Antic The Atari 8-bit Podcast

Ed Meyer, physical chemistry experiments with Atari computers   In the 1990s, Ed Meyer was a professor at DePaul University in Chicago, where he taught physical chemistry. In August 1990, The Journal of Chemical Education published his article, "An Inexpensive Computer Station for Undergraduate Laboratories Using the Atari 800XL" in which Ed showed how to interface the Atari controller ports with a 12-bit analog-to-digital converter chip to do chemistry experiments. (The article includes schematics and code in assembly language and BASIC.)   From the article:   "The kind of “interfacing” that has been emphasized in chemical education thus far in this country has been largely limited to using the “game paddle inputs” of a home com- puter, which allows the connection of any device that looks like a variable resistor to the computer. This approach has served admirably as an introduction to the power and versa- tility of inexpensive home computers as data collectors and handlers but suffers from significant disad
