I am having trouble finding the correct adapters to go from the original drives to usb A or C for these drives. Can anyone point me in the right direction? Drive connections

    I put up a wrong answer (now deleted since you don’t have IDE or SATA drives), getting a vintage Mac of this era might be an economical way to go depending on how many drives and what you want to do with the data… the only USB access to these is likely to be a keyboard on the computer with a SCSI card to read these drives or a USB port to copy the data to a thumb sized flash storage drive.

  • Are you trying to recover known user data, or just curious about what's on these drives? There's any amount of vintage Mac OSes and software available to download if you're just after that.

  • @bmike I have no idea about MAC's, but for PC SCSI was basically reserved for high end market, so you should check carefully if the HW you procure supports it, even if it's from the correct era. I would honestly go with PCI-E U320 card...

Both are SCSI; one is 68P and one is 50P scsi. 68 pin is the plastic connector, while the 50 pin is the pin header format in a plastic shroud.

Anything that can talk SCSI-2 or newer should work. Realistically that means a U320 card today. You will also need an adapter between 50P and 60P; the only real difference relevant to you is the pin count; you only need an adapter cable.

Your best bet is probably to find someone with interest in old computers near you, that can make a image. Otherwise, there's PCI-E SCSI cards available quite cheaply on e.g. Ebay - but it will probably cost you a bit of money (~100-200USD) for the following items:

  • SCSI card (either 50P or 68P; 68P U320 is probably most realistic today)
  • SCSI cable 68P-68P
  • Adapter 50P-68P
  • SCSI cable 50P-50P

In addition you need a computer with PCI-E slot. If you only have OS X computers, I have no idea what SCSI cards are supported on that platform; on Linux almost any card will be supported, and it will be fine for imaging the drive - that can be done under any OS.

Once you have your image, either created on your own computer, or by some local enthusiast, you can mount it following this Q&A.

The black plastic drive is SCSI. I haven't seen a SCSI to USB available. There were several types/versions, named things like SCSI-2, SCSI-3. So you'd need to identify which (Wikipedia would have pictures). I recommend finding a traditional computer shop and see if they have an old computer or server that has your SCSI type and can they image the drive and give you the image file, or use software to read the Mac file system format and copy the files to a new (more modern) drive. A data recovery company is very likely to have the compatible hardware too, but likely to be more expensive.

    Both are SCSI. And SCSI has excellent backwards compability. Today you'd get U320-card.
