So it's very likely you know about this already, but I'm pretty sure that port was never meant to be connected directly to a monitor. It looks like the PC-9821 shipped with an adapter that allowed you to use the normal JPN-spec analog RGB connection:

This image is totally stolen from this post on the RetroWiki page, which is in Spanish. Or Portuguese. I'm too lazy to figure it out for certain:

So my response doesn't help you with a pinout or anything. But I bet a pinout could be reverse engineered from that adapter if you can pick it up. So your subquest now is, 'Find the Adapter!'

Hi, I was hoping to find the Pinout and make the Adapter myself,
today mount an Adapter to use the Commodore Amiga mouse on the PC9801DS.
I thought I could mount an adapter myself.

I knew about the existence of that adapter, but I wanted to directly mount a cable to VGA, to connect it to the Micomsoft XPC4 and Record some things...,

if i find the adapter or the Pinout of the adapter maybe... ::)


thanks kendrick, greetings.

Edit:

Not 100%100 sure,but i think i got!

looking with words like this "pc9821 ã,¢ãƒŠãƒ­ã,° rgb ãƒ"ンé...ç½®"

i find this:

Here are some interesting images, but that output varies a bit from my Note:

looks good,if someone can see im wrong...i would appreciate it correct me ...,last thing i want is see some smoke  ;D,
i have no rush for build the cable,i prefer wait opinions.
thanks in advance.
