Technical Detail
In order to increase memory bandwidth, the Chip RAM data bus was extended to 32-bit width (as in the A3000) and the Alice chip (replacing OCS/ECS Agnus) was improved to be able to support full width access for bitplane DMA. Additionally, the memory clock was doubled.
Lisa (replacing former Denise) added support for 8-bit bitplane data fetches, 256 instances of 24-bit palette registers, and for 32-bit data transfer for bitplane graphic and sprites.
The rest of the chipset remained unchanged, as did the Blitter and Copper coprocessors in Alice, still working on 16-bit data.

Famous quotes containing the words technical and/or detail:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
“General scepticism is the live mental attitude of refusing to conclude. It is a permanent torpor of the will, renewing itself in detail towards each successive thesis that offers, and you can no more kill it off by logic than you can kill off obstinacy or practical joking.”
—William James (1842–1910)
