HP-41CX Port 1 and 3 temporarily malfunction
The other day I plugged in the Games-Module into port 1 of my HP-41CX. The machine did not recognize the module (CAT 2). Same result for port 3 (CAT 2). Plugging the module in port 2, CAT 2 resulted in a weird display (flickering of some special characters, BAT annunciator on) followed by a blank display with a locked up machine finally.

Removing and immediately reinstalling the batteries cured the malfunction: CAT 2 showed the Module in any port. Fortunately no "memory lost" occured either.
What could have been the reason for this misconduct?
