Atari ST Low/Med Res VGA Cable

[+SoulBuster]

Anyone know where to get one of these? I know, I can build it, but my projects always look like Dr. Frankenstein built them.

 

Is the "15.75 kHz Horizontal sync" a problem? Would an upscaler fix that?

 

Or can someone build one?

VGA Color Cable

This cable allows to connect an Atari running in Med-Low resolution color mode to a VGA/SVGA monitor. The cables use on one side a DIN13 male connector connected to the Atari and on the other side a D-SUB15 male connector connected to the monitor. The Atari is automatically set to Med/Low-resolution mode (pin 4 left open). Note that if you want to hear the sound from the Atari you need an extra audio cable (connected to pin 1) going to an audio connector (e.g. a mini jack or RCA connector).

Important notice: This solution only works if your monitor accepts a 15.75 kHz Horizontal sync (see Connecting Modern LCD/CRT Monitors to an Atari for the video signals charateristics).

Best Electronics sells them.

Yes, the ST's horizontal sync is too slow for most modern monitors, info about compatible LCD monitors here: http://atariage.com/forums/topic/230561-lcd-monitor-that-supports-st-low-res-nec-multisync-lcd-1970vx/

 

Yes with most modern monitors you'd need to use an upscaler.

 

I can make these cables- it's pretty simple if you don't need a colour/mono switch, a bit more effort if you do.

For some reason, I've only just discovered this ... http://coolnovelties.co.uk/coolnovelties/atari-st-video-cables/290-atari-st-to-vga-multi-sync-rgb-colour-monitor-cable.html#/audio_output-with_audio_output

Nice, it's less fiddly to build if you don't need the colour/mono switch.
