[comp.sys.att] Needed Pin Outs of AT&T 6300 video cards

GTI@PSUVM.BITNET (Leon Geesey Jr) (05/10/88)

Hi all,
      I'm currently in need of the Pin Outs of the video card
      for the AT&T 6300. This is a DB25 connector, and I need to
      attach it to a DB9 connector on a Kodak DataShow projector.
      This is a device that show the screen image onto an over-head
      projector. Any Help would greatly be appreciated.

                                                Leon Geesey

This came out of the PC 6300 PLUS Hardware Reference but I'm pretty sure
that the PLUS and the 6300 use the same monitor, so the same pin out.

1 Horizontal sync
2 ID0 (tells the controller what display you have) 0=color, 1=mono
3 Vertical sunc
4 Red
5 Green
6 Blue
7 Highlight
8,9 N/C
10 ID1 (tells the controller what display you have) always 1
11 MODE0 0=low res 512x256, 1=hi res 640x400
12 MODE1 not currently used
13 DEGAUSS* active low to degauss a color display
14-21 Ground
22 PCLK pixel clock 24MHz or 12MHz depending on resolution, not used
23 BLANKING one cycle of PCLK3 early with respect to video, not used
24,25 +15VDC power for monochrome display

All of the signals except for ID0 and ID1 are outputs, presumably those
are TTL level inputs. You may have to season to taste for what you are
driving.

Note that the AT&T/Olivetti video is not raster-compatible with
IBM-PC compatible video interfaces that typically use the DB-9
connector.

However, here is the pinout for J5 - the connector for the monitor:

	Pin	Signal Name

	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	GROUND
	22	PCLK
	23	BLANKING
	24 - 25	+15 volts

	ID0 and ID1 identify the type of monitor connected:

	ID0	ID1	Monitor
	0	0	reserved
	0	1	AT&T 318 Color Display
	1	0	reserved
	1	1	AT&T Mono Display
