Hi,

I am seeking info on how to develop a device driver in Pascal in
general and under Delphi 3.0 in particular.

I would like to be able to sample from the microphone input socket of
my PC. The idea is to create a very simple A to D converter.
Portability is not currently an issue, it would only have to work on
the one machine. Obviously given some success I want to broaden it
applicability.

Advice and pointers to books, references, sample code would be much
appreciated.

Any specific tools required?

Many thanks.
