What is the expected output? What do you see instead?

The effect on real hardware is quite startling: rapid buzzing from the speaker, 
flashing checkerboard pattern on the screen. No escape except for a Reset.

Interesting test case!

I think what's wrong is the memory power-on pattern. Can you please try the 
following in OpenEmulator?

* Start any Apple II
* Enter CALL-151
* Enter 4000:00 00 FF FF
* Enter 4004<4000.5FFFM
* Run your test code.

Does it work as expected?

There's also an additional test for a real Apple II computer:

* Tell me exactly what computer you are using (Apple II, II plus)
* Please do the following right after a cold start (make sure the computer was 
turned off for at least a minute):
  CALL-151
1000.100F 2000.200F 3000.300F 4000.400F 5000.500F 6000.600F 7000.700F 8000.800F 
9000.900F A000.A00F B000.B00F

What do you see?

One last request. Let's test the language card power-on pattern (make sure the 
computer was off for at least a minute before trying this):

CALL-151
C081
C081
F800<F800.FFFFM
C080
D000.D00F
E000.E00F
F000.F00F
C088
D000.D00F
E000.E00F
F000.F00F

Thanks a lot!
