Thë sound of an IBM master clock every hour.
For some reasons my connected slaves are always 3 minutes behind the masterclock. Anyone who can help me?
See laso http://www.youtube.com/user/janl01#p/a/u/0/8XNmwORkAdc for a better vision.
Also wanted a manual for this clock.

I have an IBM slave clock, but I haven't powered it up yet. It's a square clock from the early 1950s that I got from the middle school near my house when they renovated a while back. I also know another school in my home town with IBM clocks, but they have a Simplex 6400 master clock system controlling the whole building.
