 the truth tables you used also helped me to clarify this, as it
reminded me of venn diagrams.  the rules by which i derive the EOMA
standards is not so much "there are no options" as it is "every option
must be a superset of the other options in the same category".  so
supporting USB1 is ok, supporting USB1 & 2 is ok, supporting *only*
USB2 is *not* ok, neither for CPU Card nor I/O board.  the EEPROM is
similar logic.
