- MCGA is a subset of VGA. It was implemented on bottom-end PS/2's in
- the early years of the PS/2. It stands for Multi Colored Graphics
- Adapter.
-
- It mimics all modes of the MDA/CGA/EGA adapters. It can also do all
- these modes with the 18-bit palette registers of a VGA. If you give
- it full memory (I think this is 256K), you can get 320x200x256 (a-la
- VGA) and 640x480xmono (sort-of VGA).
-
- It also has analog output. It's never been used aside from some
- low-end IBM machines. When a program uses MCGA, they usually refer to
- the VGA-low-res 320x200x256 mode that MCGA also does.
