So nice to see Mach people still supporting each other after so many
years. :)

Thanks Tony, I got it running with the low-voltage and apparently
it had something to do with the charge pump, still working that

CMOS circuitry is
usually good for triggering down to 2v, so the 3.5v
Chuck is reading should be enough.? Probably not the
issue, however I have had situations where if running
of 5v then the trigger voltage was about 4.5v, so
maybe.? I wouldn’t rule out a dodgy board or power
supply, but put it a fair way down the list.

I really doubt that it will be too
low a voltage that is the cause.?
The PMDX breakout boards are
quality boards, well designed and will most certainly
be using 74ACT or other buffers that are capable of
dealing with 3.3V voltages.?

looks like for $20. I can get one of these,?
