I could help, but I'm not in Seattle!

Here is an exact list:

Test for 128 Ram - okay

Test from left to right buttons: all okay, give the test beep, except for--

#29 (arrow left)
#34 (division)
#39 (multiplication)
#44 (subtraction)
#49 (addition)

these buttons do not give the test beep and do not compute.

Thanks.
