68 pin SCSI in Amiga

I had problems when using simple adapter. HDD didn't work, just like  LoadWB said.

It will depend on the adapter and the hard drive. Simple adapters without termination require drives that have a jumper setting to switch them to narrow mode. On drives that have it the jumper is usually labeled SS or SW. I've got three large drives running using these $1 adapters, but some drives just don't work, even with the jumper set.

The more expensive adapters with termination should work with all drives, but I haven't tried one of these yet.

Wide cable terminators are usually no problem to obtain and once the bus is terminated in whole there's no need for 'half-terminators' any more. You can also use built-in terminators on the end drives instead of cable terminators. OTOH most wide drives run fine on a narrow bus, there are few refusing to (esp. IBMs).

I've not been able to get any IBM drives to work yet here. I got a bunch of drives from work when we switched from SCSI to newer formats. I was only able to get about one in four to work.

Note: I get my adaptors from eBay.

Here's the one I'm using:

Found this with a quick ebay search for SCSI Adaptor.
