Centris 610 tower

[coius]

So I got a Centris 610 motherboard coming in the mail with a full 040 and a spare oscillator (for the proper speed) and I was thinking instead of mounting in a Centris 610/Quadra 605 desktop unit, I would mount it in an old ATX tower and the magical use of a dremel and some sheet metal, I can make it fit in an ATX tower or whatnot. I thought about putting two hard drives, a Zip drive and a SCSI CD-ROM, then throwing it on Ethernet and make it into a small webserver. If it runs 8.1 I will have partitions higher than 2GB via HFS+ for the data drives.

I would have to do HFS for the boot drive I am pretty sure (HFS+ only supports PowerPC for boot, right?) and then throw a bunch of my older software on it. Maybe even switch my webpage hosting to it for grins and giggles.

Anyone think this might be a good idea, or is it better to source the proper case?

I would need to modify an ATX power supply to get the proper input for the case, but I am not sure until it comes what connector it uses (AT? ATX?) so I will see. what I can do.

If it is a Centris 610 with a full '040, doesn't that make it a Quadra 610? As I recall, the logic board part number is the same (I have one of each).

I need to install the CPU with the oscillator. It's not pre-installed. There's just a 68LC040 in it. but the sender also sent a full 040 for my to install (i need to solder in the oscillator, easy peasy for me though.

The Full 040 is already installed. No LC040 included.

Just the 15mhz and change Oscillator needs to be installed yet. witch should yeld 30 - 31mhz.

Ah, ok didn't understand that right. Ok thanks! I will be sure to let you know when I get back home that all is well... Do you have the locations I am supposed to solder these at? is there like a guide i can follow?

The 10mhz oscillator is right next to the cpu. The replacement 15mhz oscillator is a older style package(through hole), but the pin out is the same, might have to solder 4 legs on the oscillator if the leads are not long enough to touch the proper pads.

You can remove the old oscillator, or you can "by-pass" it and just attach the new oscillator to its legs,

kind of how a clock chip clip thingie works. I've never done it the bypass way, I just remove the old oscillator with 2 soldering irons.

I already installed the inductor and oscillator mod for the Sonic Networking IC. So it could have its own (10 MHZ Clock) derived from a 20mhz oscillator, separate from the CPU.

Basically with the Centris 610 model /w networking, the cpu and the networking I/C shared the same 10mhz clock from the cpu, to save cost.
