Has anyone attempted to use the Atari ST color monitor on a PC using either a CGA or EGA card? Was it successful? Can it be done? If so, where can I get the cables? Matt Singer Commnet Systems

It's timing matches NTSC specs; voltage levels are 1 volt peak-to-peak. It should work with a PGA adaptor (though you might need some voltage level conversion resistors) and might work with a VGA card. It also should work any Amiga. The best place I know of for cables is Practical Solutions in Arizona. (I think that's the name; they make the "Monitor Master"). dgc

I need to replace a CGA/Amdek 310 combination and would just prefer to not have to buy both a video card and a monitor.

Will the ST monitor work on an Amiga, and if so would it be any better in the interlace mode than the Amiga monitor? later Barry

The ST uses an Analog RGB interface, this means the computer tells the monitor how much of each color to use by putting out different voltages on each of the three color lines. The PC CGA adapter uses an RGBI interface; the I stands for intensity (I think). The RGB values are always the same, the I dictates one of two intensities or color sets. The EGA adapter uses RGBII. As you can guess, this is similar to RGBI but carries 4 bits of Intensity data by using two lines. The big thing about "multi-sync" monitors is that they can be driven from Analog RGB, RGBI, or RGBII type interfaces, and at varying vertical sync rates. -- /\ - "Against Stupidity, - {backbones}! /\/\ . /\ - The Gods Themselves - utah-cs!utah-gr! / \/ \/\/ \ - Contend in Vain." - uplherc!sp7040! / U i n T e c h \ - Schiller - obie!wes

You cannot make it work with ANY other IBM video card, as the horizontal and vertical sync rates for those video cards are way off from the standard NTSC values the Atari color monitor uses. -- Michael J.

This may be old news but a friend of mine here in Toronto makes a board (real tiny little sucker... cheap) that will make an analog rgb work with std rgb. tj
