Commercial Versions
The original ELF computers were essentially home-built versions of the RCA Microtutor I and Microtutor II, which were RCA's demonstration boards for their CDP1801 and CDP1802 microprocessors.
Enhanced kits such as the Netronics Elf II and Quest Super Elf added features such as keypads for data entry, serial I/O, cassette interface, and the CDP1861 "Pixie" video chip. RCA later introduced their own expanded version as the COSMAC VIP.
In August 2006, Nuts and Volts magazine, along with Spare Time Gizmos released a project to build the "Cosmac Elf 2000," based on the original ELF, with some newer and easier to find components.
