1.11 +Perhaps the simplest improvement to the display capabilities would be to
1.12 +permit the RGB output levels to "float" between the current TTL high and low
1.13 +states, presumably enforced by various circuits. This would permit the choice
1.14 +of colours beyond the primary and secondary colour selection at a cost of some
1.15 +extra palette bits in the ULA and an adjustment to the board circuitry.
