Contribution

Ralph Campbell constructed an early Altair (#220218) and humorously placed an "OBSOLETE" sticker on it's front panel. Tiring of toggle switch flips, he wire wrapped his own CPU board with EPROM monitor and video display. Ralph later contributed to the creation of RISC I & II architecture at Berkeley (which led to SUN's SPARC architecture, among others) and went on to become one of the principal developers of Berkeley UNIX (BSD 4.2, 4.3, and 4.4) and BIND (DNS).
