Yep 54 hz, not khz, very poor writing on the print that denotes that.

Hopefully Vsync is 54Hz ... needs to be substantially less than HSync.
The quick trick used to be hooking up the H and V to the VGA monitor,
and then simply

I suspect you meant 54.38 Hz. That would be within the reach of an NTSC
monitor. Unfortunately those are limited to those tv's with inp

I guess that board woul work ok since it looks a lot better than mine. If

Also note that VGA works with analog voltages for the RGB and the CRT on
your lathe sure has TTL for the video signal so it wouldn't work without
and adapter board.

Hello Rick.
Sounds like it has the same signals as our Mazak. Probably the working
frequencies are the same as the CGA old monitors. In our case we replaced
the old CRT with an old CGA monitor and connected the video signal to one
of the colors.
But in your case I guess the best would be to get a
Hello Guys,
This is off topic for sure, but knew of no better place to ask with all
