Any ideas?

I got the first shipment of parts for the crack rack yesterday...

All the motherboards are AT, but I have an extra 300W ATX PS, is there anyway to use it with an AT MB? I can't figure out which pins are for what on the motherboard, and I can't figure out how to turn on the powersupply without an ATX motherboard because of the low power line which turns it on.

Is it possible to power them with this powersupply? Or do I have to buy an AT PS?

No flame here, but that's not the case. An ATX power connector is 2-wide while AT is only one, and the ATX power connector "pins" of been "geometrically altered" (for lack of better words) to key the connector so it only can fit on one way.

It would be pretty tough to wire up a converter since you have to convert some voltages (there's no 3.3v wire in the AT spec, but ATX has it). Also you'd have to create a switch through the power connector since that is how the motherboard turns the power supply on and off.

I'm not saying it can't (or even't hasn't) been done, but it wouldn't be easy and probably wouldn't be worth the hassle to do. I know I have an AT power supply around here somewhere (other than the one I'm currently using for my K6-2 testbed). If I find it, I'll let you know and ship it to you. If I get around to doing all of that (<g> ), I'll toss in my K5 (great cracker for the dough) and maybe a TX motherboard. I'll see.

Anyway.. good luck to your project spdk8tr (and bkehoe if you're eavesdropping ). Keep us up to date, and let us know when Gotoworld.com starts releasing how many hours we've accumulated.

Thanks Joel! What speed is that K5?

I can't believe all the support I have recieved so far on the project! I thought I'd be on my own, but it looks like everyone is starting to get into it!

I'll let you know about the hours when it's available. It should be fairly soon. I can however tell you how many people are participating:

22 "friends"
8 "associates"
1 referred by associates

Monthly income: $152

The K5 is a PR133 (~107 MHz CPU), I believe. Of course, I have to find that, too.

I'm going to be building a car mp3 player in the near future (uhh.. Senior project.. YEAH ) so I have to be careful what I give out since I'm never sure what I'll need or use. But I think I can spare that K5, esp. since I know it has the best rc5 keyrate/MHz ratio of any CPU. I think it gets like 310-330 kkey/s (don't remember exactly). It won't overclook a hoot though (fixed multiplier )

Phew!!!

Ii thought it was something to do with my account - its not mine!

Ii was beginning to wonder when the date came and went, with no update....

Anyway, I'll be getting round to updating my site soon, but am busy now with 3 other sites that I'm getting paid for (will put some of the money from that towards my RC5Cracker project).

This is really streching my memory cells, but from what I remember reading a while back about AT/ATX power supply plugs is that they are identical. The AT plugs were 2 plugs and all the ATX plugs did were to combine them into one. If you put the orange wires on the outside, they will match up.

Please don't flame me for any worng info here, I am no expert on power supplies, only trying to give you an idea to check out!
