Emulatron X-ray

Watch registers and memory across seven demos. Pause the live scan, then advance one sample.

What am I looking at?

Choose a demo to inspect its registers, memory, display and I/O values. MOS 6502, Z80 and Intel 8008 loops sit alongside a C64 display demo, an Intel 8088 I/O demo, the Calculator-8008 ROM and a TI CC-40 BASIC sequence. Everything runs in this browser. The C64 program runs once and halts; its card then resamples cached state. Green-highlighted fields changed since the previous sampled snapshot; this is not a full bus trace.

  • MOS 6502 + VIC-II state
  • C64 display demo
  • Z80 registers + scratch RAM
  • Intel 8008 registers + OUT ports
  • Intel 8088 I/O demo
  • Calculator-8008 display and keys
  • TI CC-40 LCD + CGRAM
  • Pause, step and compare
