Please make sure you have the latest version of the JRE installed. You can use java -version on the command line to see. Make sure it’s 1.9 or 1.10.

You can install the JRE from this link.

I have made changes to both programs to improve usability and fix annoying bugs. Please download and use my versions instead of the ones listed on their respective websites.

MARS - This is the MIPS simulator we’ll be using for the first half of the course.

Logisim - This is the circuit simulator we’ll be using for the second half.

If you run into problems with these programs, PLEASE let me know!
