- In some video modes, yes. In others, no. It's probably fast enough
- to handle any of the 320x200 modes.
-

-
- This raises an interesting point. You couldn't write a faithful Sonic
- the Hedgehog for the Falcon, because Sonic relies heavily on the Sega's
- hardware support for multiple scrolling planes. Put simply, you can
- have two "screens" that are overlapped and can be scrolled at different
- rates.
-
- A DSP won't help you do that kind of thing. The blitter could
- help, but probably not enough to make such things doable with a
- 16Mhz '030.
-
- This is an example of why Atari needed to put a graphics coprocessor
- like the TI34010 on board. Had they done that, the machine might
- actually be competitive in the games market (though more as a game
- console than a computer).
-
- Fortunately for any would-be Sonic writers, the game runs in 320x200
- (or the overlaced derivative; I'm not sure if they overlace it).
-
- >How many people believe that 4 Megabytes should be the lowest amount
- >of memory Atari should include with the Falcon030?
-
- I vote for 4 megs as the minimum.
-
- >Also explain WHY you believe it should be sold with this minimum
- >instead of the others.
-
- You should be able to do double-buffered animation in the 640x480 "true
- color" mode. This requires at least 2 megs; 4 megs for heavy-duty
- stuff.
-
- >Should the Falcon030 have had a graphics coprocessor in it?
-
- Yes, a 34010 or 34020. The companion floating point unit might be
- handy too. (Gotta love having a SPLINE opcode in your instruction
- set.)
-
- >How much of an advantage would the Falcon030 have with a graphics
- >coprocessor in video games?
-
- A *real* graphics coprocessor would make 90's games *possible*. Things
- like Steel Talons, Virtua Racing, and even Sonic the Hedgehog require
- hardware support. The 340x0 series have hardware for drawing lines,
- copying screen regions (= sprites), etc. The situation is similar to
- that of virutal memory: you can do it without hardware support, but you
- wouldn't want to, and it would be really slow. I don't care how fast
- your DSP chip is; you're still going to have to write code for
- Bresenham lines. With a 34010 you'd just load a few registers and then
- do a LINE instruction.
-
- Consider that the late 80's tank game Assault had at least one 34010 in
- it to do the rotation and scaling. (Rumor has it that there are two in
- there, but I'm not sure if that's correct.)
-
- >There is a rumor that the Jaguar will be similar to the Falcon030
- >with a Motorola 68030 16 MHz CPU, but with a 64-bit graphics coprocessor.
- >How many of you believe that this could be possible. Why or why not?
-
- Possible? Anything's possible. I have my doubts about the existance
- of this mythical beast, but "a 64-bit graphics corprocessor" is not
- hard to imagine. If they're designing a custom chip when there are
- already awesome off-the-shelf parts, though, I think they're being very
- foolish.
-
- >If it was possible for Atari to redesign the Falcon030 and incorporate
- >this graphics processor and then slip it into the production line
- >in the middle of next year, do you think it would be a good idea,
- >why or why not?
-
- Yes, they might actually have a prayer if they put a graphics
- coprocessor (not just a silly blitter) in there and marketed a
- game console version of it. (If they could get the game companies
- to write titles for it, of course.)
-
- >How many of you feel that a graphics coprocessor is so important to
- >the success of the Falcon030 that it would be worth delaying the machine
- >another 2 months to include one?
-
- I doubt they could pull that off in 2 months since they've made the
- Falcon a closed architecture (sorry), but if they can, they should.
-
- >How many people believe that Atari should concentrate on music with
- >the Falcon030?
-
- They better do something; they're rapdily losing their MIDI market
- to the Mac and PC. (For which top-of-the-line music software is
- still being written.)
-
- >How many people believe that Atari should concentrate on entertainment
- >with the Falcon030?
-
- I do. But I submit that Atari should drop out of the computer market
- entirely and focus on game consoles, for three reasons:
-
- 1. It's the only thing they can do right, historically speaking.
- 2. There's more money in the console games market than in the home
- computer market.
- 3. The Atari name has been so defiled that it is now a joke in the
- computer industry. It does, however, still carry weight in the
- home video games market in the minds of the moms and pops out
- there who will be buying Junior a game console. Game consoles
- don't require a "company you trust" backing them up like computers
- do.
-
- >How many people believe that the Falcon030 will be WAY underpowered
- >as a home computer in Fall, 1993? And why?
-
- It's way underpowered NOW. Comparison shoppers will look at "16" vs.
- "66" and "50" and "33" and laugh. Programs expand to fill all
- available memory and CPU cycles. Today's "perfectly good" applications
- are tomorrow's "pitifully underpowered" or "difficult to use"
- applications.
-
- >How many people feel that they will be using a Falcon030 in 1995?
-
- Question: How many people feel that Atari will exist in 1995?
-
- >What is your greatest disappointment with the Falcon030?
-
- It is 2-3 years too late, and it is yet ANOTHER Atari machine that is a
- bitch to write games for because it doesn't have the CPU power to drive
- its best games modes.
-
- >What do you think is the greatest advantage that the Falcon030
- >has?
-
- A collection of rabid fans who will buy whatever comes out of Atari,
- regardless of its quality.
-
- >Are you going to buy a Falcon030?
- >
- >If not, WHY?
-
- "Yesterday's hardware at today's prices."
-
- >Do you have a Falcon030 computer already?
-
- No, but I pretend to use one on TV. :)
