These are two versions of the same program.  I'm not sure if they
are binary identical, but the commenting is somewhat different.

WIZ#A_b10d12 appears to be the more developed version and has
a comment that it s version 1.1 (mod 0) 12/6/78.  However, in
a few places, WIZ#A_b4d7 has better comments than the other.

So here are both.
