6502 Simulator
A 6502 microcomputer with a VIC video chip and a real 6522 VIA timer — runs in your terminal and in your browser, same code.
A working 6502 microcomputer simulator on a path toward a teaching tool. CPU, RAM, ROM, VIC video chip, and a 6522 VIA peripheral wired to a memory-mapped bus with hardware-realistic chip-select decoding — demos written here are intended to transfer to real silicon unmodified. Built in Go on top of foxpro-go (a from-scratch homage to FoxPro for DOS) and 6502-netsim-go (a transistor-level Visual6502 port). Same source compiles as a TUI and as a WebAssembly app.
