Editing COSMAC ELF (section)

== Software ==
A series of newsletters and small booklets offered by Netronics and Quest contained 1802 machine language and [[CHIP-8]] programs, along with schematics for expanding the Elf and adding peripherals, including a light pen. Other, similar information and hobbyist software projects can be found on the Internet. The only published book about the 1802 is Tom Swan's "Programmer’s Guide to the 1802" (1981), which has been made available as a [[PDF]] after being out of print for many years.<ref>{{Cite web|url=http://www.tomswan.com/|title=Programmer’s Guide to the 1802|last=Swan|first=Tom|date=1981|website=Tom Swan Homepage|publisher=Tom Swan|access-date=19 August 2016}}</ref>

Tiny BASIC, a version of [[BASIC]] offered by Tom Pittman, could be used to write small BASIC programs on the Elf that could display through the Pixie low-resolution monochrome graphics display or TV-Typewriter hardware. Pittman also wrote a small booklet about the 1802 titled "A Short Course In Programming", which he has allowed to be published and made available online free of charge.<ref>{{Cite web|url=http://www.cosmacelf.com/publications/books/short-course-in-programming.html|title=A Short Course In Programming|last=Pittman|first=Tom|date=1980|website=COSMAC Elf|publisher=Dave Ruske|access-date=19 August 2016}}</ref><ref>{{Cite web|url=http://www.ittybittycomputers.com/IttyBitty/ShortCor.htm|title=A Short Course In Programming|last=Pittman|first=Tom|date=1980|website=Itty Bitty Computers|publisher=Tom Pittman|access-date=19 August 2016}}</ref>

Mike Riley has written an editor, assembler, [[BASIC]] and [[FORTH]] interpreters, a [[BIOS]], and the Elf/OS [[disk operating system]] that will run on expanded Elf systems, including the COSMAC Elf 2000.

Other languages available are noted at the [[RCA 1802]] Wikipedia entry, including [[Interpreter (computing)|interpreters]], [[compiler]]s and [[Assembly_language#Assembler|assemblers]].

Game cartridges for the RCA Studio II contain Chip-8 games, which can run on other 1802 systems. File dumps of these games can be found on the Internet.
