The
COSMAC ELF was an
RCA 1802 microprocessor-based computer based on a series of construction articles in
Popular Electronics magazine in 1976 and 1977. Through the back pages of electronics magazines, both Netronics and Quest Electronics offered low-priced kits that were based on this design. The system was a very early
personal computer. It was operated without built-in
ROMs and programs were entered directly with help of the
CPU integrated DMA.
