- Since the 68030 and the DRAM are on the same card, the extra RAM could
- be addressed above the 16 Mb limit imposed by the A1200 (due to its
- 68EC020). Theres no need to place it in the first 10 Mb range, assuming
- there is no firmware related problems with this.
-
- This is the way the A3000 motherboard fast memory is organized, so
- that a Zorro II memory card could still be placed in one of its slots.
