Here's another I just made.. you would just cut the ATX-to-AT adapter and solder this inline. Top is input from the ATX side, bottom is output to the AT side. Then just put some heat shrink over the whole thing.

Tested, working design. Assemed on July 23rd, 2021.

That’s brilliant.

Wonder if maybe it could be made to use some sort of alternate attachment method for the wires though like spade terminals. Or little green lugs

I hate having soldered in wires in a application that gets moved often, and lets face it, we are always digging in our retro rigs.

Yes, you could design it to have ferrules on the cable ends with weidmuller blocks on the board. But I wouldn't call it much more reliable. Solder with heatshrink over it is plenty to keep it from bending/breaking. When you remove a connector, you don't pull by the cables, you pull from the connector.

I suppose the big heatshrink probably immobilizes it sufficiently 🤔

ATX2AT I think was the first solution to address the issue. But it was a very limited run. And I saw one problem with it, besides its price: it used a custom-built cable. I saw that as a problem. I didn't like the idea.

So I decided to try and address the issue. And I produced a clone of it. But it was little bit too much to bite so I chose another project which is this one right here. A simple in-line adapter to adapt a 24-pin ATX power connector to AT power connectors. Which lets me use modern ATX power supply with OVP, OCP and short circuit protection, but also adds the missing -5V.

Recently Phil's Computer Lab and Necroware released their own ISA card version, which is very clever and simple. I was impressed. Even envious of such clean design. But some commented they would rather have an in-line solution. One is cheaper, one does not take an ISA slot.

If I can improve this design, what should I add, include or change? Have you seen something else yourself? Please, comment. I have spent enough time on this to not release it. It is of no use if left unreleased. Input is welcomed.

And a final note: I have a bunch of these and I must somehow deal with them. If anyone wants to buy one, post me a message send me an email ananananas@gmx.us. I also have bunch of the ISA card versions assembled but I would like to get a comment from Phil or Necroware before I wish to sell those. I don't feel right selling them. Maybe I can release the Eagle files and if you guys want to take advantage of those and make available an assembled version, perhaps that would be a solution? Because if I could order a bunch of 30 of those since you guys released them, I see there is even more benefit to the community to let these be even more easily available. What do you think?

i saw the adapter being sold on ebay some weeks ago
i think it is now sold out

do you plan on selling more in the future?

Tested and 100% working.

Installed in the ATX to AT adapter (wire colors of the chinesium cable aren't right):

do you sell these on ebay=? with cables?

It’s nice to see so many solutions to this these days.

There is also this

(Which can be used with a wire also)

First pic is the latest version I modified, and the second pic is the previous version by wiretap
