The lddevid (load device identity) loads the A register with an integer
that depends on the transputer type. 

My spec of it says that its a NO-OP on the T414a, T414b, T212a and T222c
On the T800b, T800c and T800d it leaves the A register undefined, and
pops the value of C into B.

On the most up-to-date transputers it loads a value into A as follows:

T425  0-9    (there is a range of values for each type)
T805 10-19
T801 20-29
T225 40-49

The details are in the second edition of the INMOS "Transputer Databook"
