Skyles Electronic Works PET 2001 ROM Upgrade

Anyone have a clue what is on the Skyles Electronic Works ROM upgrade?

One of my local, vintage computer merchants in NJ added this to their online store:

Is it just an upgrade to a later ROM like 4.0?

First of all, it says in the description that's for the 2001-32N (so, the 30xx/40xx dynamic RAM models). It plugs in a 24 pin socket (count the pins) so it may be any kind of expansion for the early dynamic PETs.
It's kind of impossible to tell without at least figuring out the complete pinout and/or dumping the two 4Kbytes EPROMs.
