The BASIC also supported on-screen editing and direct execution of BASIC instructions. the machine came with 32K of RAM, and had 30,716 bytes free for a Basic program. User memory could be expanded to 40K. JR-BASIC itself occupied 16K of ROM, while the character set video memory and I/O used another 6K. The JR-200 ROM also contained a
