Title: Blizzard SCSI IV and Power Tower options
Post by: AltRN8 on February 06, 2010, 02:42:54 AM

So I am putting a 1200 into a Power Tower. The rig includes a Blizzard 1260 and complimentary Blizzard SCSI IV. I have a few questions about what SCSI options I have since the Blizzard has such a weird connector.

1) Are there any splitter cables available that allow internal and external scsi equipment? Anyone know where I could source something like this or is it a build only opiton?

2) Anyone know what the pinning is on the Blizzard PPC internal SCSI cable would work as a replacement cable if I wanted to install everything internally? Anyone have the pinout for this cable?

Anyone else using this kind of setup? What did you do to work around the short cable?

Thanks.

I have an external to internal cable, but I have no idea if it was custom built or not. I think the SCSI Kit cable itself is just a standard 26 (or is it 24) pin IDC to 25pin SUBD, so a longer one should at least get your external devices accessible. I think they were fairly common for extra PC parallel ports back in the day...

AltRN8: If you can get the correct IDC connector, and ribbon cable, you could have someone make a longer cable for you. Just use the original cable as a guide and match up the wires / IDC connections. With that said, I still use my original (too short) SCSI cable, with a short standard cable going out the back of the tower, because a) all my devices are external anyway, and b) I have no friends...

as for the internal / external adapter... I've seen them.  They are usually small PCB's rather than a cable, per se. You could find these on EBay, I'm sure. I got something similar from stripping down dead PC's / SCSI boxes, etc.... so that might be an option....

You can just get a 25 pin gender changer (http://cgi.ebay.com/25-Pin-Male-to-Male-M-M-Mini-Gender-Changer_W0QQitemZ220380682445QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item334fb658cd), and a 25 pin female to 50 pin IDC adapter (http://cgi.ebay.com/New-SCSI-INTERNAL-50-Pin-To-EXTERNAL-25-Pin-Adapter-I-O_W0QQitemZ380203395987QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5885e36b93), and you can connect a normal 50 pins SCSI cable. That's what I have done a couple of times in the past.

Thanks for all the suggestions! Extremely helpful.
