Right. But I guess what I trying to was was more about me being

ordered by date).
I'm not surprised there's an undocumented opcode. I'm surprised to
think it's older and was removed. That's not the usual trend.

I looked at
the firmware disassemblies. Opcode 10 appears to only
point to code (vs NOP) on one version of the firmware

Well, yes, that's my disassembly. So now you know about as much about opcode 10 as I
do. :-)
