@Tenacious:
if you want to use your Amiga to log something, you're going to have to learn to code.
I have a datalogger from DataQ ...specifically:
http://www.dataq.com/products/startkit/di194rs.htmand what I'm using it for is monitoring my wideband o2 sensor readings on my race car. I already have seperate hardware to do this but I wanted to see if I could do it myself. Oh but its on a PC not Amiga.. You can write something on the Amiga to do the same, you just have to look at the specs on the datalogger to see what format its coming in as and code accordingly. It (specs/diagram) provided when you buy that datalogger or you can just ask for it via email before you buy just in case you want to get a head start.
