The second byte seems to be the most consistent here - 0x4a for the 
models currently handled by the nc code, 0x4d for the tt and z, 0x55 for 
the p. I've no idea whether this is a monotonically increasing version 
string or a bitmask of supported functionality, but it ought to be 
enough to key off to begin with.

Might as well push it and see what happens?
