Seems what I am looking for is becoming very rare and hard to get. I can see vector scopes everywhere but looking at its input, it does not seem to do what I wantl
What I really want to do is to render an image from HP8568/HP8566 and HP85662A on a larger screen. Aforementioned setup has X, Y, Z, and BLANK output. Most oscilloscopes lack BLANK, it seems. None of mine has it. I even thought of buying a new scope just to use it as a XYZB to VGA converter, but that doesn't seem to be a good fit either. I have never done FPGA so that's not a viable route.
Seems vector type anything is popular among vintage video game cloud. Maybe they got'em all?
HOW ELSE can I get this done?? Maybe go all the way IN and replace this CRT with VGA in 85662 and tap the output? That'll be about $700. Ouch.
