I just received my "developer's kit" today.  In it was another "User Reference
Manual" and new floppy disks for version 1.5 of the Soundboard software.

Also included are two new (to me) programs: SBTALKER and DR SBAITSO.

These were not included in my original package.  This leads me to
believe that I bought an "old" package (just how old, I'm not really
sure).

I notice all of the information that I used to construct my macro
assembly interface to CT-VOICE.DRV is not contained in the new user
reference manual.  If you've been unable to make heads-nor-tails of my
code, please accept my appology!  I assumed that everyone had the same
manual with the same appendix.  I'll post a description of the
routines and their use in the near future.  The appendix that I used
is included in the developer's kit.  Also there's a "tip" that explains
why my original polling loop would go into an infinite loop: the compiler
is playing optimization tricks on me and assigning a register instead of
the memory location I wanted!  (I'm not crazy after all) ;-)


I'm also concerned that perhaps I have old hardware.  The new flyer I have on
the SOUNDBLASTER says that the DAC can sample at 23KHz.  The old VOXKIT program
that I have limits sampling to 13KHz.  If I run my RECORD program at > 13KHz
all it does is "speed up" the playback.  Perhaps this is a function of
the CT-VOICE.DRV that came with my original package.  Has anyone tried their
VOXKIT at 23KHz?  I'm going to install the "new" software and see what happens.

The developer's kit looks interesting.  I'll post a "review" of sorts in the
future.

Terry
