There's a patch available on CompuServe to add color to the Flight Simulator running on the RGB input (which is normally only B/W). Here's the information as I pulled it off of CompuServe. I tried a number of different values for the colors (see below) but found none that was better than the one given. Note that it gives "false color" as you might see in a picture from a multi-spectral satellite, rather than the truer colors you get from running Flight Simulator on the composite video. Please let me know if you find any improvements. I didn't understand or use the information below that said: <- this is also saved at 1000:0070 Jim Gillogly I/ / randvax!jim I_/ jim@rand-unix I ------------------------------------------------------------- Flight Simulator RGB Modifications By: Andrew Tuline CIS: 70465,1223 The modifications included herein will allow an RGB monitor to show some colours using the Flight Simulator program. This modification is not perfect, nor is is very well tested. The user should make a copy of their Flight Simulator program using their favourite technique. As we know even the most obvious methods may elude us. Anyways, one of the bugs is, when the user enters the slew mode, the modifications are nullified. Basically, the technique is to intercept the disk vector and setup a port for the colour display adapter for the needed values. I certainly hope, that by disclosing this technique, Microsoft doesn't skin my hide. Anyways to modify your extra spare disk, boot up debug in DOS 2.0 and type the following: Note: you need a system with at least 96K to use this modification as is.

Good luck, and may the colours be with you.
