[comp.sys.ibm.pc] EGA -> VGA on Multiscan

marco@hpmcaa.HP.COM (Marco Dalla-Gasperina) (08/23/88)

I've got a pretty nice Sony Multiscan monitor that has been running
from an EGA type display controller. I've managed to acquire a VGA
card...

The problem is this:

VGA uses a 13(?) pin D connector as opposed to the EGA's 9. My Sony only
has a 9 pin input connector, but is switch selectable for analog inputs
and all the other stuff. Is there a quick way to patch this up so I can 
get VGA on my Multiscan?

thanks in advance,
marco

I have a Sony running on a IBM model 80.  All you have to do is
remap the pinouts to match that of the Sony.
VGA                     Sony
1  red                  ground
2  green                ground
3  blue                 red
4  not used             green
5  ground               blue
6  ground               ground
7  ground               not used
8  ground               horizontal sync
9  no pin               vertical sync
10 ground
11 not used
12 not used
13 horizontal sync
14 vertical sync
15 not used
I made the above remappings based on the sony manual and the vga manual
for a paradise vga plus card.  I made up my own cable that has a 15pin
connector on one end and a 9pin on the other.  Check the pinouts in your
manuals to make sure you make the correct connections.  Sony also
sells a cable for the 15pin connector.

I am interested in getting hold of some of the
'.GIF' picture files that were posted on USENET
some time back. Was a newsgroup created for this
forum? I believe that there was talk of creating
an archive site for the files.

I would really appreciate any help in locating
these files - please reply directly via e-mail.
If anyone else has a similar need, send me e-mail
also, and I will gladly pass on any information I
receive.

Thanx in advance!

Hi...

I have a Nanao multiscan which I am hoping I can eventually use with VGA
too. The last issue of Info-World had a review of some multiscans, with
comments on their usability with VGA. My Nanao wasn't reviewed, but was
mentioned in a box of "also available but not reviewed" units. The
relevance to your request: I think it said there that Nanao and its
dealers had a plug adaptor of some sort. I can't speak for whether your
Sony is otherwise suitable, but I would assume the adaptor wouldn't care
what monitor it was connected to.

Regards,
Bob Wilson

A VGA board can only be used with a monitor that excepts ANALOG RGB
connections.  The NEC MultiSync II is one such monitor, so is a Sony that
I looked at recently (don't remember the number).  If your monitor can
only except digital RGB signals, it can't be used with VGA.

Mr. Video omits one important point.

Most of the Multisync type of monitors CAN be used with many of the VGA
boards on the market. Most boards contain both Analog and Digital ports.

A good example of such a board is the Video 7 VEGA VGA. These can be had
for $229 from 47th Street Computer in NYC.

And, although I didn't say it earlier, the Nanao 8060 does have a switch
(and a front panel LED) for analog vs. digital inputs...

	In a recent artical Daniel Senie brought up the point that most
VGA card have both Digital and Analog output facilities. This is true,
but somewhat misleading. Yes, you can use a VGA on a digital monitor,
*BUT* due to cabling you can only have 64 out of 64 colors ( i.e.
you get all of the colors from the EGA palette at once). Things that
are meant to run in the true VGA/MCGA 256 color mode do not look at all
like they are supposed to and so the only REAL use for the digital jack
is for getting higher resolution on your older monitor ( however,
the 64 color limit still applies to the palette so you get 16 out of 64
colors.. the same as an EGA card)

Now, I'VE got a question.... does anyone have a GOOD color palette already
made up for doing 256 color mandelbrots on a VGA? I can produce the
mandelbrot, but I need a good palette to make it look good.
Thanks,
