Welp, after confirming "You're the Dynaflow Doctor" is in fact public domain, I spent a good two hours scanning it in and cleaning it up digitally. I have a high-resolution color copy that's too large to post here (150MB) and this grayscale version at 6MB. It's not a pristine copy but is readable. I've included the test selector quadrant template between pages 32 and 33 since that's where it is called out in the manual. I hope my efforts will help someone down the road, but the manual is at the very least an interesting read.
