HP 67

[DEJR8ISGREAT]

Just bought an HP 67 on EBAY, paid way too much, because of that I thought it would work, put a fresh battery pack in it, and for about 1 minute it did. The fix key did not work....then all 0's were in the display and no key worked to change them, turned it off then on more then a few times, sometimes all 0's or 7's or small dashes. Do I now have a very expensive door stop?
