What I love about the early TASCAM manuals is that they're like a mini audio engineering course, so well written and helpful whether or not you have that particular model.
FYI - Those early manuals were written by the late Dick Rosmini, who worked as a consultant to TEAC/TASCAM during the 70's and into the 80's. He was also responsible for the inclusion of many of the features (particularly in/out & expansion) that were included on the Models 3, 5, 30, 35, 15, 15B & 16, among others.
