Microprocessors ß-20XX

What's that?

ß-20XX is a family of two custom Microprocessors (ß-2015 and ß-2018), based on the Zilog 80 model, made with logisim. You can reprogram the Control Unit using the ß-RomWriter or create your custom programs using the ß-Assembler.

Details

Open Source
This project is 100% and open source, you can download the Mp, Assembler or RomWriter source code and compile your own version or simply download the procompiled versions.
Made with Logisim
ß2018 is made with Logisim to let you know what happens inside the microprocessor during the execution of all operations.
Z80 Compatible
ß2018 is developed on the Z80 model so it is compatible with the Z80's instructions set and Z80's programs.
