STB Dual Serial Card - EEFF.ADF


This card seems to be a clone of the IBM Dual Async card and can seemingly use the same ADF. It shares the same card-ID as the IBM adapter. I have no idea where the STB ADF would be.
FCC ID: EKS56APS2DUALSER - Granted 08/31/1988

I have nearly no information on this adapter! If you know something about it, or have any documentation please drop me a line!
