Want to learn more about the ELF and other 1802-based micros? I've found a few places you might enjoy visiting. If you happen to come across a site that might fit in here, please email me the URL and I'll have a look. Thanks!

  • ELF-Emulation.com

    Mike Riley's site with a focus on ELF emulation. If you're looking for an emulator or assembler that runs on Linux, Unix, or Windows, take a look at Mike's site. His emulator can take on the personality of a homebrew ELF, a Netronics ELF II, a Quest Super ELF, a Studio II, and more. Mike is also the author of the Elf/OS as found on the Elf 2000, and this site provides documentation.

  • Docs for 1802 "Membership Card"

    Herb Johnson has created a substantial body of documentation around Lee Hart's tiny Membership Card system that fits in an Altoids tin. From assembly tips to test programs and using the parallel port, this site covers it all.

  • COSMAC Elf 2000 Kit

    Spare Time Gizmos makes building a modern ELF easy. Okay, so the data is input with toggle switches; that's part of the charm, and you wouldn't want to miss out on that. But this board also allows for I/O and memory expansion, battery-backed RAM, program loading from a PC, and more. Nice.

  • Elf 2000 Wiki

    The Elf 2000 manual is amazing and answers everything you need to know to build or operate the Spare Time Gizmos kit. This wiki is a great supplement if you're trying to find vendors for rare parts, and can grow to become a good resource for the community if you take the time to participate. Share your knowledge; it's fun!

  • Propeller-Based ELF II Project

    The Parallax Propeller is a versatile chip, and this Big Brain project will use it to breathe life into a Netronics ELF II simulator. Sentience may follow soon after. Be sure to scroll down the page and check out the other linked resources, too.

  • COSMAC VIP II

    RCA designed, but never released, a successor to the COSMAC VIP. Decades later Ed Keefe has resurrected the project on his own workbench, and has also created a surface-mount version of the VIP. Follow along as he details the process, and check his gallery of nearly 300 photos.

  • The COSMAC ELF Squidoo Page

    Of course there's a Squidoo lens for the COSMAC ELF! Squidoo would be a bit pointless without one, right? Seriously, this popular website may introduce this little computer to a large number of web surfers. Drop by and leave nice comments.

  • Emma 02 Emulator

    Built upon a core by Mike Riley, Marcel van Tongeren's Emma 02 has been grown to emulate a wide variety of CDP1802-based systems, and is now available for several operating systems.

  • ELF in Javascript

    You can run an original ELF right in your web browser with this brilliant piece of work by Maciej Szyc, featuring photo-real graphics. It's the next best thing to firing up your soldering iron and building your own. William Donnelly's enhanced version of this emulator can be found here.

  • TinyELF for OS X

    OS X users can emulate a Netronics ELF II with TinyELF, a free, native Cocoa program that takes advantage of the Mac's GUI goodness. New to the 1802? Tom Pittman's Short Course is embedded in the help system. FYI, cosmacelf.com is run by the guy who wrote TinyELF, so this is a shameless plug...

  • Robert Courtenay's ELF

    Like so many others in the discussion group, Robert's first computer had an 1802 for a brain. According to Robert, who was a big Lost in Space fan back in 1979, a gadget of Will Robinson's inspired him.

  • Paul Robson's RCA Studio 2 Site

    RCA used the 1802 to power their classic Studio 2 game console back in 1976. Paul's site is very thorough, and includes dumps of the cartridge ROMs, a nice CHIP-8 reference, and some emulators.

  • Kustaa Nyholm's Spare Time Labs

    A pumped-up Finnish cousin of the ELF, the Telmac, gave Kustaa Nyholm a start in computing. Check out Down Memory Lane in his site's navigation bar for more on the Telmac and why in an alternate universe Kusti might have been in the position of Bill Gates or Steve Jobs. Be sure to check out his CHIP-8 page, too, for a Nokia phone version and one that'll run right in your web browser. Java is nifty!

  • Ken's 1802 World

    Ken Rother put together a nice site detailing some of his 1802-based projects. Besides the usual ELF-like computer, Ken assembled a music box, a telephone dialer, an add-on for the Commodore 64, and a really tricked-out homebrew micro.

