3.1.7 Thumbwheel Test Program Bug
A bug exists in thumbwheel test 88. To exit thumbwheel test, the test
procedure instructs you to set thumbwheel to "000." If you set any two
digits to "0" and punch the third digit, you may exit the thumbwheel test,
either on first punch or on second punch. The most likely explanation for
this problem is that the processor sees that third digit when the thumbwheel
is between digits, so that as you punch the third digit, the processor sees
"000" and exits the test.
