I have installed a Tweety Board in my Mega 2 and I love the sound that it
generates (especially in Zany Golf and Outrun).  It is capable of generating
true stereo output if you have a three channel input receiver.  For those of
us with only amps and speakers, two channels are combined into one channel
on the amp.  The results is the vibrant sound that we all know that the ST is
capable of.

The actual Tweety Board consists of a small board with a pin adaptor to fit
over your Yamaha sound chip, and an external connector with three RCA jacks
to your stereo or amp.  Installation is simple and the documentation is very
good on this.  Installation should take no more than half an hour if you are
good with electronics.  If you are not, then the manual advises you to have a
technical person disassemble your ST.

Things that the Tweety Board does not do well:  it has a problem with digitized
voices (i.e. Playit) because the signal is split into three separate signals,
so digitized voices usually sound pretty funky.  However, turning off your amp
essentially removes Tweety from the system, and you can run your favorite
digitizations from the monitor sound speaker.  Also, my Mega now does not like
anything placed on top of it, so I am going to disassemble it again this
weekend (when everyone is gone).

I highly recommend Tweety Board to anyone who is sick and tired of a great
computer's sound capabilities being wasted.  Put it in your ST and you will
never return to ordinary sound.
