Have you looked at the python library struct? I don't know anything about the AT&T format but I have been able to read Fortran unformatted data using it. It depends on knowing the number of padding bytes on each line, etc. Anyways, could be useful.

We are working with DSP32C legacy data, and of course it is not a
native type. The original C code is no longer available so this is
our numpy implementation...
Might there be a "better" method to support the AT&T format?
