General Information
The Cosmac Elf was first published in August 1976 as a DIY kit in the 'Popular Electronics' magazine. Different extensions were published afterwards like a hex keypad and a graphics chip (CDP 1861). Because a lot of different extensions were designed over the years the emulation of the Cosmac Elf (as well as the Netronics Elf II and Quest Super Elf) emulation have been kept very flexible.
