The Little Man Computer simulates machine code programming using a simple instruction set and 100 memory addresses (labelled 00 to 99). This implementation was created to teach students in year 9 studying OCR Computing GCSE. As you can see, it is quite visual and most students found it straightforward to use.

The simulation uses a macro-enabled worksheet created in Microsoft Excel 2007. If you want to run the simulation, you must enable macros after you open the worksheet.
Thanks for uploading this it works really well and I can use it for my ict project!!!!
This excel file is very useful in my teaching. I would like to show some more registers to my students, such as MDR, MAR, … How could I do so?
The simulation is programmed using VBA code. This would need to be edited to provide the additional functionality.
May I have the password to edit the VBA code?
Any chance you will release an unsecured version? Would like to make a modified version with indirect addressing.
I like the tool, tried it successfully with my 9 years old son :-)
However, please could you ad a “run” button that executes automatically until HLT?
I’m glad to hear that it is helping future computer scientists!
My implementation of the LMC runs step-by-step as I wanted my students to follow execution. However, I might consider your suggestion if I find time to review the code.

Thanks for this excellent tool Brian. Please consider sharing it on the CAS website – lots of people would be glad of it.
