thank you ^^ and done.

will be really helpful testing unknown condition boards... or uh, boards that have the cache sockets mounted the wrong way *cough*

Yep. These are too expensive to use as generic converters in all systems, but on the test bench for that all-important first boot they should be a lifesaver.

I backed too of course 😀

I think they're regular Molex products. Correct me if I found the wrong product here.

I know they do exist, they're just hard to come by and pretty expensive in low quantities, so I understand not going that route.

a good DC/DC converter with 20A+ costs about the same as a good ATX PSU 😉
and if you add up the ATX PSU you need to power the adapter itself and an extra DC/DC board I think it makes more sense to just get an ATX PSU in the first place.

also I think the main purpose behind the board is protecting low-power stuff from too much current from a modern PSU in case of a failure.

Some answers :

1. 20/24 pins Mini-Fit JR (Molex) Male connectors for PCB mount are rare and expensive. It will also be bulky because there is no angled male connectors. And more important, the whole converter will be limited to PC only because it must follow the standard ATX pinout at output. I really want to keep the optional GPIO that can be useful on some Atari/Amiga (ie: to generate a sync signal)

2. The ATX2AT Smart Converter is rated to 10A @ 5V, 5A @ 12V, 0.4A @ -12V and 0.4A @ -5V (for a total of ~120W max excluding peripherals/HDD/ODD). That covers all PC motherboards with AT P8/P9 connectors, from 8088 to Pentium/K6, and almost all vintage "family" computers up to ~1995. Basically, everything that don't require +3.3V from the ATX era.

Funded with more than 150 backers, thank you all 😀

Extremely cool! Looking forward to getting this nice piece of equipment!

I'm so disappointed with myself for missing this kickstarter. 😀 I'd like about 5 of these right now.

I ordered a bit more quantities.

Just drop me an email at dev // x86 - fr and I'll send you a message when they're ready 😀

Cool! Looking forward to the finished product! I hope you are recovering well!

Will do!

hey, hope you're doing well, got any news, or still waiting for shipments from china? ^^

I received mine today! Thanks!

Got mine as well. Am impressed! Although one thing: I had to set the +12V to 3.0A or else with a couple of cards and two floppy drives it would trigger on power on. After everything has settled it uses 0.2A on +12V. 2.2-2.5A on +5V.

I have a 286@12MHz, two floppies, Compact Flash, Multi I/O, TNDY, SnarkBarker, PC MIDI, ET4000.

Ohhhh.. yay! Can't wait to get the couple I ordered.

*waiting patiently* 😁

Sneak peek at what you will receive:

Oh man, I need one of these for my IBM PS/1 and another as an extra!

This is making my 386/486 dreams come true - when do I have another shot at getting one?

Can I still use the regular AT power on switch with this? Do I just connect the corresponding 2 pins on the board with the existing switch?

It has a regular two pin connector for ATX power switches. Since ATX switches are momentary, your AT power switch might not work as expected. AT power switches actually switch the mains voltage, as far as I understood. I guess you can technically still use it for switchting, but I guess it's more like click on/click off for turning on, and same again for switching off. Replacing it with a momentary switch would be better, I guess.

it's here! :3

now if only I had space to start testing boards x3
