Days of fire
Who once sold a monochrome CRT monitor that apparently would emit smoke if f the computer used allowed higher resolutions to be set than the monitor power supply could support.
Whose 5MB HDD [for the Tandy 2000] acted similarly (unless modified*) because the stopped/stalled motor surge current was too high for the windings.
* IIRC, the fix was a series resistor that required a number of those HDD's be twisted back and forth to break stiction and start up.
Good. Quick. Cheap You only get TWO at a time.
