|Summary||07455: ti83: Freeze after Q pressed|
Normal operation is to press Q to turn it on, and it will say "Mem cleared", with flashing cursor.
Then press Esc for a full screen of various settings.
Now, after pressing Q the cursor appears, not flashing, and the machine no longer responds.

Specific commits in question (probably the first commit) On October 18, 2014:
My binaries work AM 10/18 and broken AM 10/19. Only z80 would be at fault and there are no commits on that day for z80.

The 2nd commit simply comments out unused variables, and therefore has no effect on this bug.
The 1st commit has a number of major changes for other calculators (not the ti83 specifically), but I conjecture that it was caught up in the backwash somehow.
The debugger seems to indicate that when Q is pressed, the interrupt fires, but does not clear, so it gets caught up in a loop.

|Current behaviour, the first press of Q does nothing, press again, it quickly flashes "mem cleared" then solid cursor and hangs.|
