Unknown Macintosh SE video adapter
Posted by: Freddruppel on 2021-11-15 09:53:53 TL;DR : Can anyone identify this ? (see pictures) I picked up (yet another) Macintosh today. While doing the classic maintenance things (clean inside, remove PRAM battery, ...) I discovered there was an adapter board hijacking the signals between the motherboard and analog board. It has a 8-pin DIN output connector, of which only 7 pins are used. It also has a white wire labeled "Dot CLK" on this PCB going to the ADB or GLU IC on the motherboard (or at least I guess it was connected to one of those chips, as it was floating above that region disconnected when I opened the Macintosh) The only markings on the PCB say "MAC Video adapter", "FSI 1988", "Made in the USA", "Eastman Kodak" and "P/N 8010 REV E". Does anyone have more info about it ?
