HP introduced its low cost 1000 Series processor in 1979, the L-Series. Like the 21-MX computers, the L-Series was driven by the RTE operating system (RTE-L). The L-Series represented a significant departure in hardware design for HP 1000 computers. The L-Series was based on HP's new LSI CMOS/SOS (Silicon on Saphire) processors. This processor had no Dynamic Mapping System (DMS). The CPU included an SOS processor as did each interface board. The processor residing on the interface boards gave those boards full access to computer memory, relieving the main CPU of IO control operations. This design provided the L-Series with much faster performance and throughput than the 21-MX computers. The interface boards for the L-Series were not backward compatible with the 21-MX or early 2000 computers.
