I have the same book. It says "Compatible with nearly any home computer". I have a full-sized tray loading drive, not the slot-loading Apple Superdrive.
Disk Utility sees each disk as three sections of about 670 MB, 1 KB, and about 670 MB, the first two "Uninitialized", the third the name of the disk, "1925-1964" or "1965-2004". The sizes can't be right because it shows Capacity of about 780 MB. Partition Map is "Not Supported".
If the third section is selected (it is shown in grey as the only volume in the left column) is shows Type as "USB External Physical Volume". Clicking the Mount buttom generates "com.apple.DiskManagement.disenter error 49153.".
Apparently Catalina removed support for HFS disks (not HFS+). Mojave could read, but not write them. Catalina can't even read them. Maybe the HFS code was 32-bit.
