22. Insert the driver ICs into the sockets , watch for correct alignment and that no leads are bent under
the chip . The board and socket have a notch marked, as do the chips, be sure all are aligned correctly.
Note that the microprocessor (UP1) faces to the right, and the drivers to the right (as viewed from the
font), as shown below:

23. Discharge yourself to any large metal object, and take the microprocessor from its protective anti-static
bag, and carefully insert it into the socket, watch that the orientation is correct, and that no leads are bent
under the chip.
24. At this point, assembly is complete, and you are ready to connect the power supply and begin testing and
set up of the clock. If you have the split boards, you will also need to connect the units together as per the
circuit board connection chart on the next page.
25. Attach power, and you should see the clock cycle though all the digits 0-9, and then show 12:00:00 (the
combined board will be reversed, don’t worry). It should then begin counting seconds. The clock goes
through the digit cycle only on initial power up, not once the supercap is charged, as it then displays the
stored time. To force the re-cycle, unplug power, and discharge the supercap with a jumper lead, and
then re-attach power.
For the combined cock, you will need to reverse the display sequence, that is
OPTION 52 in the Neonixie software menu, see the attached command set for the clock software
for full instructions. In the menu, you can control virtually every aspect of the clock, and it will
store those settings for future operation. The remote switch board must be attached and working
to access those functions.
Cases:
Any case that appeals to you is satisfactory as long as it prevents accidental shock contact with the HV power
supply, and prevents the nixie tubes from being broken. The split board set allows the most flexibility in
packaging, but is more complex to assemble and wire.
Heat:
Nothing in the kit (at least with out power supply adaptor) gets HOT. Everything should be quite touchable and
only Q100 and L101 get a bit warm during operation, and U9 less so. Case ventilation is useful to avoid thermal
build up that may skew timebase operation, especially with the crystal.
