However, if I recall (don't have a FAR/AIM book in front of me), above
10,000 MSL is Class A airspace and it does require a transponder, yes?

I think 91.215(b) makes it pretty clear that a transponder is required:

(4) All aircraft in all airspace above the ceiling and within the
lateral boundaries of a Class B or Class C airspace area designated
for an airport upward to 10,000 feet MSL


I didn't fully qualify this, above 10,000 feet MSL a transponder is not
required, even if you are within the lateral boundaries of B or C
airspace...
