I've been busy lately chasing down all sorts of data,  and I *think* that
maybe I snagged a data sheet on that one,  maybe even some application
notes...

I'm not sure just yet as I'm busy sorting a lot of that stuff out,  and
cleaning it up.  m$-junk!  I've reduced the sizes of some files from over
30k to down around 4k,  just by taking out un-needed junk that m$ crap
software puts in there.  So far I've decided that "word" has to
be the worst tool ever for doing HTML files.

Anyhow,  I'll see what I've got here,  after a bit.
