My guess is that clones used the same method. They

basic, INT 18h points to a little bit of code that displays the No ROM
BASIC message (as far as I can see this message is not in the IBM ROMs)
and then halts the CPU.
This was the point to my original question: why would clone makers go to
the trouble of displaying the message and then halting the system, instead
of just *halting the system*? (Unless they were using stolen code.) Just
doesn't quite make sense . . .
