I can’t imagine anything like “Color BASIC Unravelled” that could possibly explain how every thing works in macOS, Linux or Windows, for sure!

When I dug my CoCo 3 out in 2014 (?) to begin archive floppies to CoCoSDC, I ran in to a crash on one of the disks. It would literally CRASH the CoCo trying to read it! I somehow figured out there was a bug in the ROM for a particular disk activity, and when I dug through DISK BASIC UNRAVELLED to see what was going on, they had identified it and explained a fix. “Wish I knew then what I know now!” I would have had those books from DAY 1. But it just seemed like gobbly gook to me back then!
