PAPERs to indices 16-23 and Bright PAPERs to indices 24-31.
a subset of indices 128-255. The number of active indices depends on the number
of attribute bits assigned to INK and PAPER out of the attribute byte. |
Notes:
For the ULA only, INKs are mapped to indices 0-7, Bright INKS to indices 8-15,
In ULANext mode, INKs come from a subset of indices 0-127 and PAPERs come from
In ULA+ mode, the top 64 entries hold the ula+ palette.
The ULA always takes border colour from paper for standard ULA and ULAnext.
