[Techtoolslist] Fluke 9100A monitor output & more....

Just had a look at the IBM CGA connector pin out:

http://nemesis.lonestar.org/reference/video/cga.html

The connector is following the "standard", it's a 9D female connector. The colors are probably on pins 3,4,5 (R,G,B) acc. to the IBM standard. Pin 7 normally carries +12V but is often not used so I guess they put the B/W signal there. Pin 8 and 9 carry Horizontal and Vertical sins (positive) so that's according to the earlier drawing I posted too....

The only really damn tricky pin is nr. 2. The 9100A puts out +5V on it, while the IBM has pin 1 and 2 as GND......

Anyway, let's get out the soldering iron.... oh I need a 04 too....

Do we know anything about that video card by the way ? What is the bus that Fluke used for the SCSI and Video cards ?

Sorry for all the remarks/questions.....I'm pretty hyped about this thing and can't wait to hook it up to my first UUT :)

If in doubt, just scope the outputs and find your RGB and syncs. As stated before, invert each sync signal with an ls04, then join them together to give you composite sync. Then you can feed this to a SCART tv or a regular arcade monitor. Ignore the black and white output.
