20 euros at a flea market. Short history lesson: Sun (Standford University Network) was and American company founded in 1982. It produced and contributed on wide range of software and hardware such as SPARC processor architecture, Java programming language, Solaris, UNIX, RISC, virtualized computing and so on. In 2005 Sun released Ultra 20 workstation moving towards x86-64 architecture. In 2008 Sun released it's last SPARC architecture workstations.  In 2009 Oracle acquired Sun and a year after that released it's last workstation ever, concluding it's history as a workstation vendor. On September 2, 2017, Simon Phipps reported that Oracle had laid off the Solaris core development staff. Ultra 20: What's on the outside? Manufacturing quality of Ultra 2
