    Well, okay, in my experience anyway (but I only ever tried it on one system with a piezo beeper, so take that with a grain of salt.)

    I have no idea, I haven't tried it. TBH, I haven't even tried MagiDuck yet. Though I imagine the difference should at least be measurable since this routine runs once every frame.
    Looking for a cache card for the "ICL ErgoPRO C4/66d V"

    It's called at 24 frames per second. If a frame render takes longer than 24hz the sounds slow down with the framerate, which I suppose works well for sound effects but would not for music.

    I'd be curious to hear this!

    My 6300 had a piezo; it sounded very thin and tinny and quiet, but was otherwise identical to a regular speaker -- all tricks worked, all sampled sound output methods worked. You just had to put your ear to the machine to hear it sometimes.

    I later broke the speaker off of the system and connected two wires to the pads which I then wired to a 3.5" jack that went to my boom box.

    - Music Construction Set, IBM Music Feature edition (has red sticker on front stating IBM Music Feature)
    - Any very old/ugly IBM joystick (such as the Franklin JS-123)
