The only ones worth using that I'm aware of are Scream Tracker and Impulse
Tracker and neither was around in the 16 bit ISA days pre-386, IIRC. I
doubt Scream Tracker would be able to function on a 286 anyhow. It puts a
486DX2/66 at about 50% CPU load, from my recollection. The Amiga trackers

Whoa. Interesting problem since a photon carries no charge and thus you
can't horizontally or vertically deflect it with a magnetic field. I guess
that's why folks make things like
