How much RAM can a modern 68SEC000 (which is the one produced still) address?
The 68SEC000 can address 16 megabytes. It's not modern, it's a static version of the 68000.
It would probably be safest to add 2gb of ram and map it from $00000000-$7fffffff, but knock holes in it for chip ram, custom chips, zorro ii/iii cards etc. So you wouldn't actually have 2gb of ram (a lot of PC's suffer with this problem when adding 4gb, especially if you run a 32 bit os).
It wouldn't surprise me if there were more problems than AllocEntry (which would have to completely skip ram above 2gb). There were enough problems with info and installer once you added a 2gb drive for instance.
