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

[Andrew Welburn]

There is no bus, to my knowledge.. It's just a slot for the custom video-card to plug into, and another slot for the disk controller. They are not interchangeable.

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....

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.
