Repairing HP-41CY TURBO from W&W
Hello all,
Finally, I got the HP-41CY TURBO ... Unfortunately, it doesn't work... After putting new batteries I see a "MEMORY LOST"-message only. Nothing happens while pressing the buttons. Any ideas what can be the cause? Some additional questions: - what kind of batterie is used for the W&W-Board - a 3V or 5V? - I found another micro-switch on the W&W-Board - but what for? Any help or a hint is highly appreciated. Kind regards, cellfun |
