- That's true, but you should also mention what the hardware scrolling is, to stop other
- people from spreading such $%^$!@#$%$ shit. IMHO the so called hardware scrolling is
- just the ability to scroll the screen LEFT or RIGHT in steps of one pixel, which was
- completely impossible on the "normal" ST (unless you'd like to write a program and
- bit-shift it on your own). The UP / DOWN scrolling (ok, ok there's only upscrolling
- in GEMDOS output) can only be done by some kinda program (or the blitter perhaps), but
- in every case a tremendous amount of memory has got to be shiftet. Just a little math:
- (taken from a PC clone) When you're running 1024 * 768 pixels in 256 colours you've
- got to shift 768K of memory to scroll up one single line (text or graphic). I once
- saw this on an 33MHz 386 and it was pretty slow. As far as I'm informed the Falcon
- will not be able to display this resolution, so the memory which needs to be shifted
- will be smaller, but in every case its the multiple amount of the 32k on a "normal" ST,
- so I may very well believe that it may appear "slow". But I think that mocking around
- this or other speed stuff is useless until ever somebody has actually seen a Falcon
- (except developers). And I also think that people should better sit down and think
- twice before spreading such rumours. People always say their computer's too slow and
- they want to buy a new, a faster one, but who really NEEDS this speed? (in general,
- not only ST, but PC clones also).

- P.S.:Please don't write a followup if your computer can display 769 lines, which
- would be one more, so 100/768 percent more and thus better and calling up hundreds
- of other flames...
