This is an old VGA card. Or maybe even compatible with older standards, because of 3 ROMs here. Chips are cozy warm, caps are holding time to clean the DIP chips, and check/read EPROM. Will it live again? So far no video output. Just one russian forum mentions it :) #hobby #isa #vga #tseng
Thanks to Jarosław Jakubik and his quick share of the ROM contents I was able to move on to the next suspect - RAM. Turnus out the two Goldstar RAM chips are bad and removing the whole 512kB "bank" revived the board. Yay! Now I can hook it up to Atari ST
