Power Macintosh 7600/120 SCSI drive

Interesting, I have a 7600/132 with a Sonnet G4 replacement cpu card, added a second SCSI drive...thought seriously about getting a PCI card with SATA instead but never did...thing just would not die.

Have you looked at OWC, http://www.macsales.com to see if they have a replacement card that will work?

>Is it possible to adapt the ribbon cable to accept IDE?

A pure cable adaption is not sufficient. SCSI is a completely different protocol. A web search for something like SCSI-IDE adapter, SCSI-CF adapter and/or SCSI-SATA adapter may give you some ideas about hardware available. However, be prepared to experiment.

If you want to connect a bootable IDE hard drive, you'll need to install a Mac-compatible (PC versions won't work) Ultra ATA-66 or ATA-100 PCI controller card, such as this Sonnet card listed at ebay. Make sure that your 7600 supports the card. You can also seach the web for the (discontinued) Acard AEC-6260M Ultra ATA-66 controller card. I just checked ebay for 50-pin SCSI hard drives and can't believe what they're selling for, compared to what I paid for comparably-sized drives 10 years ago. That's what scarcity does, even when the demand is low. There was an ebay seller (Tony Lafrenz) who specialized in used SCSI hard drives, but time and technology's evolution may have retired his ebay store by now. Keep in mind that anything you find will likely be used and as old, if not older, than your failed drive. This could limit the service life that you might hope to get from a used drive.

Do not forget that external SCSI port! Zip drives are a dime a dozen and Zip floppies are also easy to find. The great thing about SCSI is that you can boot OS 8 from an external zip disk.
