-
- This is one reason why we should do our own WAD files so we can optimize them
- for Bad Mood to let them be as fast as possible.

- Nope, but it's very nice running in 160x100. :-))) The graphics will not be
- pretty, but it will be speedy. :-)

-
- I think I will get an accelrator soon to be able to play Bad Mood at full speed.
- :-) I wonder if the FX-card will ever get that "turbo" mode with a transfer rate
- of 20MB/s insteed of 8MB/s. Have anyone heard anything abou this, or are the
- BlowUp guys only dreaming?

-
- I do wonder this too, but this is what they have said (among alot of other things
- that havn't turned up yet). Is the 960001 compatible with the 56001? Maybe
- there is a DSP from TexasInstruments that are 56001 compatible (I don't think so)?
-

-
- Ofcourse. They have said that the Hawk will be 100% compatible with the falcon.

-
- How should they do it then. The falcon just can't handle higher clockrates and
- doesn't have a true 32 bit bus.
- The only way to do it is like this or like the FX-card, but the Hawk will
- be _much_ faster. Wizztronic have said that it's even faster than the
- Afterburner. I guess the 256kbyte cache is responsible for this and that it
- depend on how you compare them.
-
- > If they do that much, they could almost as well make a complete computer.
-
- There will also be a graphics card for the Hawk....
-
- > Of course, they've said that they are doing that now...
-
- Yup, but as I said, they have said many things but nothing have turned up yet...
