Thanks for the scan! Now, looking at it, the SE/30 compatibility is only mentioned about the Power Portrait (accelerated monochrome); but then, the PV initials everywhere in my card suggests it's a PageView -- GS (grayscale) back then.

Anyway, that ad is from 1992, a bit earlier than my card... and the four VRAM chips on it (42C4064) are indeed 64K x 4 bits = 32 KiB each, for a total 128 KiB. Assuming a 640x870 screen like the APD, that would only allow 1 bit/pixel (monochrome, using about 68 KiB). Not sure if it's accelerated, though.

On the other hand, a copy of Designing Cards and Drivers for the Macintosh II and Macintosh SE is coming my way... I hope it throws some light on this!

The SE/30 didn't include the APD, that came from a previous purchase. No way the Monitor control panel show a different APD resolution choice because... I can't connect the APD to this card :p

I'll try to recognize the card (without any monitor attached!) via its control panel...
