It was developed by Jeffery Goldberg, MS. who left <a href="/facts/Bell_Labs/fKP5Gk0H">Bell Labs</a> after using <a href="/facts/Unix/0pNL2seI">Unix</a> and became VP of engineering for Charles River Data Systems (CRDS), now defunct. UNOS was written to capitalize on the first 32-bit microprocessor, the <a href="/facts/Motorola/ztqczx68">Motorola</a> <a href="/facts/Motorola_68000_series/jxd7VPlW">68k</a> <a href="/facts/Central_processing_unit/Jxp1bqMV">central processing unit</a> (CPU). CRDS sold a UNOS based 68K system, and sold porting services and licenses to other manufacturers who had embedded CPUs. </p>
