- VGA is known to be as slow as a dog for certain applications - because
- the memory for the graphics resides on the VGA board, and accessed through
- a slow architecture, the details of which I am not familiar with.
-
- BUT, will the 640x480x8 mode (256 colour) of the Falcon suffer from this
- (I doubt it), or is it memory mapped and consistent with the other graphics
- modes, ie. interleaved bitplanes.
-
- I am particularly interested in this, since if it is similar to the normal
- ST and TT modes, all my local software can trivially port to it, and I
- will not miss the TT-low and TT-medium modes I see on friends' TTs (since
- they are both subsets: 320x480x8 and 640x480x4).
-
- Anyone know yet? And can you say? (Just something like "memory-mapped,
- 8 interleaved bitplanes, just like TT-Low, but with more horiz. rez" will do)
