Neat. Just a random thought about the random notes is that picking notes from chords over some chord progression might result in more interesting random music. You'd probably need some sort of ROM lookup table to accomplish this in the original design. You can still randomize which specific notes are being played out of the chord (or the scale implied by the chord?)
> my wire-wrapped electronics works perfectly fifty years later<p>Good point there.<p>I once had to debug a (just-made) bad wrap that looked OK but wasn't, and that was it for my troubles with wire-wrap.
That's super cool, does anyone know where to find the schematic?<p>Creating one from the simulator code would do it, but he states that it is an <i>"an abstracted version of the Mind Grenade"</i> so not sure if that means not exactly the original design
