An interesting observation. It prompts the thought of how far away this simulator is from an actual ZX81, and how much it has been pulled away from a ZX81 by dint of training data where simulated retrocomputers of other types all boot into copyright messages. I wonder how often the spicy autocomplete engine tried to make it put up a "READY" or "OK" prompt.

One ZX81 clone actually did have a "READY" prompt, I read. Actual intelligence was doing the same in the 1980s. (-:
