That special place in fast RAM is, thanks to MMU magic, exactly the same place ROMs live. ROM code is not relocatable. Therefore, it would be technically correct to claim that you need either an MMU or a 2.0 ROM to run 2.0. While there are some hacks the software folks have developed to let 2.0 run in special RAM locations, these are only for developer testing, nothing suitable for production, far as I know. Therefore, 2.00 was released along with the A3000. Since you could easily switch between 1.3.2 and 2.00, this was not a problem. Later, 2.02 came along, and since it's just a software issue on the A3000, this upgrade was easy. This implies that 2.0x was considered useful for the A3000, though not necessarily ready to be the only OS on a machine, which it would be running from ROM. And I doubt very much how understanding folks would be if you told them they had to go out and by several sets of 2.0x ROMs before the final ROMed 2.0 was complete. I see these software guys working around here every day.
