Recently, I got a Mac Plus board from a member of these forums for a project that I am working on. I am not far enough in this project to where I need the board, but figured it would be nice to have on hand for when I am ready... and decided to play around with it in the meantime. Since I just have the logic board, I decided to hook it up to a CGA EGA monitor.

Anyways... here are the results:

Normal, low intensity green.

In Amber Monochrome mode

I also have a nice new wallpaper!

Here is a quick schematic, it uses a 74ls04 hex interter, 4 SPST switches to adjust the foreground color (BG is black), and two SPDT switches for both the H Sync select and Video select.
