Wow, you really have to know that there is a switch there.
Page 8 has been erased and CAT 2 is now working as expected, time to leave for another family reunion.
Tomorrow, I have to clear the page 8 of the 2nd bank, carefully read J├╝rgen's instructions and then reinstall -RAMBOX 64a & -RAMBOX 64b ROM's.
Thank you!
