I am going to increase my use of charts and spec lists in order to provide
a more informative and fact filled comparison of the Amiga, Macintosh, and ST
computer lines. You can look forward to a complete feature list of the Mac
Classic versus the Amiga 500 in the near future, along with prices. I will
also be giving a spec list comparison of the TT and Amiga 3000 line, complete
with pricing information too. What follows is a list of the video modes found
in the Amiga as compared to the new Atari line. Any words inside of brackets
are my own...
[The following list came from page 28 of the February 1991 issue of Atari's
Start magazine. It is the complete video mode list from a review of the TT.]
ST Modes: [Old ST mode list]
320x200 16 colors ST Low Res (Color)
640x200 4 colors ST Med Res (Color)
640x400 1 color ST HighRes (Mono) [Requires a monochrome monitor]
New TT Modes: [Found in the new STE and TT computers]
320x200 16 colors
640x200 4 colors
640x400 2 colors (Duochrome)
640x480 16 colors
1280x960 1 color TTM194 monitor required [What the A2024 is to the Amiga]
320x480 256 colors Many-color-mode from a palette of 4,096
[The following Amiga video mode list was compiled by Joe Smith (jms@tardis.
Tymnet.COM) and has been reposted for this comparison.]
Question: What display modes does the Amiga have?
Answer: Lots.
Mode NTSC PAL ECS Hfreq Colors Palette
-------------------- -------- -------- --- ----- ------ -------
Lores 320x200 320x256 no 15KHz 32 4096
Lores-ExtraHalfBrite 320x200 320x256 no* 15KHz 64 4096 (restricted)

Super-Hires 1280x200 1280x256 yes 15KHz 4 64 (35 nanosecond)
Lores-Interlaced 320x400 320x512 no 15KHz 32 4096
Lores-EHB-Interlaced 320x400 320x512 no* 15KHz 64 4096 (restricted)
Lores-HAM-Interlaced 320x400 320x512 no 15KHz 4096 4096 (restricted)
Hires-Interlaced 640x400 640x512 no 15KHz 16 4096
Super-Hires-Interlaced 1280x400 1280x512 yes 15KHz 4 64 (35 nanosecond)
VGA-ExtraLores 160x480 same yes 31KHz 32 4096
VGA-Lores 320x480 same yes 31KHz 16 4096
Productivity 640x480 same yes 31KHz 4 64
VGA-ExtraLores-Interaced 160x960 same yes 31KHz 32 4096
VGA-Lores-Interlaced 320x960 same yes 31KHz 16 4096
Productivity-Interlaced 640x960 same yes 31KHz 4 64
A2024-10Hz 1008x800 1008x1024 no special 4 16 shades of gray
A2024-15Hz 1008x800 1008x1024 no special 4 16 shades of gray
Notes:
* Some early A1000's did not have ExtraHalfBrite. It is easy to upgrade.
* The 2nd 32 colors of EHB mode are restricted. They are the same as the
first 32 colors with the red, green, and blue values reduced to one half.
* HAM mode (Hold And Modify mode) allows all 4096 colors to be displayed,
but has restrictions affecting adjacent pixels of differing colors.
[Please also note that the above mode list is not showing their perspective
values in overscan, meaning- most of the above resoulitions will increase
their X and Y values simply by using overscan. IE: A 640x400 mode can go to
704x440 or higher in overscan. Also note that a new mode has been created via
some recent software tricks: 704x440 in 4096 different colors. These are true
colors and not "shadings" or "blendings".]

Why purchase a MAC when an Amiga with the same CPU will run 99% of all
__ MAC software..and FASTER at that?! The same can be said of the IBM and
__/// Atari computers, and I can run those in a window. IBM's greatest sales
\XX/ tool is ignorance on the consumer's part. Only the Amiga! DEVO Anyone?
