SuperMON is a post market mod. Your computer should have a metal switch. The advantages of SuperMON is when it is turned on, you don't need a Translator disk to run Atari 800/400 software. Also it has a built in Screen Dump feature too (like a print screen), but I can't remember how to activate that. Its been like 30 years. SuperRAM is also another option that may come with the computer which included a 256k ram upgrade.
