It's a green screen Philips BM7502/00G.
Is there an ISA interface card that allows me to use it with my 8088 clone?

Looks like it's just a Composite monitor, so if you have a card that has a composite video output, it should work with this monitor.

I need to make a compromise because green phosphor monochrome monitors are super rare here.
I have a few CGA cards but how do I know if it's a composite output or a simple feature connector?

If you connect the monitor to a "Feature Connector" it shouldn't do anything, but if it shows something, then it's a video output.

I don't think CGA cards had feature connectors like EGAs... just a composite output. It may require flipping some dip switches to output to one though. Also for gaming composite out is preferred over RGB.

Depends what games...
Composite provides more colors, RGB - sharper image.
Some games look better with more colors, but others use detailed graphics that's only clearly visible on RGB monitors.

...in colour, with NTSC.

For a mono monitor all it gets you is a slightly fuzzier picture.

That said, I get the impression that almost all the mono monitors you see in Europe are composite, TTL seem as rare as hen's teeth (not that TTL colour is any more common though, I just gave up and went for MCE2VGA eventually)

I remember that with monochrome monitors, it's usually preferable to send the Luma signal to it, as they won't process the chroma correctly, resulting in artifacts on the image.

Ah, true.I havn't noticed it's PAL.

Correct me if I'm wrong but CGA used *NTSC* composite and that looks like a PAL monitor (220V/50Hz).

CGA did indeed output an NTSC composite signal. But this is definitely not a PAL monitor, since PAL is merely the color TV standard and this is clearly a monochrome screen.
That being said, the vertical size and vertical hold adjustments are probably set to 625 lines at 50Hz rather than 525 lines at 60Hz, so you'd have to play with those knobs on the back of the device.

So... the TTL on the Commodore 1080 isn't applicable? [OR perhaps these have gone much more rare than I would have guessed.
