Thank you for liking my #PERSEUS-9 homemade mobile 6502 computer! A few days ago, I was checking the behavior of a homemade floating point interpreter on this computer when I used multiple characters in a variable. Today, I am printing out my entire PERSEUS articles and binding them together to read them book style.
