TOPIC



    I recently tried using some older software, which required an older version of MS-DOS, with our 6100 DOS Compatible computer. I kept getting "Incompatible Version of DOS" when I tried running the application. If I tried using a disk that had the older version of MS-DOS on it, I got a "Wrong DOS Version, Cannot Load COMMAND.COM" error message. Can the DOS Compatibility Card use older versions of MS-DOS?

    Also can the DOS Compatibility Card display CGA graphics on Apple Displays? When I tried the screen lost sync and the image was unusable.


DISCUSSION


    Only DOS 6.0 and higher are supported on the DOS Compatibility Card. These versions are the only ones tested and supported. There are no plans to test older versions of MS-DOS, or try to get them running on the DOS Compatibility Card.

    The problems with CGA applications is that Apple monitors do not support this display mode. The documentation for the DOS Compatibility Card explains that the VGA controller is backward compatible with EGA, CGA and MDA. But in order to use it in other modes, you need a third party monitor capable of displaying CGA graphics.
