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.

would freeze and the light would slowly blink before revealing the

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,

as was a little wedge in the Guru routine that would translate the Guru
