[time-nuts] Option 14 on EIP 545A frequency counter

[Scott Burris]

I've acquired an EIP 545A counter which seems to be in decent shape.

In reading through the service manual there is a reference to option 14,
a high resolution mode that increases gate time to 10 seconds.

As far as I can tell, this doesn't appear to be an add-on board.  Anyone
know the details?  Is it a jumper setting?  An entry in the EEPROM?
Different firmware set?  Or something else?

Any pointers would be appreciated.
