In 1975 Systems Resources Corporation merged with Computer Exchange, a used-computer brokerage owned by engineer Leon Weissman, who had also worked for Leonard at Digitronics (Director of Engineering, 1962 -1964). Weissman's company had cash but its business was in a slump. The merger provided Systems Resources Corporation with funding beyond Mechner's contributions. The name of the merged company was soon changed to Chiron and it was located in Plainview, New York only a few miles from the company's present location in Melville.
