This Vue-based educational tool simulates Troy’s 8-bit breadboard computer, showing the full fetch-decode-execute cycle through an integrated assembler and debugger. The emulator interface renders live register values (Ra, Rb, PC, Acc), processor flags (C, Z, N, O), and memory contents, updating step-by-step as users execute assembly instructions. The code uses the Vue framework to bind UI controls like Run, Step, and Reset to the emulator’s internal clock and ALU operations, while the assembler translates labeled source into binary machine code. Data flows from the assembly source through parsing and address resolution into the simulated CPU state, visualized as a schematic of the physical breadboard layout.
