Haha indeed, it lives! I don't have an RGBI monitor to test with unfortunately. I'm hoping to track one down, or get a converter, as I have an old Tandy 1000 that could also benefit from a CGA monitor.That looks familiar!
I know that it's not related, but have you been able to get a display from the external VGA port?
By the way, many of those BAT files were just for me to quickly get around, and get work done. If you see a D-DRIVE\ directory, those files were copied to my RAM Drive (long time ago) and then they ran much faster. Many of those batch files depended on 4DOS.
