Starting the cabinet all at once. It works! And here's how...

It could do that as well I suppose.... Just thinking here.
(It'd be a lot easier to do all this with a micro at this point  ;D)

Trying to do it with discrete components, you

I was looking around on the web and I saw an interesting way to tap into the ATX wires without actually modifying the power supply.

The trick is to use a short ATX extension cable.  You can solder additional wires into that cable where necessary and then insert it between the ATX connector on your PS and the ATX connector on your motherboard.
SoundDoc:
Okey, I put a couple more ideas into it, and I've got something that should work as I think you want...   ;D

Its not 100% polished, or tested, but they should both work and do the same thing. I just got my order from Bob Roberts (YAY!!) and I think I'm going to be busy for a while building my CP and finishing my cab, so I'm not going to have much time to tweak these out.

Anyway, basically it ties into 5Vcc, 5Vsb, and 120Vac, compares the cab status On/off with the computer status On/Off.
If the turns on, and the computers off, it sends a adjustable 0-2 second "ON" pulse, every 0-20 seconds (adjustable) until it gets 5vcc from the computer then it stops. Same the other way as well, if the Cab switches off, and the computers on, it sends a 0-10 second (adjustable) pulse every 0-60 seconds (adjustable until 5vcc drops, showing the computer as off.  That last delay may need to be adjusted longer, depends on how long your machine would normally take to shut down. Each of the pulse legths, and repeat delays are individually adjustable for your pleasure. ;)

The jpg is almost unreadable, but the PDF is up on my site:
http://dacab.datplace.com/Design.htm about 2/3 the way down.

Theres 2 circuits that do the same thing, one uses TTL logic for the comparitor, and 555 timers for the pulse control. The other uses discrete transistors for the comparitor (easier to find and cheper) and uses only 2 556 timers for the pulse control. Mix and match, and enjoy!

If anyone really wants one, I could be pursuaded/bribed to build it up and test, I just don't have the timeto work on this anymore if theres no interest, I've got some funky circuits to build for my cab.....

I GOTTA GO BUILD A CAB!!! (ok still 3 hours of work, but then I'm going to... Three people have allready walked by and "fondled" my new trackball. I might try to sneak out of here early)

holy...! i think ill stick to my lonesome, works 98% of the time, relay!
Lilwolf:
btw, the 3rd post was stating that my old emplorers had to get a way to do this.  And they had an expert build something... they couldn't use a relay for some reasons...

And that they had a solution for about $25..

After doing all this... Do you think that was a realistic price?  (seriously... I've considered trying to get them to sell a few here or at least mention it... just didn't know if it was worth it)
