Video Port Pin Out for AT&T PC 6300.

[Majid Lodhi]

I am trying to hook up a TAXAN 770 + multisync monitor
to AT&T PC 6300. The sync frequency range for the monitor
is 15.75 to 37 khz.

I called TAXAN, I was told that I can use this monitor
but I will have to make an adaptar cable for it. They gave
me the pin out for the monitor.

Unfortunately I could not get the VIDEO PORT PIN OUT for AT&T 6300
to make the adapter.

Any help will be greatly appriciated.

Majid.

My "Hardware Architecture and Function" Manual about the Olivetti M24, which
is exactly the same as the 6300, states the following about the 25 pin display
connector.

1 hsync
2 id0
3 vsync
4 red
5 green
6 blue
7 highlight
8 -
9 -
10 id1
11 mode0
12 mode1
13 -degauss
14..21 gnd
22 pclk
23 blanking
24 +15V
25 +15V

signal description:

red,green,blue,hightlight: positive logic intensity for the 3 guns

mode0: used to select the 512x256 low res mode when 0, 640x400 hires when 1

mode1: "no function at present"

id0,id1 (inputs): display identification. (id1,id0)=(1,0) means color, (1,1)
means monochrome

vsync,hsync: vertical and horizontal synchronization

-degauss: used to activate degaussing, active low

pclk: pixel clock, is 24 MHz or 12 MHz depending on resolution. normally not
used by the display.

blanking: blanking signal. normally not used by the display.

+15V,GND: speak for themselves.
