Thanks Mike for having a look.
I think I made an error in the schematic re. on/off header and the 2 resistors. I wanted 10K to pull down to ground at boot time
and when not running, i.e. header open. This would sink about 0.5mA to ground.
Then I want 5V via 1K (source 5mA) to override the 10K pull down when
switch closes.
Tomorrow I look at it again with your observations in mind.
