CPU Computer Simulators vs RTMsim
Both stand on physics simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan MacWindows
CPU Computer Simulators offers a broad, free simulation library organized around an instructional cycle. Its age and lack of support create compatibility considerations for current computers.