  • Dan Veeneman's COSMAC Page

    Dan has an interest in collecting and preserving all things 1802. Here he shares information and photos of the RCA Microtutor II, RCA's VIP, the Quest Super Elf, and a handheld gadget from Infocel (if you have more information on this unit, please send it Dan's way!). If you're wondering what those suffixes on the 1802 part number were all about, this page has a nice summary.

  • The Antique Chip Collector's Page

    Antique? Who are you calling an antique? Oh... Well, I guess the 1802 has been around a few years, and people collect all sorts of crazy things.

  • COMX 35 Information

    There's little information on the web about the COMX 35, but this page will give you a peek at this machine. One of the comments suggests that the machine had a 75% failure rate! Yikes! Don't blame the 1802, though, they can run for decades even in deep space.

  • Jim Kearney's ELF

    Jim's page features one of the best photos of a classic ELF you'll find on the web, and a second photo showing off its wirewrap construction. Jim says it ran on the first try.

  • Quest Super Elf Manual

    Looking for the Quest Super ELF manual? You've found it!

  • Herman Rober's 1806 Info and Disassembler

    Good information here on the 1805/1806 microprocessors, which are a superset of the 1802. Herman also has C source and a Win32 build of a disassembler, and links to a UNIX-based, hobby-quality 1805 assembler.

  • Sandy Robson's 1802 Handheld

    Eat your heart out, Palm; take a number, Windows CE. Sandy Robson was building a handheld computer back in 1980, complete with a QWERTY keyboard and LCD display. 1802-based, naturally. The project is well documented on Sandy's website. We like!

  • Ted Rossin's Computers

    Ted Rossin built a few 1802-based projects, including a logic analyzer that won an Ohio State University design contest back in 1985. From one of the pictures, it looks like he had a machine running an 1861-based menu. A Pixie GUI?

  • Mark Bitting's 1802 Page

    Mark has recently placed his code for an 1802-based Morse code transmitter identifier on the web, and plans to put up the schematics for the device as well.

  • Tom Pittman's Home Page

    Tom Pittman contributed a great deal to the modest popularity enjoyed by 1802-based computers. Tom wrote Tiny BASIC for the 1802, wrote the ELF II tutorial "A Short Course In Programming", and edited the newsletter put out by Netronics, amongst other things.

  • Bill Richman's Site

    This one you've got to see. Together with Chris Radek, Bill created a beautiful ELF emulator for Windows with a ray-traced user interface. There is a small bug in that the 1802's STXD instruction doesn't decrement, but it's still fun to play with. Bill also has the original Popular Electronics articles online, complete with schematics... if you can find an 1802 somewhere you can still enjoy building one of these simple computers!

  • Article from 1978 Electronic Experimenter's Handbook

    This article by Martin Meyer seems as though it may have been the basis for the Netronics ELF II and possibly the Quest Electronics ELF as well, though I don't know that for certain. In any case, it outlines the ELF II fairly well.

  • Aaron's Virtual Computer Museum

    This is the best resource I've seen on the web for pictures and documentation of the RCA VIP 3300 series terminals, 1802-based TVTs that featured a membrane ASCII keyboard. The site also has a few high-res pictures of a Netronics ELF II worth checking out.

  • Jeff Duntemann Built an ELF!

    I like Jeff Duntemann. Years ago, I read an editorial he wrote (in PC Techniques, I think) suggesting that a good life might be had by living simply and marrying your best friend. He was right; it worked for me! This author, editor, ham radio enthusiast and programmer also built an ELF, as it turns out. Look in the bibliography on his website and you'll see he also wrote several articles on the ELF.

  • The Computer Museum of America

    Call it modern art. There's not much for information, and the museum itself is now closed, but there is a nice picture of a Netronics ELF II with the optional cabinet and some expansion cards. The caption ("RCA COSMAC ELF") is somewhat misleading; some of the chips were manufactured by RCA, but that's definitely a Netronics machine.

  • Yet Another Computer Museum

    Not a lot here, but the site has the best picture of a Comx 35 I was able to find on the web.

  • Vintage Computer Festival

    While this site doesn't offer much specific to the ELF or its cousins, this is an outfit that ELF enthusiasts may very well be interested in.

  • Classic Computer Mailing List

    Questions about the ELF or its relatives? Odds are good that someone on this large, very active mailing list can answer you! Collectors of all types of mini- and microcomputer equipment gather here.
