>From what Russ and others have said the DRI sound board when it was 
available sounded like a good deal, although, based on all your comments,
it lacked about $20 worth of reliable connectors (IDS, etc..) and 
proper register latching to maintain output signals (on the I/O ports)
while reading the input ports and preventing the application from an
external I/O bus conflict (say Joystick inputs interfering with the output
signals...)  - because of the bi-directional bus on the chip.  If this
is not the case (I will not know until I can see a wiring diagram or such)
then they are retailing (without the expensive connectors I'll be using)
the device for the cost it will take me to produce mine.  If I do sell
to other than just friends, do I have to charge sales tax?  What are the
legalities here?  Do I need a CPA?   Are there any other S-100 sound
boards out there?

Cheers,
