And we liked the project very much.&lt;p&gt;It has a very small and concise schematics which makes it very easy and clear how CPU really works.&lt;p&gt;P.S.: the original simulator is written in C++&amp;#x2F;CLI (a .net flavour of c++), so I decided to refresh the project (to c#, it was easier to translate than to port to native c++), and added a real 1602-display simulator which looks nicer and support a “graphic” mode.
