Ed:
A few recommendations for troubleshooting.
In /etc/ser2net.conf comment out the 4 default lines (/dev/ttyS0-3)
so that the line Nick provided is the only config present.
Stop ser2net:
/etc/init.d/ser2net stop
then restart:
/etc/init.d/ser2net start
Make sure ser2net is running:
There were some postings on the list for this over the summer.
I think he was going to sell them on Tindie.

The referenced article indicates that they apply the smear to their NTP

the clients to track the servers. This approach would place some limits
on the minimum
lead time you would need to implement the smear.
1) you would have to start early enough for the servers to detect
I replaced one last year.
I used a Delta EFB4012HD from Digi-Key but it isn't in stock currently.
I just looked up the specs on the fan I removed and matched it to
the fans available. There were multiple suitable substitutes.

I saw you post to David on the Time Nuts list offering availability of a
Thunderbolt.
If you have additional units available I would be interested in one as
well.
Let me know if you have any available and the cost.
Thanks,

I am a QEX subscriber and have that issue but I haven't built
the circuit.
The author referenced Brooks Shera as the basis for his work.
He uses a Trimble Resolution T GPS for a PPS reference and an
LPRO-101 Rubidium oscillator for the 10MHz.
His circuit divides the 10MHz output from
of proprietary peripherals
depending on what they envision as it's primary target market.

The PRU on the BeagleBone each include an enhanced capture module that
can be used as you describe.
It has a 32 bit timer that is latched into one of the capture
registers. The timers are independent of
the timer used by the Linux system so I'm not sure how you would tie
them into use with
PRU appears to be unique to TI.
I have only used Raspberry Pi, Beaglebone, and Cubieboard.
The Cubieboard (Allwinner CPU) has a lot of IO pins like the
Beaglebone but nothing like a PRU.

I replaced a fan in a 53132 by looking up the specs
on the existing fan and matching to one that was available.
On the 53132 I used Digi-Key 603-1009-ND.
The fan was part of the power supply as you said.
The wires are soldered to the board.
Good Luck,
