Unironically, yes, this, Ifsuѧl Bacti1on|, and weird computer shape (extra-thick 3.5"-looking floppy and... what that slot is even supposed to be?) makes it look worse than it should. I get that the value is in other content, and this is just a basic illustration for the sake of having some picture (for aesthetics, I guess?). So it was made with minimum effort possible just to have something, that's cool, effort matters elsewhere.

But it doesn't only look sloppy or hastily made, it also looks inaccurate - and that really makes a bad impression. "Inaccurate" or "careless" are not the words any author should want their reader to think about.

A screenshot from an emulator, showing the same message but formatted as a BASIC program (just a bunch of PRINTs or REMs) - or something similarly simple to make, lacking glaring inauthenticity - would make a drastically better impression.
