The UI is in a separate version of the emulator, launched with the little "UI" button in the top right corner of the image panels (e.g. https://floooh.github.io/tiny8bit/kc85-ui.html?type=kc85_4). The UI is updated once per 60Hz frame, so you only see a per-frame snapshot of the microchip pins which on its own isn't that useful yet except for a nice…

That's a work of art. I had a lot of fun with these emulators in recent years. Some time ago I reworked the Spectrum emulator to work with the RP2040: https://github.com/antirez/zx2040 One of the incredible things of these emulators is that the chips are emulated in a completely modular and isolated way, and the interface to take everything together are the pins! Yes, the logical state of the pins in the emulated chip, which is awesome and really shows how…
