- There is some truth in what you say, but in practice the tradeoff is
- pretty acceptable, and the colors are worth the speed reduction. A lot
- of performance loss comes from bank switching the memory. When board
- makers abandon the <386 market and put the frame buffer direct mapped in
- high memory it will improve the display speed. Unfortunately that will
- really hurt on an ISA bus because you only have 16MB of address space.
- Time for EISA or FL bus, preferably VL.
