Hi All: Looking for a SCSI 80 pin ->50 pin IDC -> USB converter. Can't find any such animal. IDC = IDE. Can't find that either.
Anyone know were I can get one?
Looking at SCSI 80 pin ->SCSI 68 pin ->to USB also. Can't find.
Or this converter?
Thanks
Robert

"80 pin SCSI to USB adapter"

Lots of adapters to be found. Even some videos.

For example:

https://www.bing.com/videos/rivervi...E060844AC1682F6EE8ABE060844AC1682F6&FORM=VIRE

As for which adapter to use - that depends of the devices you are trying to connect.

There may be proprietary cables and connectors involved.

Which means that the only source for the required adapters may be the device manufacturers.

The device documentation may list some applicable part numbers.

The plugs may fit but if the pinouts are different the adapter may not work.

Well perhaps I don't understand. 80 pin SCSI, 68 pin SCSI are standard connectors. USB is per standards.
I don't think anything I am thinking about would be proprietary. The only one confusing me is the 80 pin SCSI
to IDC (which is supposedly the same as 50 pin IDE). Neither of which i can find any adapter for.
If these are "standard" how can pin outs be proprietary?
Thanks

Well, the Adaptec adapters are REALLY expensive. 2-3 hundred dollars. Way to much for just fooling around with an old server.
I have an Adaptec 3944AUWD that was in server along with some others. It is LV Diff 68 pin connectors.

They may not be standard.

Even though the plug shape and pin counts match that does not mean that the required cable/plug is standard.

Not at all uncommon for manufacturers to swap pin positions and functions about etc. so only their cables wor with the manufacturers devices.

Hopefully that is not the case with respect to whatever (?) you are trying to connect.

However, at best, the cable or adapter will simply not work. At worse - something goes "poof".

Be really sure before plugging in and powering up.

Depends what you need. I found this old PCI-X Adaptec Ultra 320 card on eBay.com going for $9.60. This presupposes you have a sufficiently old (compatible) system to plug it in to. I agree though that more recent Adaptec PCIe SCSI cards are much more expensive. You could buy an old "junk" computer and a PCI-X card for less than a PCIe card on its own.

Admittedly, PCI-X is a pretty esoteric standard for home PCs, but I've managed to get PCI-X NICs to work in bog-standard PCI motherboards. You just leave the far end of the PCI-X connector hanging over the end of the PCI slot.

I've used 80-way to 68-way adapters to interface a bunch of Ultra 320 SCSI hard disks to an Adaptec RAID controller. I still have Adaptec SCSI cards in several old machines running Windows XP/7/10. It can be problematic getting Adaptec drivers to run in Windows 10, but it's sometimes possible to port them over from Windows 7 or 8 to 10.

I have an old full height 5.25in 30MB SCSI hard disk with a 50-pin IDC input, but my newer drives were 68 and 80-pin Ultra 160/320. My 25 and 50-way SCSI devices were mainly SCSI flatbed and film scanners, equipped with the old 50-way Centronics "printer" connector.

What device are you trying to interface? This will get you from 80-way to 50-way.

I have the 80 scsi to 50 to 68. Can't find a 68 SCSI to USB.
I have an Adaptec 3944 AUWD but the 68 's are forLV Dif SCSI.
I want to go from 80 pin SCSI to 7+15 Pin Parallel ATA PATA/IDE from there to USB
