#+TITLE:  Flora Computer Simulator

#+DATE:   2015 Nov 06

One day, my daughter read a book, [[http://www.mhpbooks.com/books/adas-algorithm/][Ada’s Algorithm]], for her English

class, and we had lots of discussions about Ada’s actual contributions

to the field of computer science.

He work described the concept of an algorithm, which was the first

computer “code”, but to render her ideas, I decided that I might

create a /simulator/. Since I’m not knowledgeable on Babbage’s

original engines, I thought the simulator could resemble the 6502

processor that I fell in love with as a boy.

This simulator is a complete web application and requires no

server-side code or framework. It is written CoffeeScript, and the [[file:ada.coffee][CPU

instructions]] should be simple enough to understand (the parser code in

the [[file:hardware.coffee][hardware.coffee]] file makes heavy use of [[https://lodash.com/][LoDash]]’s =reduce=

function, and may be more difficult to follow).

Its use, however, is a very simple, controlled “central processing

unit” that could be used to teach students the underlying technology

of all computer systems... The teaching part is what I’m currently

working on.

  If you would like to host this project, clone this repository to

  some directory available on your web server. Some files are not part

  of this repository, and should be easily downloaded:

  - [[https://raw.githubusercontent.com/lodash/lodash-compat/3.10.1/lodash.min.js][LoDash]] :: =js/lodash.js=

  - [[https://github.com/js-cookie/js-cookie][JS-Cookie]] :: =js/js.cookie.js=

  - [[https://jqueryui.com/resources/download/jquery-ui-1.11.4.zip][jQuery UI]] :: =ui/jquery-ui.js=

  - [[http://www.kreativekorp.com/swdownload/fonts/retro/pr.zip][Apple's Bitmapped Font]]  :: =PrintChar21.ttf= (see [[http://www.kreativekorp.com/software/fonts/apple2.shtml][this page]])

  - [[http://www.fonts101.com/fonts/view/Uncategorized/51303/Motter_Tektura][Motter Tektura Font]] :: =fonts/mottertektura.tff=

  That should do ’er.
