[school-discuss] Johnny -- A Simulator of von-Neumann Computer Architecture for Educational Purposes (Open Source)

[Peter Dauscher <dauscher@xxxxxxxxxxxxxxxxx>]

Dear SchoolForge Users,

I would like to announce a simulation software that can be used in
computer science classes:

JOHNNY
is a simulator of a simple (virtual) von-Neumann Computer. Its principal 
application is education; therefore a number of simplifications are 
made: rather reduced instruction sets, simplified bus operations, etc.

It visualizes the function of Memory, Arithmetic Logic Unit and Control 
Unit. Machine Programs can be created and edited using a comfortable GUI 
and run on the virtual machine step by step. The von Neumann instruction 
cycle is shown in a rather instructive way.

Micro Code, too, is editable: Instructions can be added and modified 
using the GUI.



The Microsoft Windows executable as well as the (Free Pascal / Lazarus) 
source code (usable for Linux, MacOS etc.) can be obtained here:

http://sourceforge.net/projects/johnnysimulator/


It's also documented on the SchoolForge pages:
https://schoolforge.net/education-software-download/johnny


If you have questions, remarks, bug reports or suggestions concerning 
the software itself or the users' manual (including orthography, wording 
and grammar -- I am not a native English speaker), please let me know.

Thank you very much in advance
- Peter Dauscher
