Nice write-up except for the obviously still incorrect first part. I really don't get why this is such an issue; the correct cable connects pin 1 at one end to pin 1 at the other end, end of story. Connecting pin 1 to pin 2 as you want to do will not work as I've pointed out several times; why would you assume the DVI is at fault when your cable is wrong?
Fortunately the 5V and ground connections are swappable so you probably won't cause any damage. Unfortunately a 24DIP plug that connects pin 1 to wire #1 seems to be pretty rare, and you may have to swap the pins, either the way described in the link below or with a little adapter cable described later in the blog; thanks for attributing the picture BTW. What's odd is that there seem to be all sorts of 28-pin IDC plugs that have the correct configuration, i.e. pin 1 connects to the first wire; why not the 40-pin versions... I'm glad that someone else seems to have at last almost convinced you, since my words and pictures were falling on deaf ears... ;-) BTW, my pictures were of the original cables that came with my DVI when I bought it brand new, plus an extra long one that I made myself. Too bad you scrapped your cable; as I pointed out you could have used your T102 cable to correct the pinout. PIN 1 to PIN 1 ! Simple as that. m ----- Original Message ----- From: Brian White To: m...@bitchin100.com Sent: Thursday, October 26, 2017 5:00 PM Subject: Re: [M100] DVI cable Something somewhere fails to handle those trailing dots in that url, so let's remove them... http://tandy.wiki/Disk/Video_Interface#Work_in_progress -- bkw On Oct 26, 2017 4:48 PM, "Brian White" <bw.al...@gmail.com> wrote: I just recieved this new info from a member on the facebook group. http://tandy.wiki/Disk/Video_Interface#Work_in_progress... This cable looks home-made too, but he claims he knows it works and has used it himself. Since he not only used the numbers but also a clear picture and description of plain physical location, there is no ambiguity about it. Randy: THIS would seem to be the answer to your question finally. You can duplicate this guys cable using the same parts I linked to on that same wiki page. But ignore my tentative directions and pictures and go by Ted Saari's. (I'll update my directions and pics when I have actually verified it for myself, until then I'll just leave the "not yet verified, see below" note on mine. But it looks like this is what it's going to end up being.) It flies in the face of what I said so far! :) His cable has twists in it, so that tells me that his DIP connector is pinned the same as mine, because I will have to make twists like that too, in order to get the pinout he describes. The first cable I made was actually like that, and didn't boot either, but I convinced myself it was because the twists were wrong and I cut the end off that cable and scrapped it. So, I predict I still won't get my DVI working even after I duplicate this supposedly known-good example. I have another DVI on the way in, so maybe that one will work. Glad I ordered 10 dip connectors instead of 1! -- bkw
