[MinnowBoard] GSoC-2015 WITCH-on-a-Board

[Anders, David]

Greetings All,

For those interested in the Google Summer of Code WITCH-on-a-Board, I'd like to share some background information. The WITCH is considered the older ORIGINAL working computer in the world. It is a fascinating machine in the aspect that is has all the components of a modern system, but implemented with cold cathode tubes and relays. Oh, and there is one more unique item: it is a decimal based computer NOT binary based! An ongoing documentation and educational project based around the WITCH has been created to coordinate efforts. The project is known as WITCH-E (http://www.witch-e.org). last summer we had a young student create a javascript based emulator for the WITCH, however there are some limitations to what can be done in a browser and it does limit the amount of hardware experimentation. In a past project a complete replica of the ENIAC was created in a single chip as a research project(http://www.seas.upenn.edu/~jan/eniacproj.html). In preparation for developing this ENIAC hardware, a solid and complete emulator was created in order to understand the nature of the design. As the WITCH-E project intents to create replica hardware, the first task is to get a similar emulator created for the WITCH. The known (public) documentation for the WITCH is available through the project website.
