- Interesting. I had a look on my IIfx, and my StripAddress entry point
- is at 4080D76C--that is, my StripAddress routine consists of only the
- last two of the above instructions. The preceding BTST and BNE are still
- there, in the same place, but they're not part of StripAddress. Not
- according to MacsBug, anyway.

- My machine is running in 24-bit mode. Maybe I should go home and check
- my LC (which runs in 32-bit mode) and see if that agrees with Keith...
