Hello edu-eu,

I found this on a different mailinglist and thought it might be
interesting to someone.

Greetings,

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
