- The chunky vs. planar wars are very interesting (from a programmer's point
- of view), but I feel you guys are missing the point.
-
- 1) Both have thier places, but planar provides memory efficiency. Try having
- your word-processor a shell (or workbench) a web browser, etc. all with
- graphics memory on chunky. The Amiga can do this in 1Meg of chip RAM,
- and still have memory left. (3 planes for wb, 4 for your word processor,
- a single bit plane shell and a 8-plane (256 color) screen for your web
- browser in 640K (640x512 resolution) in chunkey, (8bits), you need twice
- the RAM (1280K). RAM is expensive, Many apps do not need the extra
- colors.
-
- 2) Chunky is still very useful, especially for those apps that are going to
- use 256 or more colors anyway. What we need to do is as AmiTech to make
- the next generation (AAA?) chips capable of both. It is only the memory
- fetch that is different, the rest of the hardware could remain the same.
- (With a few tricks, the hardware could display 3 bit (or any other number)
- chunky displays. (They would be a pain to write to, but if you want it...
-
-
- I think planar is important because the Amiga *always* is doing multiple
- tasks, and the memory is more important. No other machine can swap screens
- like the Amiga, and with a chunky-only display, you limit the number of
- screens that you can have open at once.
