-
- What I'm asking is what I'm asking. How bad would be the flicker even
- if the line color and the background color have similar luminance?
-
- Could games like Links Golf in 640x480 be displayed on a television
- without giving you a headache? (A normal TV set, nothing special)
-
-
- I thought the reason the Amiga flickers is because of its interlaced video, no?

-
- This is why I was confused. This chart is from Atari Advantage Magazine,
- it was provided by John Townsend of Atari.

- True normal TV 320x200
- 4 interlace TV 320x400

-
- Now, I pretty much understand that the TV will display 320x200 without
- interlace. But, according to the above, it will not display 320x400 without
- using interlaced video.
-
- The second part does not mention TV at all or interlace. All it mentions
- is "vga" and that is probably where I'm getting lost.
-
- Is the "vga" overscanned? But the "tv" is capable of being overscanned
- as well, no?

-
- Do you think that average person looking for a low-costing computer
- would be attracted to 4 Megs from a marketing view?
-
- That's at least another $100.
-
- And then you start getting into $899 or $999 and start slipping away
- from $799 or even LOWER...
-
- RAM is not so expensive anymore, but it still raises the price of the
- computer quite a bit.
