"I was wondering if I can get a cable that will hook an IBM CGA, EGA, or VGA
monitor to my ST, will the monitor work?  Also, I have an old commodore 1702
color monitor hooked to my atari 800, is there anyway of making it work on my
ST?"

    Regarding the *GA monitors, I think those are digital whereas the ST
is looking for an analog monitor.
    Regarding the 1702 monitor.... nice idea but it doesn't have the RGB
inputs nor does it have the resolution that the ST requires.  You'd get a
fuzzy image similar to that on your television set even if you could get it
to interface.
    A nice all-around monitor for the ST is the (choke!) Amiga monitor.  Don't
laugh.  It took 'em four years to get a decent one out.  This one includes
composite hook up so that you can plug your VCR into it.  With a mere
flip of the switch, you can have your ST come up via that monitor's RGB
ports.  The one and only one that I saw was very sharp and crisp.  The cost
was under $300.00.
    Beyond those statements I know NOTHING...

   I don't know about cabling for all those other monitors, but I've 
 been using a 1702 for my color display for about a year and a half.
 I'm mostly satisfied with it.  It's true that it doesn't quite* have
 the resolution required for good medium res, but I can stil read the 
 Icons and 80 col. text quite easily.   In low res, the picture is quite
 acceptable, for <blarg> games, and a paint program or two, or doing
 fractals <my faves! Anyone got a better mandelbrot explorer than Fractal
 Mayhem?>. 
 
  
   Cabling it up so it was convienient, however, was evil.  Rather than 
  mess around trying* to find that odd din plug, or shell out large stacks
  of cash for an overpriced switch box, what I ended up doing was making 
  some mods to my SM125.  First, I went and disassembled the monitor plug,
  and ran lines out the back of it for ground, audio and video, soldering
  onto the appropriate pins <which Atari was kind enough to document in that
  cute* li'l owners manual <urk, shoulda said, I've got a 520FM...>>.  That
  was all well and good, and then I went inside the SM125 itself, and spliced 
  a little on/off switch on the monochrome detect line.  One li'l hole later, 
  and a nice inconspicious, difficult to accidently trip switch now is poking 
  out the side of my monitor.  I leave both hooked up all the time, I've been
  very happey with the results.  Total cost:  $195 for the monitor, and $1.25
   for the switch.  


    When I get rich, I'll invest in a nice color Multisync, and dedicate the 
    1702 to running strictly with the VCR <makes  a GREAT TV... best picture 
  I've found yet... :)
