I am working on a project of high speed generation, and what I did was first to
look at the spec sheets of the 6533 (32HS) at www.NatInst.com That is a board
that buffers input and stores it till need be. The 6602 board has counters on
it that can be scanned when events happen. A small bit of math resulting from
those numbers can tell you a lot about when such triggering events happened.
Hope this helps,
Dave
