I saw an NEC Multisync in a thrift shop today. Looks
like a nice
monitor, can do TTL and analog inputs. Could someone tell me what
exactly are the modes that it does? Also, are there any monitors like
this that can also take VGA inputs in addition?
If this is the original NEC Multisync it will do anything from MDA to SVGA
800 X 600.
The connector is a 9 pin MDA/CGA/EGA type but there is a digital/analogue
switch that will allow VGA and SVGA if set that way.
To use as a VGA you need an adaptor cable known as a "Multisync" cable which
is 9 pin F to 15 pin F. Readily available and about $5 around here.
I used to keep a bunch of different monitors around until I found what these
can do. Another benefit is that they are usually very cheap because most
people think they are only EGA.
