will find that at least one such emulator is itself being emulated.
Don't be too surprised if the legacy app is IBM 360 code running
under an emulator written for a Wintel x86 box, and the x86 box
is being emulated by... maybe a Java (non-virtual) machine?
This reminds me of a claim I hear in Y2K discussions, but can hardly
believe: that businesses are running the same *executables* since
the 1950s/60s/70s, and that they don't have the source code to fix it.
Sure, they might not have the source to the OS, but their own apps?
And that there's been no other reason to change or replace the
programs in all these years, and Y2K is the only reason they need to do it?
