Irrelevant Pedantry time!
I notice that the computer in your Stuttershock photograph is an Atari XE which- despite the ST-style case- is essentially a repackaged Atari 800, and doesn't support the newfangled 3.5" floppies seen in the photograph (only the older 5.25"). (#)
Also, the 80-column display- which can be seen more clearly in a higher-res version elsewhere- wasn't supported by the XE. (Unless you bought the XEP-80 addon that rather tackily connected via the joystick port (FFS!) and isn't seen here).
Nor does the XE feature either the "alt" or numbered function keys referred to on-screen.
In short, I'm shocked, *shocked*, that the people responsible for creating a stock photo no-one was going to pay much attention to may have faked it. Also, the computer wouldn't have looked that old and yellow when it was still quite new and in genuine use. Etc etc etc...
(#) Even 720 KB DSDD 3.5" floppies would have been impressive at that time. In fact, having a floppy drive at all- mine had a 120 KB 5.25"- beat the living heck out of loading from cassette. Then again, pretty much anything beat the living heck out of loading from cassette.
