The '''COSMAC Elf''' was an [[RCA 1802]] microprocessor-based computer described in 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, enhanced kits that were based on this design. The system was a very early single-board [[personal computer]]. It was operated without built-in [[Read-only memory|ROM]]s and programs were entered directly with help of the [[CPU]] integrated [[Direct memory access|DMA]] using 8 [[toggle switch]]es and an Input push button. An updated version was later sold in kit form, the [[COSMAC VIP]].
