Sierra Systems (shall not be confused with the Canadian IT services and consulting firm Sierra Systems Group Inc.[2][3]), is a company founded in 1980 in Oakland, California by Electrical Engineer, Inventor and Video Games Industry pionner Larry Rosenthal[4][5] (Lawrence David Rosenthal).
Larry was a 17 years old student[6] at the Massachusetts Institute of Technology (MIT), when he saw in 1962, for the first time Spacewar! running on a PDP-1 Computer. Impressed with what he saw Larry created in 1973 his own processor and computer[7] built with surplus parts obtained from a run-down store near the Oakland airport called Mike Quinn Electronics[8] thus creating his home version of Spacewar!. He called his invention the Vectorbeam System[9], which turned to be the first coin-op video game to make use of a vector display.
He licensed[6] his new invention to Cinematronics, a pioneering arcade game developer, based in El Cajon, California that had its heyday in the era of vector display games, who released it in 1977[6] as Space Wars[10]. Discontent with the royalties received Larry quit Cinematronics taking with him the "Vectorbeam System"[11] in the Spring of 1978 to form his own company called Vectorbeam[10][12][13] (named after his creation) but after facing huge financial problems and being pressed to sell the Patents of his invention by Cinematronics Larry finally gave up and sold[14] the company with the patents back to them in 1979.
After exiting the video game field, Larry founded Sierra Systems in 1980, producing[15] embedded systems development tools, one of them, the Sierra 68000 C Compiler, was largely used in the early 90's in 68000-based applications ranging from navigational systems to printer applications and video games.
Currently, Larry Rosenthal trades as KeyRinger, LLC.[16][17][18], focusing in the sale of one of his last inventions, a lost key finder and remote control locator called KeyRinger XL™ (an improved version of the original KeyRinger™[19][20]).
