I am building a cga-vga adapter. I've looked around and found that the ones offered for sale at online stores are the wrong pinouts. Here are the pinouts I have:
CGA video
Type: DE9
Pin Function
1 GND
2 GND
3 red
4 green
5 blue
6 intensity
7 reserved
8 horizontal sync
9 vertical sync
VGA 15-pin Video
Type:HD DE15
Pin Function
1 red
2 green
3 blue
4 reserved
5 reserved
6 red return
7 green return
8 blue return
9 key (no pin)
10 GND
11 monitor sense 0
12 monitor sense 1
13 horizontal sync
14 vertical sync
15 reserved
As far as I can tell, the adapter would have to look like this:
1,2-10 GND
3-1 Red
4-2 Green
5-3 Blue
6 Intensity (not connected)
7-15 or nc reserved(for what?)
8-13 horizontil hold
9-14 vertical hold
Does this look right? I'm working from pinouts got online from here: http://www.pinouts.org.uk/pageindex.php
this whole thing is to get a picture from this Headstart Explorer.
