- Standard answer #3: "It depends."

- That 9MB limit is imposed on the standard 68K. The 68K actually has
- access to 16 MB of memory space, but the remaining 7 MB is "mapped" to
- specific things and is not accesable to you as RAM.

- You're not using a standard 68K. 4 MB of that memory is on your
- accelerator. SO, it just MIGHT work. If everything is working and
- clever enough, the 4 MB on your accelerator will be mapped to the memory
- space above the 16 MB limit of a 68K, leaving you with a full 9MB to fill
- up on the main board. 1 MB is spoken for by the GGII. 2 MB comes from
- the SCSI controller. So you theoretically have room for 6 more MB.
