The 19160 has a 50-pin narrow connection internally. It was a perfect choice for the peripherals I had. Its external connection is also narrow (micro-50 pin).

Everything is terminated properly. I've never had any termination or configuration problems with SCSI devices. I ran a couple of SCSI boards in one or other Amiga, and with x86: NCR 810, Buslogic (the last top-of-the-line desktop/workstation card they made) and now this Adaptec.

BTW, you could NOT do what I'm doing now with the older Adaptec cards like the 2940. Nor the Buslogic I had. They only allowed two connections, which would be the two ends of your chain.

The multichannel is the 39160 I believe, and I can't remember what they call the feature set on the 19160 for the support I mentioned above.
