If 7.1 was installed on LC/LCII/ClassicII-type Macs, and if memory control
panel was set to 24 bit addressing, would that yield 8MB or 10MB of RAM?
Hey Gamba, I tried it last night. On a Classic II, you get exactly the same amount of available memory (10MB, according to the "about this Mac" panel) for both 24bit and 32bit addressing.
As these machines don't have any NuBus slots, perhaps the ROM uses the 68030 MMU to add the extra RAM into that space. I sure would like to see a memory map of these machines.
OS 6.0.8L will not install on a IIci.
