Falcon CA401332-003 Rev D/C Service blog

@DoG you beat me to it, I've done the same to make db23 plugs for use on an Amiga.

[Steve]

@DoG yeah I did worry about the diameter of these pins too. I'll test their continuity later.

[Steve]

Yeah turns out those pins weren't thick enough. Used different types now, soldered with solder paste and heat gun again. Then sealed with araldite crystal clear epoxy.

Nice work there, very tidy! This will extend further out the back of the Falcon than the other ports, though, right? Do you think that looks better than the cut down DB25 solution?

[Steve]

I'll find out once it's on. To be honest it's going to be a large improvement over the gaping hole it had before

[Rustynutt]

Guess those are a bit of time to find, remember Willy asking over a year ago for some AIRC.
Love innovation

Will follow the instability of the CT60.
A user (member?) about 3 hours from me and I have been messaging near real time troubleshooting his setup.

Have a buffer board now verified installed properly, and he learned the "don't forget the expansion jumper" rule

wow, thats quite amazing, so im guessing the video port connectors are hard to come by ?

Apparently they are not produced at all and the only types you can find online are female versions.

[DoG]

There are male version out there but that is for soldering wires to. Someone did a rerun of them a couple of years ago. But right angle ones for PCB seems impossible to find.

[Steve]

I might need some help from another pair of eyes My first attempt at the db19 didn't work. So I've tried directly wiring a VGA connector. This also doesn't work. I'll post a photo of my wiring above and below, could someone check it out for me? Thanks

The above patch wires are:

• Pin 14 (Vsync) to L31 positive, as the top trace was broken.
• Pin 11 to 5 (gnd to gnd)
