[time-nuts] TymServe TS2100 dead power supply

[paul swed]

I have built an irig b encoder. Irig uses a 1 KHZ amplitude modulated
signal. I can't remember now if it was pulse width modulation also. But it
used a small processor and todays arduino is many time more effective at
the job.
That said I used a modulator using a small xtal controlled divider to
produce the carrier. It was a Epson chip and even the xtal was built in and
a analog CMOS gate as the modulator.
Its actually fairly simple to create.
Then it was a case of reading out the clock in the correct format.
Regards
Paul.
