Original IBMPC came with BASIC in ROM, just like a TRS-80, a Commodore
PET, a Coleco ADAM, or an Apple ][. If you didn't boot from a
bootable floppy, instead of giving you a diagnostic about a missing
operating system, they came up with an interactive BASIC.
So what happens if you use any of those interrupts that are reserved
for BASIC? Well I'd guess that you might have a problem running them
on any original IBMPCs that are more than fifteen years old.
This won't affect clones.
