Editing COSMAC ELF (section)

== Microcomputers ==
The original Elf computers were essentially home-built versions of the [[RCA]] Microkit, Microtutor I and Microtutor II, which were RCA's demonstration boards for their CDP1801 2-chip predecessor and single-chip CDP1802 microprocessors.

Enhanced kits such as the [[ELF II|Netronics Elf II]] and Quest Super Elf added built-in features such as keypads for data entry, serial I/O, cassette interface, and the CDP1861 "Pixie" [[Video Display Controller|video]] chip.  RCA later introduced their own similarly expanded version as the [[COSMAC VIP]].

In August 2006, [[Nuts and Volts]] magazine, along with [http://www.sparetimegizmos.com/ 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 and enhanced features, modules, and functionality, including the STG1861 Pixie Graphics Replacement board that is functionally equivalent to the now-rare RCA CDP1861 integrated circuit.

The [http://www.retrotechnology.com/memship/memship.html Membership Card] is a modern, simple COSMAC Elf-like remake for [[retrocomputing]] hobbyists that is designed to fit in an [[Altoids]] tin.

Various other hobbyist systems can be found on the Internet, including [[Hardware emulation|hardware emulator]]s using FPGA and modern [[microcontroller]]s.
