The IBM 5153's True CGA Palette and Color Output

CGA can output 16 digital RGBI colors, and there's a well-known standard palette which translates them to (s)RGB values - but that palette isn't a very good approximation of the colors you actually get on IBM's original CGA monitor.  Why is that, and can we do better?

Using a TV set as a CGA display device has its issues, especially horizontal centering and color in 80-column text mode.  These utilities should help.  There's a bootable version too, so you can throw it at your favorite booter games.

A fully-equipped IBM 5160 braves the rigors of international shipping and gets here in one piece (just barely).  As will be pictorially demonstrated, 30+ years after leaving the factory, this steel warrior is still one tough SOB.

Can you take the original IBM PC color graphics board, and force it to display 32 times as many colors as it's officially capable of?  Believe it, comrade!  Here's the in-depth write-up on how we did that in the 8088 MPH demo, complete with illustrations.

An exercise in taking "modern" graphics software and dragging it kicking and screaming back to the glorious days of clean, simple, 2 bits per pixel raster graphics.  Plus a time-lapse video of the whole process.
