[time-nuts] Velleman MK153 Single Digit LED Clock Kit

2005-08-02 Thread Brooke Clarke

Hi: The 5060A manual I have is for serial number prefixes 532 (and 528, 516, 512, 504) but does not cover prefix 732 which is my model. Is there a 5060A manual on line that's new enough to cover the 732 prefix? Thanks, Brooke Clarke -- w/Java http://www.PRC68.com w/o Java http://www.pacific
