RCA CDP1802 COSMAC microprocessor data, books, newsletters, history, and photos of computers and devices based on this pioneering 8-bit CMOS chip. My first computer was a Netronics Elf II. To enter data, select Load mode In 1976, Popular Electronics published plans for a computer called the COSMAC Elf which you could build for under $100, and much less if you had a good junk box. Identified connections on the left go to the "front panel" with the eight data switches. The remaining can be left Way back in the days when most microcomputers were beyond the means of all but the most dedicated hobbyists, Popular Electronics published in its August 1976 Way back in the days when most microcomputers were beyond the means of all but the most dedicated hobbyists, Popular Electronics published in its August 1976 issue an article entitled 'Build the RCA CDP1802 COSMAC microprocessor data, books, newsletters, history, and photos of computers and devices based on this pioneering 8-bit CMOS chip. Complete circuit for the Elf computer. The CPU is simple enough to program directly in machine Building and programming an ELF is about as basic as it gets when it comes to learning the rudiments of micro-computing. Back in 1976, I saw the Popular Electronics magazine article for building the very inexpensive COSMAC ELF microcomputer project, and wanted to make one but somehow never did. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects. Join this group to discuss these ********UPDATE August 2017:I used the spare parts from this ELF build to make a another, duplicate, ELF computer, differing only in that the second one does The Membership Card is a modern version of the 1976 Cosmac Elf. A blast from the past. For many of us, it was the RCA 1802 thanks to the COSMAC Elf articles that ran in Popular Electronics. All scans in this repository are provided for The COSMAC history Cosmac ELF project has been imagined and thought a lot of time before its publication, and it is consequence of Joseph Weisbecker's (creator of the ELF itself) work involved in After creating a beautiful replica of the original COSMAC ELF, Paul Schmidt documented the heck out of it and made his hard work available for others to Posted in Arduino Hacks, classic hacks, computer hacks, Hackaday Columns Tagged 1802, arduino, cosmac, cosmac elf, emulation, kim, kim-1, KIM1, RCA 1802, rca cosmac, retrocomputer The heart of the Elf microcomputer is the new RCA CDP1802 COSMAC microprocessor chip that sells for less than $30. 9. Everyone remembers their first. This article provides a detailed schematic of the Cosmac Elf, Contrast the ELF with the various “Arduino” and “Raspberry Pi” microcomputer platforms that offer hobbyists powerful ways of implementing microcomputer A Cosmac Squeeze: This remake of the 1976 Cosmac Elf uses the same CDP1802 processor [top] and a stripped-down version of the front panel found on early micros [second photo from top].

This program use a COSMAC Elf microcomputer (CDP1802 microprocessor) with a PIXIE graphics chip (CDP1861) to display a digital clock on an NTSC monitor. However, it is a fun retrocomputing toy, inexpensive, and a great learning tool. We ️ Forth! “COSMAC ELF Microcomputer Trainer User’s Manual” and build documentation by Paul Schmidt When Popular Electronics detailed the original COSMAC ELF in 1976, the article was COSMAC ELF Group cosmacelf@groups. io The RCA CDP1802 COSMAC microprocessor was the basis for several hobbyist computers in the mid 70s and early 80s. Programming Welcome to the COSMAC ELF group Wiki, a public resource edited and maintained by enthusiasts of computing equipment powered by the CDP1802 microprocessor and its close relatives. They are based on the RCA COSMAC 1802 processor and the early ELF microcomputers with that CPU. Their first CPU, that is. "For those just tuning in, the Membership Card The COSMAC Elf is a fully operational 8 bit computer you can build at home with only a few tools. I built mine from a kit, but Popular Electronics Magazine had an article on how to build one from scratch. A subreddit to discuss and share retrocomputing related content. The Plan 2016 was the 40th anniversary of the ELF. It was an RCA 1802 based single board computer that was sold as a kit, but it had a The Cosmac ELF was one of the more interesting specimens from this era, and this one has been meticulously reproduced on an FPGA. Parts cost is about $10. It works (at least externally) like a regular ELF. What may be more surprising is that the Enhanced kits such as the Netronics Elf II and Quest Super Elf added built-in features such as keypads for data entry, serial I/O, cassette interface, and the Contribute to petersieg/cosmac-elf development by creating an account on GitHub. His new RCA 1802 computer has bank switching, allowing the plucky little processor to address 256K of RAM. 4. However, you do need Nominally, you can operate the entire device via the built-in keypad and display. You can see the arduino hiding in the hideous mess of wiring below. I wonder if it's possible to emulate 70's and 80's microcomputers, such as the TI-58/59, or COSMAC ELF with Arduino? I want to learn assembly language! I'm aware of the emulators for PC and mobile I am going to build at least one ELF that is in the spirit of the original ELF from 1976.
