Summary: ega==>TTL vga==>analog

A while ago we tried to hook up the NEC Multi to an AT&T Targa 24 board and
one of the sync signals from the board was not strong enough for the NEC
monitor to pick up.  The fundamental difference between the EGA and the VGA
is that the EGA is TTL and the VGA is analog.  The NEC works fine with the
PGA (which is what I assume it was designed for) but not with all analog
video sources.  This is what got corected (I think) in the nec II or + or
something like that.

I hope I cleared things up as opposed to clouding the issue.
