A post on the Windows Off Topic mailing list today on multi-monitor reminded me of the fun we had debugging Windows 3.0 applications.
In the early DOS and Windows days (I did this with Windows/386 and up) you could have both a EGA, CGA, or VGA adapter and a Hercules monochrome adapter in your system. The CodeView debugger could be configured to run on the monochrome monitor freeing the Windows GUI from the debugger. You could also re-direct OutputDebugString() output to spew on the monochrome monitor. It was the only way to fly in those days!
Multi-monitor rocks today. And you don’t even have to have 2 monitors connected to your PC to use it. See this blog entry from earlier this year for details on MaxiVista…
