David's ST Graphics Card v0.2

Further to throwing ideas around, and I know its drifting from STFM/e a bit, but it may invoke other areas of study...


Is there any way we can memory map an address range for something like what you are building to the TTRAM only address range?

Although this would exclude the STRAM/ALTRAM blitter access, the full 32Mhz+ CPU read/write access speed would make up for it.

The advantage to using the lower 16MB range is that a) it'll work with 68000 but also b) is blitterable. But if it's located on an accelerated bus it'll still be accelerated.

There's nothing to stop a 32 bit board having 32 bit access to its own AltRAM.
