[time-nuts] Re: Neon clock from factory at Motorola years ago

[Bill Notfaded]

Thanks a million Robert you gave me somewhere to start!  I didn't want to
jump without some research first.  I figured it's 12V or 24V DC.  These
were all hooked to a master clock originally but was thinking Pi or Arduino
but using a John M. TimeHat with a new Pi would be neat.  Happy
Thanksgiving everyone.
