Hello all,

I've been working on some special sound code for the HP48 for 
a while, and although not in its final form, I wanted to share
with you all some of what I've done so far.

The SND directory contains 6 different sounds, which I think you'll
find interesting.  They are a far cry from the simple sounds that the
HP normally lets you create.

Incidentally, this stuff is written in machine language, so for 
all the diehard system-rpl programmers out there, try doing _this_ 
in system-rpl  :-)

SCALE.BIN: the 12 notes in one octave, going up the scale       0.86_s
LASER: series of quick sweeps down; sci-fi movie laser noise    0.68_s
ALARM.BIN: 4 sweeps up (another good alarm clock sound)         1.31_s
PHASER: rapid high/low tones; reminiscent of Star Trek          0.72_s
