Ok doing a favor,

9600/300mhz

With a 4GB SCSI drive. Found a cheap 9 GB SCSI drive replacement

$9.99 On Sale!
Seagate ST19171WC, SCA 80 Pin Ultra SCSI Hard Drive. 9.1 GB, 7200RPM, 9.7ms access time. Condition: New Pulls, Warranty: 30 days.
http://www.softwareandstuff.com/h_65gbhdrive.html

But do i need this 80 to 50 pin adapter to get it to work?
Description: This product will converts the 80-pin SCA SCSI connector on a hard drive to 50-Pin narrow SCSI
http://www.softwareandstuff.com/h_misc_80sca50l.html

And can I put two SCSI drives in the 9600 with a scsi ribbon that has two female connectors just as long as I put them different scsi ids?

thanks for the help

Yes you do. Sometimes the adaptors are quite expensive and it's cheaper to buy a 50-pin drive...

And you can put up to 7 SCSI drives in the Mac on the internal (SCSI-2) bus. Every device must have a unique SCSI ID

The internal CD will be occupying 1 slot...

Thank for the info
as for the converter it seems pretty cheap

80-Pin SCA to 50-Pin SCSI Adapter
$14.95 $9.95 On Sale!

Condition:New
Warranty:30 Days
Description: This product will converts the 80-pin SCA SCSI connector on a hard drive to 50-Pin narrow SCSI

But it would be cooler if the drives a a 50 to begin with then the final price would be just the 9.99 + 7.50 shipping, But I need the drive and the adapter 9.99 + 9.95 + 7.50 shipping.

But I will check this final price against OWC or something.

By the by what kind of computer take the 80 pin? Is 50 narrow SCSI and 80 pin Ultra? And one more so most internal stuff in a mac will 50 pin?

Thanks for the help

They're SCA (single connector attachment) drives.

"Instead of the use of discrete cables, the drives are plugged directly into the system. A single connector is used that includes all of the signaling and power inputs and outputs needed by the drive."

So, how are you powering it? Does the adapter you get have a power port?

Whoa,

Thanks schalliol.
This drive might be more trouble then it is worth but then messing with the mac is always fun anyways!!

As for the adapter from 50-80 here is a picture
http://www.softwareandstuff.com/medi...sc.80SCA50.jpg

and here is the link to buy it http://www.softwareandstuff.com/h_misc_80sca50l.html

So I think the answer to you question is does the adapter have a power source. Yes, because the left had side has a power connector.

But now a question of personel preference. Would you want to add an 9GB 80 pin w/ 50 pin adapter to a PowerMac 9600/300 for a price of $27.44 (HD 9.99 + Adapter 9.95 + shipping 7.50)

No problem.

I've always heard that they're lots of trouble, so I've avoided them.

If you just want more storage space, go for it.

For better speed, order two and hang them off the 10MBps bus with the 4GB on the 5GB. Then use SoftRAID LLC's RAID software to make a RAID 0 array. You must be careful about the spacing of your machine to ensure that you can fit the drives with the adapters.

If you really want to get much greater performance we're talking more bucks and a new interface card and better drives.

I think I will forgo this option and have the person save the money for a PCI ATA adapter card or just look for cheap 50 pin drives instead of messing about with adapters for 80 pins

Thanks for help schalliol you have enlightened me in the ways of SCSI

You're very welcome, I'm happy to help. Unfortunately SCSI can be a pain sometimes and these days is getting beat out by IDE for most applications. However, IDE certainly is cheaper, as you can note from my dual 9 GB SCSI drives and my dual 60GB IDE drives.

BTW, I love the 9600. I had 5 hard drives, 5 PCI cards (one has to be removed for drives on the bottom, a CD-ROM, a CD-RW, but had to pull out the floppy for the internal space ;-)
