Look into sync-isolation for 80x25 RAM NINE about waitvid.2048

Having now more (spare) time in the loader we may well try cleaning up palette values in there.

:colN           rdword  2-2, phsb               '  +0 = read palette entry
                ...
                add     :colN, dst1             '  +4   advance destination

will become

                rdword  colN, phsb              '  +0 = read palette entry
                ...
                andn    colN, smsk              '       %%0003 * $01010101
                or      colN, idle              '       hv_idle
:colN           mov     2-2, colN               '       store palette
                add     $-1, dst1               '       advance destination

Fixed with a53c79c.

@lutherjohnson: The user palette is now allowed to be dirty, the sync bits get cleaned up during line load.
