Looking good!  Nice example of a white PM noise floor, just like a 'real' HP counter.   Let it run for a few days and see how the environmental sensitivity looks.

Those small SPI LCDs are really neat, especially for the price.  I just used one the other day to replace a 1" CRT in a receiver panadaptor.
