Re: EZ-USB

Hi Steve,

Thanks for the reply. We're looking at the CY7C68013, and talking to
the rep's here in Sunnyvale. Also just heard of NetChip, do you know if
it? It's close by also.

Sounds like you'll have a great "black box". Will you write an
application in Windoz for it yourself? How about DOS? Or are there any
drivers for DOS? I hadn't thought of that.
