So I finished my 10mhz frequency standard.
I like to build another project, this time a programmable frequency source which can be either clocked by the bbc standard or from a ex mil crystal oven osc I just got on ebay.
If possible I like the thumbwheel readout to equal frequency, ie 000500 = 500hz, I at first thought of 4522's and invert the o/p's of the thumbwheel switches, but thats not gonna work.
Any ideas.
