Hi all, I'm a retired engineer and clockmaker. So, I suffer from interests in many technical subjects. I recently bought a box of HP series 1740 "Clock Displays". They are marked "good" and seem well packaged. I cannot find any documentation on how to power these clocks. I need maybe two for my personal use and 7 left over for whoever needs one. Please let me know if you have any information on these beautiful clocks. Thanks Steve Get Outlook for Android<https://aka.ms/AAb9ysg>

Steve, Those look like the clock modules from the HP 5061A. I've attached a copy of the schematic and layout for these units. I could use one or two myself if you have some to spare.

I agree with Steve they were a option for the 5061 and I think the 5065 also. But Steve sent you the details to get them going. In my unit the LED vary in brightness on different segments.
