au/x was an interesting UNIX, but it did have its flaws.
If the system beep occurred, the kernel would lose interrupts. Needless to say, this was not a good thing.
- mikeash 11y agoWhat manner of madness caused this?
- CodeWriter23 11y agoI imagine, the oscillator was software driven, and play_sound (or whatever they called it in the library) disabled interrupts so the sound wouldn't be modified by an interrupt.
- mrpippy 11y agoI'm surprised that would be the case, at least by A/UX 3 the Sound Manager routines were re-routed to call into special A/UX implementations (which I assume wouldn't be disabling interrupts).
