Jeff G:

Can you suggest a specific thing for me to try or to study, to make
progress?

Where I left this work was that we can issue an unsolicited PIO op
xA0:03 "REQUEST SENSE" (for a multiple of four bytes) immediately after
op xA1 "IDENTIFY" ... but later we cannot inject even a PIO op x00
"NOP".

I imagine somehow interrupt handling is the issue?
