Macintosh SE FDHD Video card

Posted by: Scout on 2021-01-09 12:50:41 Trying to identify this card.  Any ideas?  Has a 15 pin VGA and DB-9 port.  New to the site.   I appreciate any information.   My first Compact Mac.  Picked it up a year ago and am trying to learn about it. Will not be my last.

Posted by: cheesestraws on 2021-01-09 13:00:36 "FPD" usually stands for Full Page Display.  Whose full page display card this is, I don't know, but that's the rough class of card it is.

Posted by: apm on 2021-01-10 14:09:30 It uses the same CPLD as a video card for the Portable which @stepleton and I reverse engineered: https://github.com/apmcpherson/VideoMacPacHack We found the 57.2832MHz oscillator was used to produce a resolution for the Apple Portrait Display (or a full-page display by Sunkyung, according to the control panel). So maybe it would drive an Apple display, but only in 1-bit monochrome since it's an SE. No idea whether the overall design is close enough to the card on the Portable (I doubt it), but you could try the VideoMacPac software at the link above. Or look for anything based on Lapis DisplayServer, which I think a lot of these CPLD designs used. Given the lack of ROM chip on the board it probably needs drivers to run.
