Can someone explain the differences between VGA CGA EGA and so on...
I don't mean just what they stand for, but also what is the hardware,
or electrical differences.
Thanks, Tom
P.S. The more details the better!

All of the terms ( VGA, EGA, CGA ) are names of different
IBM PC display hardware.
CGA - Color graphis adapter ( old, low res )
EGA - Enhanced graphics adapter ( better than CGA )
VGA - PS2 compatible ( the better than EGA )

from a hardware point of view, you need a monitor that matches
the graphics board. CGA--CGA monitor, EGA--EGA monitor, VGA--VGA
monitor. They all use different frequencies. The CGA and EGA
are digital TTL, the VGA is analog.
That's why multisync monitors are so popular in the ibmpc world.
It gets expensive upgrading the monitor every time the graphics
standard changes. Things like the NEC MULTISYNC II monitor can be
connected to any of those graphic boards.
