I just downloaded an animation disk. It had Poms 48,49,50 as well as Toolbax
mags 1-6 ... andway .. Toolbox Mag 3 has a music player (like soundsmith,
soniq tracker/mod zap .. all the usually ones) in the bottom border of the
screen ... At first I didn't realize .. but it's pritty impressive! .. Different
colours too!
