One of the Atari 8-bit's most distinctive features is that the program recorder uses one channel for serial data and one for typical sound. This means that you can replay music and spoken words during loading. Based on this feature, Atari released several educational software titles. One of them is the "Atari Speed Reading" course from 1981. In the picture below, you can see Tigerduck and me after we spent the whole evening trying to sample the first tape using a notebook with AudaCity, a hi-fi system, and recoding it back on an audio tape again. It took quite a while, but finally, we found the proper recording and re-recording settings to make it work on the Atari again.
