Emulatron X-ray

Watch registers and memory inside seven machines. Pause the scan, then step through a diagnostic frame.

What am I looking at?

Real WASM cores, real state snapshots, no server round-trip. This page boots a tiny MOS 6502 loop, a C64/VIC-II-ish clean-room PRG fixture, a Z80 scratchpad loop, an Intel 8008 I/O loop, an Intel 8088 clean-room COM-style fixture, the deployed Calculator-8008 ROM bridge, and a TI CC-40 BASIC sequence, then renders registers, memory windows, video state, observed SID-window writes, I/O latches, calculator display/key bridge state, serial and printer output, LCD state, and cycle counters live in the browser. Green-highlighted fields changed since the previous sampled snapshot; this is not a full bus trace.

  • MOS 6502 + VIC-II state
  • C64 clean-room PRG sample
  • Z80 registers + scratch RAM
  • Intel 8008 registers + OUT ports
  • Intel 8088 clean-room COM fixture
  • Calculator-8008 ROM bridge
  • TI CC-40 LCD + CGRAM
  • Pause, step and compare
Live: refreshing every 140 ms from local WASM state.
