[M100] Mystery Rom in Option Rom slot

[hargarg trurthsr]

I have a model 102 with 32k ram expansion which I got in the 80's. I 
just recently rediscovered it in closet and found some rom installed in 
the option rom slot. It has an eme systems logo on it, but I have no 
idea what it is. I've already tried calling 63012 and 63013 and the 
computer just freezes when I do that. Is there any way to figure out 
what the rom is from basic ?
