I have an AT clone running Microport 2.2, and an avid
interest in meteorology. I'm in a research phase, and
want to do the following:

1. Sample barometric pressure.
2. Sample wind vectors.
3. Sample temperature.
4. Sample relative humidity.

I am confident of my ability to manipulate the data once I
have collected it. I am not at all familiar with how to 
interface analog devices. I would like to purchase  or
construct a weather station that can be interfaced through
an extra rs232 port on this machine. The sampling times
are not microsecond critical, so sampling rates are flexible.

I seem to remember such a device was available from Heathkit.
Does anyone have any experience/guidance to offer along these
lines? I want to avoid special purpose boards which are widely
available because of the kernel hacking that would require.
 
Please respond to me by mail, and I will summarize as 
appropriate.
