HP 55 Bad Key Row Message #1 Posted by Ed on 10 Apr 2001, 2:11 p.m.
My HP 55's last key row ("divide","0",".","R/S") suddenly started acting like the Enter key row ("ENTER","CHS","EEX","CLS")
Any suggestions?
Thanks, Ed

It sounds like you have a short between the traces between those rows on the pcb board. I would take it apart and see if there is some contaminant causing the problem.
Go back to the main exhibit hall
