https://peertube.scd31.com/videos/watch/7d3bbc67-b050-44a4-9006-e2d7dfe2f653 Messing around with my M68K SBC today. Has lots of bugs and I haven't touched it in a few years. Here I have it running in single-step mode with the steps coming from a signal generator. The speed varies throughout the video but it stays between 10Hz and 1000Hz or so. This program just writes some ASCII art to the serial port, but it also generates some pretty blinkenlights! The left lights show the value on the data bus and the right lights show the value on the address bus.
