I've got a battery powered peripheral (FM Transmitter) that I'd like to power

I wish to conduct an scientific experiment in wich

I need two datasheets for two Intel Flash chips. So as not to repeat the
embarrasment I suffered last time I asked I have torn the Intel site apart

I hope I'm mailing this to the right group.
My company has a piece of hardware which, among other things, is intended to
provide measurements of the frequency of a clock signal (typically a few
MHz).

for those with nothing to do I found the QLD safety act 2002 below, and I
