Analogue input for MCL

[straz@cambridge.apple.com (Steve Strassmann)]

There is a large selection of A/D boards. One way to 
get answers to questions like yours is to check an
industry catalog like the Redgate Registry. 

They maintain a comprehensive database of Apple-related
products, and offer online search and retrieval, CD-ROMs
(with demos and screen shots of products) as well
