Lapis SE/30 DPD to VGA/DB15

With my battery damaged SE/30, I received this Lapis DPD PDS card.

After seeing a few comments from @Bolle (https://68kmla.org/bb/index.php?thr...al-page-video-card-for-macintosh-se-30.45538/), it appears to be possible to get VGA compatible signals out of this card.

The interesting this is that, although my SE/30 came with a 9-Pin ECL connector, the „Video Out“ pins on the board are fitted as well!

Is there a possibility that my card is already prepared for „VGA“ (or standard Mac video out) and I just need a matching cable?

It works! I admit the voltage divider PCB is very crude, but I can now attach a standard Mac monitor or standard VGA monitor to the video card!

If I‘d make a proper PCB, would anybody buy it?

My first self-designed PCB 😎
I‘ll need to source the connectors now..

Thanks 😊

If anyone needs one, I‘d be happy to solder the SMD resistors and give the surplus PCBs away for the cost of shipping.

Sorry for dusting this thread off, but is that offer for that PCB still on the table? I inherited a SE/30 that had this card, and I'd like to see if I can make use of it with a modern display.

I made a new PCB which I‘ll have to test first. Is now only has VGA output and needs the original bracket for the DE-9 connector.

Nice! Looking forward to hearing more about your project!
