While not useful, base-infinity numbers should have predictable semantics:
   _b1          NB. Correct in both versions
1
   _b10         NB. Should be _ (correct in J6.01)
_j_.
   _b100        NB. Should be _ (6.01 also incorrect, gives _. instead of _)
_.j_.
   _ #. 1 0     NB. Correct in both versions
_
   _ #. 1 0 0   NB. Correct in both versions
_
   4b_          NB. _ is recognized as a digit, but value is 0 (same in 4b_. 
and J6.01)
0
   4b__         NB. after b, _ can be sign, or infinity, but not both
|ill-formed number

(I also notice that J6.02 finally correctly displays things like _j4
instead of silently ignoring the imaginary part)
