1977 MS 6502 BASIC ROM in the browser

Microsoft just open sourced their 1977 BASIC interpreter that's used in the Apple ][ and Commodore 64 8 bit PCs from the 70s and 80s. I've built the 6502 Assembly Language they open sourced into a 6502 binary and and am creating a solution to run it directly within a browser. I'll be providing 2 user experiences: Apple ][ & Commodore 64.
