Actual soldering starts at around 17:00.
Here's some film of me making an RGB to VGA converter for the Japanese NEC PC-98 line of computers. These use a 15-pin DA15 (sometimes incorrectly called DB15) connector, by recycling the shell of a Macintosh DA15 → VGA converter with some fresh wiring and new D-sub connectors.
Sorry for the audio delay. Still working on figuring this whole recording thing out; I like the hybrid desktop/camera setup, but need to figure this out.
Sorry for the shaky hands. Just had done a lot of heavy lifting and was excited; hands stopped shaking a little later in the day. Not sure what the deal was there.
I had to desolder all the components from the adapter's original PCB, cut all the traces, and re-use it to hold the connectors together. Could probably have made my own board, but I've never done it before and didn't want to start trying to figure it out now when I'm trying to get things done quickly.
If anyone wants to make a 3D printed model for a DA15 ←→ DE9/HD15 (VGA) sized plug converter, you'd be my hero. :)
Might do a video on the PC-98 (actually an Epson PC-486GR) soon - especially if it turns out to actually work. Fingers crossed that the battery didn't leak badly while it was in storage with the last owner and kill it. Maybe I'll luck out and it's a coin cell instead of a NiCad.
At 16:45 or so I say I am going to use my "Dell U2410M" - that's a model number that doesn't exist. I meant to say U2410H. My other monitor is a U2412M, which is what caused the confusion. U2412m will likely NOT support the PC-98's 24KHz horizontal sync pulse rate - but the U2410H will, and will also support 15KHz RGB.
