I can't tell what your programmer board does. Do you have Serin pulled to 0V? Does a 10K resistor from that pin to 0V fix the problem?

If not, can you provide a schematic for you programmer PCB? Or is it a Rev-Ed board?

You should have ground going to the 0V pin on that programmer board.
The 0V pin is missing from the adapter!
When we jumped 0V to ground it works!!
The 28M2 and the 08M both load properly. :)
thank you!!
p.s. added cap and 10k
