Yo!
I was very lucky to got four Amiga 500 and one Amiga 1200HD. What kind of monitor cable it use? I got one Philips and one Commodore 1084 original monitor too.
Philips seems to have normal Scart female plug on backside. Commodore have two kind of RGB holes (TTL and Lin.).
I am not sure does any of them (Amigas) work, but that the reason I took all five to build one working machine. Problem is only now the cable; where to find it or where to get instruction how to make it myself.
