Atari ST to VGA adaptor

Claes Holmerup
17 Aug 1998

You can use an SVGA monitor with an adaptor cable (which is rather easy to assemble) to get a monochrome picture. Some VGA monitors _may_ work, but all SVGA (or multiscan, multisync or whatever) should work as far as I know.

Here's how you make your adaptor:
connect the mentioned pins

The trick here is that the monochrome signal is fed to all the inputs on the SVGA-monitor, which gives you a very nice monochrome picture. Even though the monitor in fact is a color monitor, you won't be able to see a color picture because of the construction of the computer (and the monitor). If you get your hands on a monitor which handles frequencies down to 15kHz, it's a whole new deal - then you should be able to build yourself a cable with a switch between mono and color (a little more complicated, involving a 4-way switch, but possible all the same). Just about no modern monitors go lower than 30kHz, so in most cases there is no other choice than mono - but since most useful programs (IMHO) run in monochrome, it's the best alternative anyway...

Good luck!
