(apparently my original posting to this group got lost in transit, so
this is another attempt at the posting.)



Can anyone supply me with a name and address of a company that
has strip-chart recorders (ie. a device that rolls a paper strip underneath
a pen that moves back and forth depending on the strength of the input
signal to the instrument, thereby yielding a nice "picture" of signal
strength over time).  (Forgive my non-technical description there).

I do not need anything fancy -- this is just for a home project, so the
cheaper the better.  I am thinking about building a simplified radio 
telescope to "listen" to activity on the Sun and would like to hook the
strip chart recorder up to the radio telescope so that I can have a
visual record of the solar activity.

As an alternative, if anyone knows of articles, books, and or schematics 
that show how to hook the output of a device such as the radio telescope
to a computer (old IBM PC) so that the info could be recorded directly
to disk and then graphed later, please send such info also.

Thank you very much.
