  Do the ROM_CALL link routines work 82->85,86,89,92? Doubtful. The 
poster said something about 82 & 85 routines.
   Can anyone else confirm that the Ztetris link routines don't work 
with low batteries? I haven't had the problem.

  Also, when the batteries are low, does the calculator's interrupt 
speed gets slowed/quickened? 
   That would be the only reason that I can think of for the link 
routines to not work(too fast/too slow to transmit data correctly). If 
that's the problem, then the poster(can't remember name) should try 
setting the calc interrupt speed slightly higher before sending 
data(then resetting after data recieved/sent), that way when it slows 
down due to low batteries, the routines will still work?
   Before sending data in Ztetris v1.3, I set the speed to %00000010.
