I don't think it's attached to the audio filter on an A1000, but I
could be misremembering. I think they wanted an extra bit and didn't
want to make any of the I/O incompatible when they added a feature.

Exactly. I remember a sinking feeling in my stomach when the machine
would freeze and the light would slowly blink before revealing the
obvious.

Little option as a user, yes. As a developer, sometimes you could
wring some idea of what just happened out of ROMwhack. GOMF was better,
though (because you didn't have to crash and lose and diagnostic messages),
as was a little wedge in the Guru routine that would translate the Guru
numbers into plaintext inside a *huge* red blinky box. I forget what it
was called, but it was handy because it saved much time when diagnosing
what stupid thing you'd done in the code.
