Thank you Richard!

To use this cable, I need to replace my video card with a color one. Please, see attached picture of the connector I have on my 386i. I suppose that finding the video card is harder then the cable itself! :-) However, this cable could be a good start for trying to do some reverse engineering of the pinouts.

Since the code I found is different, I supposed that we can assume 630-1621 is the code of monochrome screen/cable.

Hi.

I recently bought a Sun Microsystems 386i and I discovered (too late...) that monitor and keyboard are connected to the same D15 connector on the back using a "Y" cable (I had experience with other Sun workstations, this was first contact with Intel-based hardware).

Unfortunately, I have not such a cable neither I was able to find any info on the web about the pinout/wiring; probably it would be possible to create the cable from scratch (assuming that no other circuitry was inside the original Y cable). Moreover, I discovered that there is more than one option for video boards (mono and color): therefore, there is more than a single Y cable to connect monitor and keyboard.

Looking at the official Sun's hardware list, I found this item:

630-1621     386i video/keyboard cable

but it does not specify whether it is the mono or the color cable. In any case, it seems impossible to buy it on eBay or similar.

Does anybody have some information on how to rebuild it?

Thank you.
