What is this card I have in my SE/30 ?

[MHarding]

I've recently bought myself a Macintosh SE/30, and found this card mounted on the analog boards power socket.
It has "(C) 1988 ASK LCD" stamped on the PCB and has a 9 pin output on the back of the SE/30.
I assume it's for an external monitor of some sort. When googling I came up with almost nothing, apart from finding a company called "ASK Projectors".
Searching for "ASK LCD" gives lots of misleading hits.....

Assuming it's for an external monitor, does anyone know what type/model of external monitor I can attach ?

It's a cloning video output adapter, so you could display the B&W image externally on a projector; something like a TTL/monochrome monitor might do it but be prepared for some tinkering.

I think there was probably some other circuitry to attach to that board to provide video output to some other device. The logic chip there is probably being used as a buffer to drive those lines without affecting internal video. Compact mac video is hsync, vsync and 1-bit pixel data - no monitor I know of takes that directly.

Highly likely for a LCD panel that went on overhead projectors, I had a few teachers that had these.

Thanks. Think you're right
I don't think I'll ever find a LCD panel for it, must be "unobtainium" by now, or buy an overhead projector....
Could have been a really fantastic setup though, for showing off
