Hey, just resurrecting this conversation. I purchased a IIsi system a few years back, and it had one of these cards in it. It did not come with the monitor however. I found a gentleman who created an adapter that provides 1024X768 on a separate display. The IIsi also came with a riser card that let you install TWO PDS cards horizontally. I would like to try this card in my SE/30, but the metal chassis prevents the card from natively plugging in to the logic board directly. Wondering if trimming the chassis, or 1-2 PDS straight-through male-female extenders would raise it enough to clear the metal chassis.
Anyway, he’s shipping it back to me and I will test it in my IIsi once it’s recapped and repaired. Will send photos of the adapter as well. Basically, it’s converting the 9 pin signal (whatever it is, TTL, ECL, etc) to VGA, so it’s very interesting nonetheless.
There is a rotary pot on the card, but I’m not sure what it’s for, maybe resolution/frequency?
Here’s a photo of the card I have:
