Pulled it out of storage recently knowing I finally had a place to put it permanently. And I can only get Saturn to display on it. N64, PCE, PS1 all give me nothing. Either with straight BNC cables, or using the same SCART -> BNC adapter. They all work fine on my OSSC, and on my CRTs, but not on the plasma. Does it only accept a specific type of sync that these don't all share in common? And if so, is there an Extron box for that (seems there's an extron box for everything, ha)?
My assumption is that, being BNC, the display is expecting RGB with clean, TTL-level (5Vp-p) sync, and won't accept composite video or luma as sync. I believe the Saturn outputs clean sync, which is why you're having success with it. If the Saturn RGB SCART cable brings sync down to 75Ohm (1Vp-p), then that makes things a little easier, in that you won't have to bring up 75Ohm sync from consoles that output that).
The N64 only outputs S-Video at best, so you'll need to RGB mod it first, assuming you haven't already.
Regular PC Engines should be able to output RGB with an adapter on their expansion port, and Duos need an RGB bypass and a Genesis-2-style AV connector installed in the back.
The PS1 outputs RGB natively, but not clean sync (Normally uses composite video for sync), so you'll need a cable with a sync stripper built in, or a hard mod.
