I've been using 60000 since it seems to work on even the 8K RAM machines, at least according to Virtual T, although I admit I don't know how. Does an 8K Model 100 put its memory at the highest addresses and have a hole in the middle?
Yes, an 8K machine would have all 8K in the upper 64K region and then it "grows" downward toward the 32K middle point from there with each 8K installment you add. It does this because all system variables are stored in upper RAM locations and the lower RAM is where files are stored. File storage starts from the lowest available memory location (0x8000 for 32K, 0xA000 for 24K, 0xC000 for 16K and 0xE000 for 8K).
