- Sure, some are fairly primitive, 2-operand designs. But even a two
- operand blitter running 50x faster than the Amiga's is going to be
- significantly faster, if not strictly 50x faster.
-
- Many of the blitter designs over the last few years are supersets of
- IBM's "XGA" specification, which is very Amiga-like: 3 operand blits,
- line draw, area fill, etc. These aren't expensive, either; Tseng Labs,
- for example, has a 32-bit version for under US$20.

-
- That's no different that on the Amiga. Sure, the OS's blit calls are
- designed for the current Amiga blitter, but that wouldn't have been a
- good thing for AAA anymore than for a Tseng or S3 or Matrox chip.

- Hardly. Ever used the Amiga with a 3rd party graphics card? A good one
- is many, many times faster than the built-in Amiga graphics. That is
- the bottom line. Claiming that the Amiga system is great simply
- because Commodore wouldn't pay for its natural evolution is
- ludicrous. What you have in today's Amiga is not what was supposed to
- be there at this point, plain and simple. It needs to be fixed. And
- that fix is not via magic, it's exactly the same problem faced by any
- other OS dealing with software abstractions of hardware resources. The
- primary advantage the Amiga system has here is that the HW and SW are
- steered by the same group.

-
- Just where do you find the Amiga so much more "flexible" over
- something I can buy off the shelf today? Are you just talking about
- the available blits? You can get that. The copper? You can't get
- that. Sprites? Sure, but fairly useless, even in games if you have
- reasonable graphics performance -- realize they were introduced on
- systems like the C64 as a way to make graphics look real fast in
- games, nothing more.
-
- And what you can get today dwarfs anything you'll give up leaving
- today's Amiga chips. You can get built-in MPEG decoding. Built-in
- General MIDI. Built-in 3D acceleration. Just plain old programmable
- DSP-like graphics processors. And graphics buses going 75x times
- faster than the Amiga's graphics bus (S3's 96x series, the new Tseng
- 6000, probably others). Even the difference between the old 68000
- machines and the nastiest, bad-ass '060 based Amiga on the block isn't
- a factor of 75 improvement.
