As we all know, 68k Mac compacts have a hardware RAM limit of 4MB. However, there exist accelerators (e.g. Radius Accelerator 16) which extend the memory capacity to 16MB using onboard SIMMs. Presumably 8MB of this RAM is accessible in 24-bit mode.
So my question is, what’s the typical memory map when running on such an accelerator? Is it like the Mac II machines? How are the base addresses changed for the VIA, etc.? Is it as simple as changing the relevant global variables (e.g. viabase)?
