Oh neat!  Is this your puppy then?  You forgot to put your name in the 
source header.

In that case I have a few questions:
1. Was it ever a heath or hug product?  And what was its part number?
2. If so, do you have a production chip?  This listing may have been a 
prelim version.
3. What does the bit of code between 004.116 and 004.216 do?  There are no 
vectors into it from the ROM (and no comments in the source).
4. And what does "AT" stand for?

I guess you didn't find any.  Pam8AT is a 2K ROM instead of a 1K like Pam8 
and Pam8Go.  The upside is now we can embed a document describing the chip's 
history in the unused space.  :-)

Cheers,
