Manufacture is Milky Star model is GX-t1tnt/8m
I dug up a few old threads on the old interweb, they were a sister or side company of Galaxy.
I did find a Milky star GX-T2M64 AGP card on ebay that sold october 28 2020, going off that listing i would say the Chipset is ATI Radeon. Other then that i havent found anything on the internet about that specific card.
