The COSMAC 1802 was created in the 1970's at the dawn. Cover Card, CDP1802 microprocessor, 32K RAM, manual, and Altoids tin. Tiny BASIC User Manual by Tom. Note:the CDP1802 COSMAC microprocessor chip is available from any RCA parts distributor as is the COSMAC user manual. The memory contains both instructions and data bytes. Instruction bytes tell the computer what to do with the data bytes. The CDP1802 Microprocessor Kit is a new design single board educational computer. The kit is based on CDP1802 8-bit CMOS microprocessor. System memory are 28kB monitor ROM, 32kB user RAM and 4kB memory mapped I/O. The kit provides HEX keypad and 6- digit seven segment display.

History of the COSMAC 1802, ELF, and the 'Membership Card' A breadboard of the Membership Card circuits. Ode to Eight Bits, by Lee Hart. RCA research (later called Sarnoff Labs) developed the CMOS product line in the early 1970's, including the COSMAC 1802 CMOS microprocessor and other support chips, including software and development hardware. RCA CDP1802 – as 2013 version. Probably the first 8Bit CMOS Processor, introduced about 1976. But how would a time warp of 37 years from 1976 to 2013 affect performance? Hardware description languages like VHDL and Verilog can describe functionality for hardware for implementation into FPGA and ASIC. The RCA CDP1802 (aka RCA COSMAC) is an 8-bit low power microprocessor introduced by RCA around mid 1970's. It was used by many popular early computers (like all the COSMAC ELF variants & VIP in the USA and Telmac in Finland) and has also gone to space controlling satellites (military version is highly resistant to radiation and ESD).

Virtual COSMAC FLEA Simu-Emulator Subscription

Our most popular item is our Virtual COSMAC FLEA Simu-Emulator Subscription. It was our first product offering and how this all got started. It is perfect for people who want to try out our COSMAC FLEA without purchasing the Micro-Trainer (below). It works in all modern web browsers, and on computers, tablets, and telephones. The interface is designed like the original COSMAC ELF as published in the 1975 Popular Electronics magazine article.

For all intents and purposes, it works just like the Micro-Trainer system. And its extended features, like debugging, single-step execution, memory and register display, program loading & saving, and disassembly make it a nice companion piece even if you do buy the hardware version. It makes learning easier and faster. NOTE: Pixie graphics output support is coming soon.

This option is particularly useful for students at educational institutions and classroom instruction. As our most popular item, we have sold over 1,000 subscriptions to individuals in over two dozen countries, and school systems spread across over 500 schools in 7 countries, from secondary through high school, and college and university computer science programs.

COSMAC FLEA Micro-Trainer

Although our Simu-Emulator above is very popular, our COSMAC FLEA Micro-Trainer is the flagship product of our line. (we affectionately call it 'Blue Boy') There is something special about holding a computer that sits in your hand (or pocket) and being able to program it and work with it. It is basically based on the original COSMAC ELF, but condensed so it fits in a G'day Mints tin. Thereby our 'A ELF for Everyone!' motto. An Instruction Manual contains user information and building information for the kit form, as well as a parts list, schematics and other info. See below for books, booklets, and other manuals. And software.

The COSMAC FLEA comes pre-built (by professional, qualified technicians), or as a kit for those more adventurous. But building it is pretty simple and easy, so don't be daunted. The kit contains all of the parts you need. Both versions include a tin filled with candy mints. All you have to do is supply a soldering iron for the kit and drill some holes and cut some openings in the tin.

We also have a front panel board option to make it look nicer. And check out our expansion modules below. And if you want to roll-your-own, we have bare boards.

COSMAC FLEA Hex Keyboard & Display

One of our latest products is starting to sell well. Our Hex Keyboard and Hex Display module also fits in a tin. The 20-key keypad makes entering programs much easier. It can also be used for FLEA-8 games (see below). An additional unit can also be interfaced for two-player games. There are six .3' hex displays to show the 8-bit data bus and 16-bit address bus. Once you have learned the basics, and entered some programs using the toggle switches, you will quickly want to upgrade to a hex keyboard, and seeing the data bus and address in hex is very convenient, as well.

COSMAC FLEA 1861 Pixie Replacement

The CDP1861 Pixie display chip is rarer than hens' teeth and is almost impossible to find. (it is rumored to be composed of rare Unobtainium) But that is a problem no longer with the COSMAC FLEA 1861 Pixie Replacement module. It is plug-compatible and performs the same functions.

We also have a COSMAC FLEA extension module that contains the Pixie Replacement and a sound module with a speaker, amplifier, and volume control that connects to the Q output of the COSMAC FLEA. This can be used to play music and tones. This module also fits in its own tin. With this extension, you can play FLEA-8 games and use it for output for CF Tiny Basic and other software programs.
